74HCT02PW,112

Overview

The Nexperia 74HCT02PW,112 is a quad 2-input NOR gate in the 74HCT logic family. It operates on a supply voltage of 4.5 V to 5.5 V and features TTL input levels. The device provides four independent NOR gates within a 14-lead TSSOP package (SOT402-1). It includes input clamp diodes for interfacing with voltages exceeding VCC. Static characteristics specify low power dissipation and high noise immunity, while dynamic performance indicates propagation delays up to 29 ns at 4.5 V.

Feature Summary

• Quad 2-input NOR logic function
• TTL compatible input levels
• Input clamp diodes for overvoltage protection
• High ESD protection capabilities

Applications

• Digital logic signal processing
• Boolean logic circuit implementation
• General-purpose digital systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required TSSOP14 package variant. Ensure compliance with RoHS3 directives and check for any recent product change notices affecting specifications or availability status before finalizing procurement plans.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS output drive capabilities. The 74HCT02PW,112 is suitable for designs needing robust noise immunity and standard NOR functionality. Consider the TSSOP14 package constraints regarding thermal dissipation and board space requirements compared to alternative packages like SO14.

Part Context

This part belongs to the Nexperia 74HCT series, designed for compatibility with Transistor-Transistor Logic (TTL) standards while utilizing Complementary Metal-Oxide Semiconductor technology. The PW,112 designation specifically identifies the Thin Shrink Small Outline Package variant with 14 leads, distinguishing it from other package options available within the same logical family.

Replacement Considerations

SN74HC02DWR by Texas Instruments serves as a pin-compatible alternative offering similar quad NOR gate functionality.
