4-axis ESP32 DevKit v1 to DM542T stepper driver level shifter board using two SN74AHCT125N DIP buffer ICs, 5V screw-terminal power input, driver signal terminals, and 100 mm x 60 mm PCB.

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

Voltage Level Translator Bidirectional 1 Circuit 8 Channel 60Mbps 20-TSSOP This device is an 8-bit non-inverting level translator which uses two separate configurable power-supply rails. The A port tracks the VCCA pin supply voltage. The VCCA pin accepts any supply voltage between 1.4V and 3.6V. The B port tracks the VCCB pin supply voltage. The VCCB pin accepts any supply voltage between 1.65V and 5.5V. Two input supply pins allows for low Voltage bidirectional translation between any of the 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes. When the output-enable (OE) input is low, all outputs are placed in the high-impedance (Hi-Z) state. To put the device in the Hi-Z state during power-up or power-down periods, tie OE to GND through a pulldown resistor. The current-sourcing capability of the driver determines the minimum value of the resistor. • No direction-control signal needed • Maximum data rates: – 110Mbps (push pull) – 1.2Mbps (open drain) • 1.4V to 3.6V on A port and 1.65V to 5.5V on B port (VCCA ≤ VCCB) • No power-supply sequencing required – either VCCA or VCCB can be ramped first • Latch-up performance exceeds 100mA per JESD 78, class II • ESD protection exceeds JESD 22 (A port): – 2000 V Human Body Model (A114-B) – 150 V Machine Model (A115-A) – 1000 V Charged-Device Model (C101) • IEC 61000-4-2 ESD (B-port): – ± 8kV Contact Discharge – ± 6kV Air Discharge #commonpartslibrary #integratedcircuit #logic #translator #levelshifter

Polymeric PTC Resettable Fuse 6V 500 mA Ih Surface Mount 0603 (1608 Metric), Concave polyfuse 500mA 0603 The 0603L050YR is a surface-mount resettable fuse based on polymeric positive temperature coefficient technology, designed to provide overcurrent protection in compact electronic circuits. Under normal operating conditions, the device exhibits low resistance and allows current to pass with minimal power loss. When exposed to an overcurrent condition, the device transitions to a high-resistance state, effectively limiting the current and protecting downstream components. Once the fault condition is removed and power is cycled or the device cools, the fuse automatically resets to its original low-resistance state. This component is optimized for space-constrained applications requiring reliable, resettable protection, such as portable electronics, battery-powered systems, and low-voltage signal lines. Its small form factor enables integration into dense PCB layouts while maintaining compliance with industry safety standards for overcurrent protection. Package and Mounting: Surface-mount device in standard 0603 footprint, compatible with automated assembly processes including reflow soldering. Electrical Characteristics: The device is designed to maintain normal operation at a defined hold current level and transition to a protective state when the current exceeds its trip threshold. It operates within low-voltage circuits and provides fast response to fault conditions while minimizing nuisance tripping under typical load variations. Functional Behavior: The fuse operates by increasing resistance sharply in response to thermal energy generated by excess current. This behavior reduces current flow and limits fault energy. After removal of the overcurrent condition, the device gradually returns to its conductive state, enabling repeated use without replacement. Applications: Suitable for use in power lines, battery packs, USB interfaces, consumer electronics, and other low-voltage systems where resettable overcurrent protection is required. Compliance and Reliability: Designed to meet relevant safety and environmental standards for electronic components, ensuring stable performance across specified operating conditions and long-term reliability in field applications. #commonpartslibrary #fuse #Circuit-Protection #PTC #ptc #polymeric
