Descriptions:

The SN74S38DR is a quad 2-input NAND buffer with open-collector outputs, designed for TTL (Transistor-Transistor Logic) applications. It is part of Texas Instruments' 74S series, which offers Schottky-clamped transistors for improved switching speed. The open-collector outputs allow for wired-OR connections and interfacing with higher voltage systems.

Features:

  • Schottky-clamped for high speed
  • Open-collector outputs for bus driving and wired-OR applications
  • Wide operating voltage range (4.75V to 5.25V)
  • Low power consumption (compared to standard TTL)
  • Surface-mount SOIC-14 package
  • Industrial standard pinout
  • Compatible with most TTL logic families

This part is commonly used in digital logic circuits, bus interfaces, and signal buffering applications.
