SN74HC02PW

Overview

The SN74HC02PW is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and features low static power consumption with a maximum quiescent current of 2 µA. The device provides symmetric output drive capabilities, delivering 5.2mA at both high and low logic levels. It utilizes a 14-TSSOP surface-mount package and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Contains four independent 2-input NOR logic gates in a single integrated circuit
• Operates across a wide supply voltage range from 2V to 6V
• Features Schmitt-trigger-like noise immunity characteristics inherent to the HC series

Applications

• Digital logic signal processing
• General-purpose combinational logic circuits
• Embedded system control interfaces

Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-14 package variant. Confirm RoHS compliance status as manufacturing processes may change. Check for obsolescence notices or PCN documentation regarding assembly site changes. Ensure the source document matches the exact part number to avoid confusion with similar logic families like HCT or AHC.

Selection Notes

Select this component when a quad NOR configuration is required in a compact surface-mount footprint. The HC series offers compatibility with standard CMOS logic levels. Consider the 2V to 6V operating range for flexibility in various power supply environments. Verify that the 5.2mA drive strength meets the load requirements of the connected downstream components.

Part Context

This component belongs to the Texas Instruments SNx4HC00 series of high-speed CMOS logic devices. The '02' designation specifically identifies the NOR gate function, distinct from NAND (00) or NOT (04) variants. It shares the same physical package and pinout structure as other members of the 74HC family, facilitating design reuse across different logic functions.

Replacement Considerations

SN74HC02PWR: Tape and reel version of the same device. 74HC02PW,118: Nexperia equivalent in the same package.
