Description
Pericom Semiconductor's PI5A4764 is a dual high-bandwidth,
fast single-pole double throw (SPDT) CMOS switch. It can be
used as an analog switch or as a low-delay bus switch. Specified
over a wide operating power supply voltage, 1.65V to 5.5V, the
PI5A4764 has a low On-Resistance of 0.6Ω @ 2.7V.
Break-before-make switching prevents both switches being enabled
simultaneously. This eliminates signal disruption during switching.
The control input, IN_X, tolerates input drive signals up to 6.0V,
independent of supply voltage.
The PI5A4764 shunt switches connected to ground in order to
dissipate capacitance that builds up on the unconnected NC or
NO line. As a result, reduction of popping and clicking sounds is
achieved when switching between audio sources.
