74FST3245  
8-Bit Bus Switch  
The ON Semiconductor 74FST3245 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. Port A is connected to Port B  
when OE is low. If OE is high, the switch is high Z.
