Description
PI3A268C is a dual, fast single-pole double throw
(SPDT) CMOS switch with negative signal handling
capability at all ports. It can be used as an analog switch
or as a low-delay bus switch. Operating over a wide
power supply voltage ranges from 1.65V to 4.3V,
PI3A268C processes a low on-resistance and distortion.
Break-before-make switching prevents both switches
being enabled simultaneously. This eliminates signal
disruption during switching.
PI3A268C dissipates a very low supply current even
when the control voltage is lower than supply. This
feature suits mobile handset applications by allowing
direct interface with the general-purpose I/Os of
baseband processors with minimal battery consumption.
