74HCT02PW,118

Overview

The 74HCT02PW,118 is a quad 2-input NOR gate manufactured by Nexperia USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input levels. The device utilizes a 14-lead TSSOP plastic thin shrink small outline package (SOT402-1). Static characteristics include an input leakage current maximum of ±1 µA at 5.5 V and a supply current maximum of 40 µA across the operating temperature range of -40 °C to +125 °C.

Feature Summary

• Provides four independent 2-input NOR logic functions in a single integrated circuit
• Features clamp diodes on inputs to allow interfacing with voltages exceeding VCC using current limiting resistors
• Complies with JEDEC standards JESD8C and JESD7A for CMOS low power dissipation and high noise immunity
• Includes electrostatic discharge protection rated at over 2000 V for Human Body Model and over 1000 V for Charged Device Model

Applications

• Digital logic circuits requiring NOR functionality
• Signal processing systems utilizing TTL-compatible interfaces
• General-purpose electronic equipment operating within specified voltage and temperature limits

Procurement Notes

Verify that the specific part number matches the required HCT logic family specifications rather than HC variants. Confirm the TSSOP14 package type aligns with PCB footprint requirements. Ensure compliance with RoHS3 directives and REACH regulations as stated in the product documentation before finalizing procurement orders.

Selection Notes

Select this component when TTL-level input compatibility is required alongside CMOS output performance. The wide operating temperature range supports industrial applications. Consider the TSSOP package dimensions for space-constrained designs. Verify that the supply voltage remains strictly within the 4.5 V to 5.5 V recommended operating conditions to ensure proper logic level translation and signal integrity.

Part Context

This component belongs to the 74HC/HCT02 series of quad 2-input NOR gates produced by Nexperia. It shares functional similarities with other members of the 74xx logic family but is distinguished by its HCT input structure designed for direct interfacing with TTL devices. The PW suffix indicates the specific TSSOP14 packaging configuration used for surface-mount assembly.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent 74HCT02 parts in TSSOP14 packages. Verify pinout compatibility and electrical parameter alignment, particularly regarding propagation delay and output drive capability, before substituting.
