PI3A268C

Description

The 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 2.5V to 4.3V, the PI3A268C processes a low on-resistance and distortion. Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching.

The 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.
