PI5A3157B

Description

The PI5A3157B 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, 1.65V to 5.5V, the PI5A3157B has a maximum ON resistance of 12Ω at 1.65V, 9 Ω at 2.3V & 6 Ω at 4.5V.

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

The control input, S, is independent of supply voltage.

PI5A3157B is an improved direct replacement for the NC7SB3157.
