______________________________________________________________Pin Description
Note: NO_ and COM_ pins are identical and interchangeable. Either may be considered as an input or an output; signals pass
equally well in either direction.
NAME FUNCTION
1 SCLK Serial Clock Digital Input
2 V+ Positive Analog Supply Voltage Input
PIN
3 DIN Serial Data Digital Input
5, 7, 9, 11, 14, 16, 18, 20 NO0–NO7 Normally Open Analog Switches 0–7
6, 8, 10, 12, 13, 15, 17, 19 COM0–COM7 Common Analog Switches 0–7
21 V- Negative Analog Supply Voltage Input. Connect to GND for single-supply operation
22 DOUT Serial Data Digital Output. (High is sourced from V+.)
23 RESET
Reset Input. Connect to digital (logic) supply (or V+). Drive low to set all switch-
es off and set internal shift registers to 0.
24 CS Chip-Select Digital Input (Figure 1)
4 GND
Ground. Connect to digital ground. (Analog signals have no ground reference;
they are limited to V+ and V-.)
