Description and Introduction

Quad 2-Input NAND Buffer with Open-Collector Outputs The 74LS38 is a quad 2-input NAND buffer with open-collector outputs, manufactured by Texas Instruments. It is part of the 74LS series of logic ICs. Key specifications include:

- **Logic Function**: Quad 2-input NAND buffer
- **Output Type**: Open-collector
- **Supply Voltage (VCC)**: 4.75V to 5.25V (nominal 5V)
- **High-Level Output Current (IOH)**: -0.4 mA
- **Low-Level Output Current (IOL)**: 8 mA
- **Propagation Delay**: Typically 15 ns
- **Operating Temperature Range**: 0°C to 70°C
- **Package Options**: 14-pin DIP, SOIC, and other surface-mount packages

The open-collector outputs allow for wired-AND connections and interfacing with higher voltage or current devices. It is commonly used in digital logic circuits for buffering and signal inversion.
