FSAL200 Wide Bandwidth Quad 2:1 Analog Multiplexer/Demultiplexer Switch
FSAL200
Wide Bandwidth Quad 2:1 Analog
Multiplexer/Demultiplexer Switch
General Description
The Fairchild Switch FSAL200 is a rail-to-rail quad 2:1
high-speed CMOS TTL-compatible analog multiplexer/
demultiplexer 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.
Features
■ Typical 6Ω switch connection between two ports
■ Minimal propagation delay through the switch
■ Low I
CC
■ Zero bounce in flow-through mode
■ Control inputs compatible with TTL level
■ Rail-to-rail signal handling
■ Low insertion loss
■ Route communications signals including:
10/100 Ethernet
USB1.1
100VG-AnyLAN
Token Ring 4/16 Mbps
ATM25
SONET OCI 51.8 Mbps
T1/E1
