74FST3861
10−Bit Bus Switch
The ON Semiconductor 74FST3861 is a 10−bit, high performance
bus switch. The device is CMOS TTL compatible when operating
between 4.0 and 5.5 Volts. The device exhibits extremely low R and
ON
adds nearly zero propagation delay. The device adds no noise or
ground bounce to the system.
