General Description
The FSA66 is a ultra high-speed (UHS) CMOS compati-
ble Single-Pole/Single-Throw (SPST) analog switch. The
low On Resistance (R
ON
) of the switch allows input to be
connected to output with minimal propagation delay and
without generating additional ground bounce noise. The
device is organized as a 1-bit switch with a switch enable
(OE) signal. When OE is HIGH, the switch is on and Port
A is connected to Port B. When OE is LOW, the switch is
open and a high-impedance state exists between the two
ports.
