Description
The FST3345 switch provides eight-bits of high-speed
CMOS TTL-compatible bus switching. 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 an eight-bit switch with dual
output enable inputs (OE and /OE). When /OE is LOW
or OE is HIGH, the switch is ON and port A is
connected to port B. When /OE is HIGH, and OE is
LOW, the switch is OPEN and a high-impedance state
exists between the two ports.
