SN74AS258DR TI Multiplexer | 16-SOIC | Quad 2-to-1, 3-State Outputs

Product Overview

The SN74AS258DR from Texas Instruments is a high-speed quad 2-to-1 data selector/multiplexer with 3-state outputs. It features Schottky-clamped transistors for enhanced performance, making it ideal for bus-oriented systems. The device selects one of two 4-bit data sources under control of a common select input (S). The 3-state outputs allow connection to a common bus, with an output enable (OE) input that forces all outputs to a high-impedance state when high. The SN74AS258DR is offered in a 16-pin SOIC package, suitable for surface-mount applications.
