ADG441 Implementation

I am having trouble getting the ADG441 to work properly and want to confirm that my setup is correct. To test the chip, I made the following connections:

analog ground/0v to GND

-9v to Vss

+9v to Vdd

0.5v 1KHz sine wave to S1

Logic input of 0v or 5v to IN1

No matter if I give IN1 0v or 5v, the signal received at D1 is always the same signal connected to S1. What am I doing wrong in my setup that is preventing the switch from opening?
