Notes
- The device contains eight bidirectional analog switches.
- The analog inputs/outputs can swing between VCC and VEE.
- When E is high, all switches are in a high-impedance off state.
Note: Data is maintained by an independent source and accuracy is not guaranteed. Check with the manufacturer's datasheet for up-to-date information.
