The is a single-pole single-throw SPST quad Analog Switch features two input/output terminals nY and nZ and an active HIGH enable input nE. When nE is LOW, the analog switch is turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
