MC74VHC257
Quad 2-Channel Multiplexer with 3-State Outputs
The MC74VHC257 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...
