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 and 5.5 Volts. The device exhibits extremely low R
ON
and
adds nearly zero propagation delay. The device adds no noise or
ground bounce to the system.
