74HCT132D-Q100,118

Overview

The Nexperia 74HCT132D-Q100,118 is a quad 2-input NAND gate with Schmitt-trigger inputs, designed for automotive applications. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 14-SOIC package (SOT108). The device features AEC-Q100 qualification, ensuring reliability under harsh conditions. Key electrical parameters include a maximum static current of 2 µA, output drive capabilities of 8mA high and low, and a maximum propagation delay of 15ns at 5V with 50pF load. It functions across an extended temperature range from -40°C to +125°C.

Feature Summary

• Schmitt-trigger inputs provide noise immunity and transform slowly changing signals into sharply defined outputs.
• AEC-Q100 qualified for automotive electronics, ensuring robust performance in demanding environments.
• CMOS technology offers low power dissipation while maintaining high noise immunity.
• Input clamp diodes allow interfacing with voltages exceeding VCC using current-limiting resistors.

Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify the specific suffix 'Q100' confirms AEC-Q100 automotive qualification and HCT logic family compatibility. Ensure the 14-SOIC package matches your PCB footprint requirements. Confirm RoHS compliance status if required by your manufacturing standards. Check for any recent Product Change Notifications regarding assembly or labeling updates that may affect part marking or sourcing channels.

Selection Notes

Select this component when automotive-grade reliability is required alongside TTL-compatible input levels. The HCT series ensures compatibility with standard TTL logic families, unlike the HC series which requires CMOS levels. Verify that the 4.5V to 5.5V supply range aligns with your system's power architecture. Consider the 14-SOIC package dimensions against available board space constraints.

Part Context

This part belongs to the 74HCT132 family of quad 2-input NAND gates with Schmitt triggers. It is the automotive-qualified variant of the standard commercial 74HCT132. Manufactured by Nexperia, it shares functional similarities with other 74-series logic but is distinguished by its extended temperature range and automotive certification.

Replacement Considerations

Direct substitutes include other AEC-Q100 qualified 74HCT132 variants from manufacturers like Texas Instruments or onsemi, provided they match the 14-SOIC package and electrical specifications. Ensure pinout compatibility and identical logic functionality before substitution.

FAQ

What is the difference between 74HC132 and 74HCT132?

The 74HCT132 uses TTL-compatible input levels, allowing direct interface with TTL logic, whereas the 74HC132 uses CMOS input levels. Both feature Schmitt triggers and similar electrical characteristics otherwise.

Does the 74HCT132D-Q100 support voltages higher than VCC?

Yes, the inputs include clamp diodes, enabling the use of current-limiting resistors to interface inputs to voltages exceeding VCC safely.
