SN74F38D

Overview

The SN74F38D is a Texas Instruments logic gate integrated circuit housed in a 14-pin Small Outline Integrated Circuit (SOIC) package. It contains four independent 2-input NAND buffer gates with open-collector outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range from 0 °C to 70 °C. At a supply voltage of 5 V, the typical propagation delay is 9.6 ns.

Feature Summary

• Contains four independent 2-input NAND buffer gates
• Features open-collector outputs requiring external pullup resistors
• Supports active-low wired-OR or active-high wired-AND functions when connected together

Applications

• Implementing active-low wired-OR logic functions
• Implementing active-high wired-AND logic functions
• Generating higher output high-level voltages

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current Package Option Addendum to confirm status and packaging. Confirm that the specific variant matches the required SOIC package dimensions and lead finish specifications for your assembly process.

Selection Notes

Select this component when four independent 2-input NAND gates are required in a surface-mount configuration. Ensure the design accommodates the open-collector nature of the outputs by including appropriate external pullup resistors. Verify that the 0 °C to 70 °C commercial temperature range meets the application requirements.

Part Context

This part belongs to the Texas Instruments 74F series of logic devices. The 'D' suffix specifically denotes the 14-pin SOIC plastic small-outline package. Other variants in the family include the SN74F38N for through-hole DIP packages and the SN74F38DR for tape-and-reel surface-mount configurations.
