SN74AS258N TI Multiplexer | 16-PDIP | Quad 2-to-1, 3-State Outputs

Product Overview

The SN74AS258N from Texas Instruments is a high-speed quad 2-to-1 line data selector/multiplexer with 3-state outputs. It features Schottky-clamped transistors for enhanced performance and is designed for memory and peripheral interfacing, as well as bus-oriented systems. The device selects one of two 4-bit data sources (A or B) based on the state of the select input (S). The outputs are disabled when the output-enable (OE) input is high, providing high-impedance states for bus sharing.
