74FST3345  
8−Bit Bus Switch  
The ON Semiconductor 74FST3345 is an 8−bit, high performance  
switch. The device is CMOS TTL compatible when operating between  
4 and 5.5 Volts. The device exhibits extremely low R  
and adds  
ON  
nearly zero propagation delay. The device adds no noise or ground  
bounce to the system.  
The device consists of an 8−bit switch with two Output/Enable pins  
(OE and OE).
