SN74AS257DR TI Multiplexer | 16-SOIC | Quad 2-Input, Non-Inverting

Product Overview

The SN74AS257DR from Texas Instruments is a high-speed quad 2-input multiplexer with non-inverting outputs. It selects one of two data sources per channel based on the select input (A/B). The device features 3-state outputs for bus-oriented applications, enabling multiple devices to share a common data bus. Housed in a 16-pin SOIC package, it is designed for surface-mount technology and operates over a wide temperature range.
