Description
The PI5A3158 is a dual high-bandwidth, fast single-pole doublethrow (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 range, 1.65V to 5.5V, the PI5A3158 has a maximum On-Resistance of 12 at 1.65V, 9 at 2.3V & 6 at 4.5V. Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching. The control input, S, tolerates input drive signals up to 5.5V, independent of supply voltage.

Notes: 1. This product has always shipped as only a lead free product, but since it was introduced prior to Pericom's strategy of adding an E to all Green/ Lead free parts many customers order it without the E suffix. Please migrate new designs and qualification to include the E suffix. Pericom at this point in time will continue to offer devices marked both ways, but may at a later date eliminate the non-E part number. 2.
