MC74VHCT257A Description
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 mon select (S) and enable (OE) inputs.
