74HCT02PW/S400,118

Overview

The Nexperia 74HCT02PW/S400,118 is a quad 2-input NOR gate from the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input levels. The device includes clamp diodes on all inputs, allowing interface with voltages exceeding VCC via current-limiting resistors. It provides high noise immunity and low power dissipation typical of CMOS technology.

Feature Summary

• Provides four independent 2-input NOR logic functions
• Features TTL-compatible input voltage levels for direct interfacing
• Includes input clamp diodes to support operation above VCC

Applications

• General-purpose digital logic processing
• Signal gating and control circuits
• Automotive body control modules

Procurement Notes

Verify the specific suffix S400 against official Nexperia documentation to confirm package variant and tape-and-reel specifications. Ensure the ordering code matches the required automotive qualification grade and temperature range before procurement.

Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS performance characteristics. It serves as a suitable alternative to standard HC series devices in systems requiring robust noise immunity and defined input thresholds.

Part Context

This part belongs to the Nexperia 74HCT logic portfolio, designed for automotive and industrial applications. It shares functional similarities with other HCT NOR gates but is distinguished by its specific packaging and automotive-grade reliability standards.

Replacement Considerations

Direct replacements include the 74HCT02DB or 74HCT02BQ from Nexperia, provided pinout and electrical parameters remain compatible with the existing design constraints.
