The DIODES™ PI5A23157 is a Dual SPDT Analog Switch. The device can be used as an analog switch or as a low-delay bus switch, and has a wide operating power supply voltage, 1.65V to 5.5V.

Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching.
