Quad 2-Channel Multiplexer (3-state)
The TC74VHC257 is an advanced high speed CMOS MULTIPLEXER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
It is posed of four independent 2-channel multiplexers with mon SELECT and OUTPUT ENABLE ( OE ).
If OE is set low, the outputs are held in a high-impedance state. When SELECT is set low, “A” data inputs are enabled.
Conversely, when SELECT is high, “B” data inputs are enabled.
