74HCT00D/AUJ

Overview

The 74HCT00D/AUJ is a quad 2-input NAND gate manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 6.0 V, with typical operation centered at 5.0 V. The device features TTL-compatible input levels and CMOS low power dissipation. It includes clamp diodes on inputs for interfacing voltages exceeding VCC. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Operating temperature ranges from -40 °C to +85 °C or up to +125 °C. Propagation delay is typically 12 ns at 4.5 V and 10 ns at 5.0 V.

Procurement Notes

Verify the specific ordering code against the manufacturer's current datasheet to ensure package and temperature grade alignment. Confirm that the AUJ suffix corresponds to the SO14 plastic small outline package variant. Cross-reference the revision history to validate the most recent product specifications before finalizing procurement orders.

Selection Notes

Select this component when TTL-level signal compatibility is required within a CMOS system architecture. The device is suitable for applications demanding high noise immunity and robust electrostatic discharge protection. Ensure the operating environment remains within the specified ambient temperature limits for the selected package type.

Part Context

This part belongs to the 74HCT series of high-speed CMOS logic devices. It is pin-compatible with Low-Power Schottky TTL standards. The device integrates four independent NAND gates into a single integrated circuit, providing a compact solution for complex logic implementations in standard surface-mount packages.

Replacement Considerations

Direct functional equivalents include the 74HC00D/AUJ for CMOS-level inputs or other 74HCT00 variants from Nexperia such as the PW or BQ package options. Verify pinout and electrical characteristics match before substitution.
