4Bit, 4Port Bus Exchange
Switch
The ON Semiconductor 74FST3400 is a 4bit, 4port bus exchange
switch. The device is CMOS TTL compatible when operating between
4.0 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.
