SN74F02DRE4

Overview

The SN74F02DRE4 is a quadruple 2-input positive-NOR gate from the Texas Instruments 74F series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range of 0°C to 70°C. The device features low-level output current of 20 mA and high-level output current of -1 mA. Switching characteristics at VCC = 5 V with CL = 50 pF include propagation delays (tPLH) ranging from 1.7 ns to 6.5 ns and (tPHL) from 1 ns to 5.3 ns.

Feature Summary

• Contains four independent 2-input NOR gates performing Boolean functions Y = A + B or Y = A • B in positive logic.

Applications

• General-purpose digital logic circuits requiring NOR functionality.

Procurement Notes

Verify the specific ordering suffix 'E4' against the latest Package Option Addendum to confirm lead finish, RoHS status, and moisture sensitivity level. Confirm that the SOIC package designation matches the required board layout dimensions and thermal specifications for the target application environment.

Selection Notes

Select this component when utilizing the standard 74F logic family characteristics for NOR operations. Ensure the design accommodates the specified 4.5 V to 5.5 V supply voltage range and the 0°C to 70°C operating temperature limits defined for the SN74 variant.

Part Context

This part belongs to the SN54F02/SN74F02 family of quadruple 2-input positive-NOR gates. The SN74F02 variant is characterized for commercial temperature ranges, distinguishing it from the SN54F02 which supports military temperature ranges. The device is available in multiple package options including SOIC, PDIP, and ceramic carriers.
