SN74HC02PWT

Overview

The SN74HC02PWT is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the HC logic series and utilizes silicon gate CMOS technology. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a propagation delay of 8 ns, a low-level output current of 5.2 mA, and a high-level output current of -5.2 mA. It supports an operating temperature range from -40°C to +125°C. The component is housed in a TSSOP-14 package.

Feature Summary

• Contains four independent 2-input NOR gates for complex logic implementation
• Utilizes silicon gate CMOS technology for high-speed operation
• Provides buffered outputs with high noise immunity

Applications

• General-purpose digital logic circuits
• Signal processing applications requiring NOR logic functions
• Industrial control systems operating within extended temperature ranges

Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-14 package and 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the exact functional requirements and environmental specifications defined in the datasheet.

Selection Notes

Select this component when a quadruple 2-input NOR function is required in a compact surface-mount format. The HC series offers a balance of speed and power consumption suitable for general digital applications. Verify that the 2 V to 6 V supply voltage range aligns with the system design constraints and that the TSSOP-14 footprint fits the PCB layout.

Part Context

This component is part of the SNx4HC02 family of quadruple 2-input positive-NOR gates. It shares logical functionality with other variants in the series but differs in packaging and manufacturing revisions. The HC designation indicates High-speed CMOS technology, distinguishing it from standard or low-power variants within the broader 74xx logic ecosystem.

Replacement Considerations

Compatible substitutes include SN74HC02DR and SN74HC02DWR, which offer identical logical functions in alternative SMD packages such as SOIC-14.
