74FST3257
Quad 2:1 Multiplexer/
Demultiplexer Bus Switch
The ON Semiconductor 74FST3257 is a quad 2:1, high performance
multiplexer/demultiplexer bus switch. The device is CMOS TTL
compatible when operating between 4 and 5.5 Volts. The device
exhibits extremely low R
ON
and adds nearly zero propagation delay.
The device adds no noise or ground bounce to the system.
