TC74HC257AP Quad 2-Channel Multiplexer

TC74HC257AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC257AP, TC74HC257AF Quad 2-Channel Multiplexer (3-state) The TC74HC257A is high speed CMOS MULTIPLEXER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. It is composed of four independent 2-channel multiplexers with common SELECT and OUTPUT ENABLE ( OE ). If OE is set low, the outputs are held in a high-imp.
