FST3125
4-Bit Bus Switch
The ON Semiconductor FST3125 is a quad, high performance
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.
The device consists of four independent 1bit switches with
separate Output/Enable (OE
) pins. Port A is connected to Port B when
OE
is low. If OE is high, the switch is high Z.
