SN74HCT257DR TI Multiplexer | 16-SOIC | 4-Channel, 2-Input, TTL Compatible

Product Overview

The SN74HCT257DR from Texas Instruments is a high-speed CMOS quad 2-input multiplexer with 3-state outputs. It selects one of two 4-bit data sources based on the state of the select input (S). The device features TTL-compatible inputs and outputs, making it ideal for interfacing with TTL logic families. Operating from a 4.5V to 5.5V supply, it offers low power consumption and high noise immunity. The 16-SOIC package is suitable for surface-mount applications.
