Description
The PI5A3158B is a dual 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 PI5A3158B has a maximum
ON resistance of 12-ohms at 1.65V, 9-ohms at 2.3V &
6-ohms 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.
