Description
Fairchild switch FST3125 provides four high-speed
CMOS TTL-compatible bus switches. The low on
resistance of the switch allows inputs to be connected
to outputs without adding propagation delay or
generating additional ground bounce noise.
The device is organized as four one1-bit switches with
separate /OE inputs. When /OE is LOW, the switch is
ON and port A is connected to port B. When /OE is
HIGH, the switch is OPEN and a high-impedance state
exists between the two ports.
