OE19

I

Active high control logic input. Pulling this pin high connects the A side to B side of all switches.
VCC20

P

Positive power supply. This pin is the most positive power-supply potential. For reliable operation, connect a decoupling capacitor ranging from 0.1 µF to 10 µF between VDD and GND.

(1) I = input, O = output, I/O = input and ouput, P = power.
