74ALVC32PW,118

Overview

The Nexperia 74ALVC32PW,118 is a quad 2-input OR gate in a TSSOP14 package. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an ambient temperature range from -40 °C to +125 °C. The device features Schmitt trigger inputs for slow signal tolerance and IOFF circuitry for partial power-down protection. Propagation delay ranges from 1.0 ns to 3.2 ns depending on voltage and temperature.

Feature Summary

• Schmitt trigger action on all inputs provides tolerance for slow rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow current.
• Overvoltage tolerant inputs allow direct interface with TTL levels.

Applications

• Partial power-down mode operation
• Mixed 3.3 V and 5 V logic environments
• Signal buffering with slow transition times

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the component status aligns with production requirements. Check for any recent product change notices regarding assembly or labeling updates before finalizing procurement specifications.

Selection Notes

Select this component when a quad OR gate function is required with low power consumption and high noise immunity. Ensure the application environment stays within the specified 1.65 V to 3.6 V supply range. Consider the TSSOP14 package dimensions for PCB layout constraints.

Part Context

This part belongs to the 74ALVC family of high-speed CMOS logic devices. It is manufactured by Nexperia USA Inc. and is designed for applications requiring fast switching speeds and low power dissipation. The PW suffix indicates the TSSOP14 plastic thin shrink small outline package.

Replacement Considerations

Direct substitutes include other 74ALVC32 variants such as the SO14 (74ALVC32D) or DHVQFN14 (74ALVC32BQ) packages from Nexperia. Cross-brand replacements must match the ALVC logic family specifications and pinout compatibility.

FAQ

Does the 74ALVC32 support partial power-down?

Yes, the device includes IOFF circuitry that disables the output to prevent backflow current when powered down.

What is the input characteristic for slow signals?

All inputs feature Schmitt trigger action, making the device tolerant of slow rise and fall times.
