MC74VHCT257A - Quad 2-Channel Multiplexer

MC74VHCT257A Quad 2-Channel Multiplexer with 3-State Outputs The MC74VHCT257A is an advanced high speed CMOS quad 2 channel multiplexer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. It consists of four 2 input digital multiplexers with common select (S) and enable (OE) inputs. When (OE) is held High, selection of data is inhibited and all the outputs go Low. .
