10-Bit Low Power
Bus Switch
The ON Semiconductor 74FST3384 is a 10–bit low power 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.
