The NE555 devices are precision timing circuits capable of producing accurate time delays or oscillation. In time-delay or monostable operating modes, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle are controlled independently with two external resistors and a single external capacitor. Each timer has a trigger level equal to approximately one-third of the supply voltage and a threshold level equal to approximately two-thirds of the supply voltage. These levels can be altered by use of the control voltage pin (CONT). When the trigger input (TRIG) is less than the trigger level, the flip-flop is set and the output goes high. If TRIG is greater than the trigger level and the threshold input (THRES) is greater than the threshold level, the flip-flop is reset and the output is low. The reset input (RESET) overrides all other inputs and is used to initiate a new timing cycle. If RESET is low, the flip-flop is reset and the output is low. Whenever the output is low, a lowimpedance path is provided between the discharge pin (DISCH) and the ground pin (GND). Tie all unused inputs to an appropriate logic level to prevent false triggering. The output circuit is capable of sinking or sourcing current up to 200mA. Operation is specified for supplies of 5V to 15V. With a 5V supply, output levels are compatible with TTL inputs. Features - Timing from microseconds to hours - Astable or monostable operation - Adjustable duty cycle - TTL-compatible output can sink or source up to 200mA - On products compliant to MIL-PRF-38535, all parameters are tested unless otherwise noted. Applications - Pulse-shaping circuits - Missing-pulse detectors - Pulse-width modulators - Pulse-position modulators - Sequential timers - Pulse generators -F requency dividers - Industrial controls

20 Position Receptacle Connector 0.100" (2.54mm) Through Hole Tin The SSQ-110-03-T-D is a through-hole dual-row socket strip receptacle connector manufactured by Samtec, designed for board-to-board and pin header mating applications using the industry-standard pitch spacing that has been dominant in through-hole PCB interconnect design for decades. It belongs to Samtec's SSQ series, a family of square-post socket strip connectors that accept standard square-pin headers and are widely used across prototyping, instrumentation, test and measurement, embedded systems, industrial control, and general-purpose PCB stacking applications. As a socket strip of the receptacle gender, the SSQ-110-03-T-D is intended to receive a mating male pin header, creating a reliable and separable board-to-board or wire-to-board connection. The dual-row configuration provides a higher contact density within a given board length than a single-row socket, which is why dual-row socket strips in this pitch class are extensively used in applications such as microcontroller and single-board computer expansion connectors, module-to-baseboard interfaces, and other designs where a significant number of signal, power, or ground connections must be made across a single separable connector interface. The connector features square solder tails for through-hole PCB mounting, with the "-T" suffix in the part number designating the square post tail style, which provides a well-defined mechanical footprint and reliable solder joint formation in wave solder and hand-solder assembly processes. The "-D" suffix indicates the dual-row configuration. Contact material is phosphor bronze, a widely used spring-contact alloy chosen for its combination of good electrical conductivity, excellent spring properties that maintain consistent contact force across many mating cycles, and resistance to stress relaxation over time. The contacts are finished with matte tin plating over nickel underplate, providing a solderable, cost-effective contact surface suitable for the majority of general-purpose signal and low-power applications for which this connector class is typically used. The insulator body is molded from black liquid crystal polymer, a high-performance engineering thermoplastic that offers the high dimensional stability, excellent electrical insulation properties, and high-temperature resistance needed to withstand wave soldering and reflow-adjacent thermal exposure during PCB assembly. The material also carries a UL94 V-0 flammability rating, reflecting its self-extinguishing behavior in the event of an ignition source, which is required or preferred in many end-product regulatory compliance frameworks. The SSQ series is widely used in conjunction with Samtec's TSW series male pin headers as a complementary mating pair, and the connector is compatible with a broad range of standard square-pin headers from other manufacturers that conform to the same pitch and pin geometry, making it a versatile choice for general-purpose through-hole header applications.

Power Switch/Driver 1:1 N-Channel 500mA PowerSSO-12 8-channel protected high-side 12 V output switch IC The VNI2140J is a monolithic device designed using STMicroelectronics' VIPower technology. The device drives two independent resistive or inductive loads with one side connected to ground. Active current limitation prevents a drop in system power supply in cases of shorted-load, and built-in thermal shutdown protects the chip from damage due to overtemperature and short-circuit. In overload conditions, channel turns OFF and ON automatically to maintain the junction temperature between TTSD and TR. If the case temperature reaches TCSD, the overloaded channel is turned OFF and restarts only when case temperature decreases down to TCR. In order to avoid high-peak current from the supply, when more than one channel is overloaded the TCSD restart is not simultaneous. Non overloaded channels continue to operate normally. The open-drain diagnostics output indicates overtemperature conditions and open-load in OFF-state. Features • Nominal current: 0.75 A per channel • Shorted-load protections • Junction overtemperature protection • Case overtemperature protection for thermal independence of the channels • Thermal case shutdown restart not simultaneous for the various channels • Protection against loss of ground • Current limitation 1 A per channel • Undervoltage shutdown • Open-load in OFF-state and short to VCC detection • Open-drain diagnostic outputs • 3.3 V CMOS/TTL compatible inputs • Fast demagnetization of inductive loads • Conforms to IEC 61131-2 Applications • Programmable logic control • Industrial PC peripheral input/output • Numerical control machines #VNI2140J #STMicroelectronics #VIPower #HighSideSwitch #SolidStateRelay #PowerManagement #IndustrialAutomation #PLC #LoadDriver #PowerSSO12
