Table 9. ADG732 Pin Function Description
Pin No. Mnemonic Description
1 to 12, 45 to 48 S16 to S1 Source Terminal. This pin may be an input or output.
13, 14 V
DD
Most Positive Power Supply Potential.
15 to 19 A0 to A4 Logic Control Inputs.
20
CS
Chip Select Pin.
CS
is active low.
WR
Write Pin. When
is low, the logic control inputs (A0 to A4) control which state the switches are in. On
the rising edge of
WR
, the logic control input data is latched.
22
EN
Active Low, Digital Input. When this pin is high, the device is disabled and all switches are off. When this
pin is low, the Ax logic control inputs determine the on switches. The
EN
input signal is not latched by
WR
.
23 GND Ground (0 V) Reference.
24 V
SS
Most Negative Power Supply in a Dual-Supply Application. In single-supply applications, connect this pin
to GND.
25 to 40 S17 to S32 Source Terminal. This pin may be an input or output.
41, 42, 44 NIC Not Internally Connected. Do not connect to this pin.
43 D Drain Terminal. This pin may be an input or output.
EPAD Exposed Pad. The exposed pad must be connected to GND.
