74HCT00D-Q100,118

Overview

The Nexperia 74HCT00D-Q100,118 is a quad 2-input NAND gate qualified to AEC-Q100 Grade 1 for automotive use. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL input levels, CMOS low power dissipation, and high noise immunity. Propagation delay is specified at 12 ns typ at 4.5 V with 50 pF load. Input clamp diodes allow interfacing to voltages exceeding VCC using current limiting resistors.

Procurement Notes

Verify the specific ordering code suffix matches the required package variant. Confirm that the component meets the intended environmental specifications for the target application. Ensure compliance with RoHS directives and REACH regulations as documented by the manufacturer. Cross-reference the datasheet revision date against the production batch to ensure specification accuracy.

Selection Notes

Select this component when TTL-compatible inputs are required within an automotive environment. The SO-14 package provides a compact solution for surface-mount assembly. Consider the propagation delay and power dissipation characteristics relative to system timing requirements. Verify that the supply voltage remains strictly within the 4.5 V to 5.5 V operational limits.

Part Context

This part belongs to the Nexperia 74HCT00-Q100 series, which includes variants like the 74HC00D-Q100. While sharing similar packaging and automotive qualifications, the HCT series specifically targets TTL logic compatibility. The D-package designation indicates the SO-14 plastic small outline package configuration.

Replacement Considerations

Direct substitutes include other 74HCT00 variants from different manufacturers that meet AEC-Q100 Grade 1 standards. Verify pinout compatibility and electrical parameters such as propagation delay and output drive current before substitution.
