SN74S257N TI Multiplexer | 16-PDIP | Quad 2-to-1, 3-State Output

Product Overview

The SN74S257N is a quad 2-to-1 data selector/multiplexer with 3-state outputs from Texas Instruments. It features Schottky-clamped transistors for high speed, typically 10 ns propagation delay. The device selects one of two 4-bit data sources (A or B) based on the select input (S). The outputs are disabled when the output enable (OE) input is high, placing them in a high-impedance state. Operating over 0°C to 70°C, it is ideal for bus-oriented systems.
