74ALVC02PW,112

Overview

The Nexperia 74ALVC02PW,112 is a quad 2-input NOR gate in a TSSOP14 package. It operates on a supply voltage of 1.65 V to 3.6 V with Schmitt trigger inputs for slow signal tolerance. The device supports partial power-down via IOFF circuitry and meets JEDEC standards for various voltage ranges. Propagation delay ranges from 1.0 ns to 5.4 ns depending on voltage. It withstands ESD up to 2000 V (HBM) and exceeds 250 mA latch-up performance.

Feature Summary

• Schmitt trigger action on all inputs provides tolerance for slow rise and fall times.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent backflow current.
• Overvoltage tolerant inputs allow direct interfacing with TTL levels without external resistors.

Applications

• Mixed 3.3 V and 5 V logic systems
• Partial power-down applications requiring backflow prevention
• Signal conditioning for slow transition waveforms

Procurement Notes

Verify the specific ordering suffix '112' against the manufacturer's current database to confirm availability status and exact packaging configuration. Confirm that the TSSOP14 variant matches the required thermal derating specifications for the intended operating temperature range of -40 °C to +125 °C before finalizing procurement.

Selection Notes

Select this component when a quad NOR function is required within the ALVC family. Ensure the design accommodates the specified propagation delays at the target supply voltage. Verify that the input transition rates do not exceed the recommended limits for the chosen voltage range to maintain timing integrity.

Part Context

This part belongs to the 74ALVC series of high-speed CMOS logic devices manufactured by Nexperia. The PW suffix indicates the TSSOP14 plastic thin shrink small outline package. It is part of a broader portfolio of logic gates designed for low power consumption and wide supply voltage compatibility.

Replacement Considerations

Check for 74ALVC02D or 74ALVC02BQ if different packages are acceptable. Verify pinout compatibility with existing PCB layouts before substituting.

FAQ

How does the IOFF feature benefit the circuit?

The IOFF circuitry disables the outputs when the device is powered down, preventing potentially damaging backflow current through the device.

What is the maximum latch-up performance rating?

The latch-up performance exceeds 250 mA per JESD78 Class II.
