SN74LS125AN TI Quad Bus Buffer | 14-PDIP | 3-State Outputs, Low Power

Product Overview

The SN74LS125AN is a high-performance quad bus buffer gate from Texas Instruments, featuring independent 3-state outputs. Each buffer has a separate output enable input (active-low) that controls the output state. When the output enable is low, the output follows the input; when high, the output is in a high-impedance state, allowing multiple outputs to be connected to a common bus. The device is designed for TTL logic systems and operates from a 5V supply. It is housed in a 14-pin PDIP package, making it suitable for through-hole PCB assembly.
