FSAL200
Quad 2:1 Multiplexer/Demultiplexer
Wide Bandwidth LAN Switch
General Description
The Fairchild Switch FSAL200 is a rail-to-rail quad 2:1
high-speed CMOS TTL-compatible multiplexer/demulti-
plexer LAN switch. The low On Resistance of the switch
allows inputs to be connected to outputs without adding
propagation delay or generating additional ground bounce
noise.
When OE is LOW, the select pin connects the A Port to the
selected B Port output. When OE is HIGH, the switch is
OPEN and a high-impedance state exists between the two
ports.
