Description

The PI5A3159 is a 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 range, 1.8V to 5.5V, the PI5A3159 has a maximum On-Resistance of 4 at 1.8V, 2.4 at 2.3V & 1 at 4.5V.

Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching.Control input, S, tolerates input drive signals up to 5.5V, independent of supply voltage.PI5A3159 is a low On-Resistance replacement for the PI5A3157 and NC7SB3157.
