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 60V 500 mA Ih Surface Mount 2-SMD 500mA resettable fuse pptc The SMD050F-2 is a surface-mount resettable fuse (PPTC – Polymer Positive Temperature Coefficient) designed to provide overcurrent protection in low-voltage electronic circuits. It operates by increasing its resistance significantly when excessive current flows, thereby limiting current and protecting downstream components. Once the fault condition is removed and the device cools, it automatically resets to its low-resistance state, enabling normal operation without replacement. This component is commonly used in power supply lines, USB ports, battery-powered devices, and general electronic protection applications where space-saving and reliability are important. Key Features Resettable overcurrent protection (self-recovering) Surface-mount package for compact PCB layouts Low resistance in normal operation Fast response to fault conditions Automatic reset after fault removal RoHS compliant and lead-free Electrical Characteristics Hold current: 0.5 A Trip current: 1.0 A (typical) Maximum voltage: 60 V Maximum current: 40 A (fault current rating) Initial resistance: low resistance range suitable for minimal voltage drop Resistance after trip: significantly increased to limit current Thermal Characteristics Operating temperature range: -40°C to +85°C Trip time dependent on applied current and ambient temperature Reset time dependent on cooling conditions Mechanical Characteristics Package type: Surface-mount (SMD) Compact footprint suitable for dense PCB layouts Compatible with standard reflow soldering processes Applications USB and peripheral port protection Power supply and DC line protection Battery pack protection Consumer electronics Industrial control circuits Compliance and Standards RoHS compliant Halogen-free (depending on manufacturer variant) Meets industry standards for resettable fuses #commonpartslibrary #circuitprotection #ptc #fuse
