Pin Descriptions
EQUIVALENT
PIN NUMBER PIN NAME CIRCUIT
DESCRIPTION
1, 3, 7
NIC
Not Internally Connected; it is recommended this pin be tied to ground to minimize crosstalk
2
IN0
Circuit 1 Input for channel 0
4
IN1
Circuit 1 Input for channel 1
5
GND
Circuit 4 Ground pin
6
IN2
Circuit 1 Input for channel 2
8
IN3
Circuit 1 Input for channel 3
9
S0
Circuit 2 Channel selection pin LSB (binary logic code)
10
S1
Circuit 2 Channel selection pin MSB (binary logic code)

Circuit 3 Output
14
IN-
Circuit 1 Inverting input of output amplifier
15
HIZ
Circuit 2 Output disable (active high); there are internal pull-down resistors, so the device will be active with
no connection; “HI” puts the output in high impedance state
16
ENABLE
Circuit 2 Device enable (active low); there are internal pull-down resistors, so the device will be active with
no connection; "HI" puts device into power-down mode
