74FST3383
10−Bit Low Power
Bus Exchange
The ON Semiconductor 74FST3383 is a 10−bit low power bus
exchange. The device is CMOS TTL compatible when operating
between 4 and 5.5 Volts. The device exhibits extremely low R and
adds nearly zero propagation delay. The device adds no noise or
ground bounce to the system.
