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

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).
