Description
The PI5A3158 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 PI5A3158 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, tolerates input drive signals up to 5.5V,
independent of supply voltage.
