FUNCTION
Analog Switch Normally Open Input 2
Analog Switch “A” Normally Open Input
Analog Switch Normally Open Input 3
Analog Switch “A” Common
Analog Switch Normally Open Input 1
Analog Switch “A” Normally Closed Input
Inhibit. Connect to GND for normal operation. Connect to logic-level high to turn all
switches off.
Ground. Connect to digital ground (analog signals have no ground reference, but
are limited to V+ and GND).
Logic-Level Address Input (see Truth Tables)
Logic-Level Address Input (see Truth Tables)
Logic-Level Address Input (see Truth Tables)
Analog Switch “B” Normally Closed Input
Analog Switch Normally Open Input 0
Analog Switch “B” Normally Open Input
Analog Switch Common
Analog Switch “A” Common
Positive Analog and Digital Supply-Voltage Input
Note: NO_, NC_, and COM_ analog signal pins are identical and interchangeable. Any may be considered an input or output;
signals pass equally well in both directions.
