Table 11. ADuM5401 Pin Function Descriptions

Pin No. Mnemonic Description

V_DD1

Primary Supply Voltage, 3.0 V to 5.5 V.

2, 8

GND₁

Ground 1. Ground reference for isolator primary. Pin 2 and Pin 8 are internally connected, and it is recommended that both

pins be connected to a common ground.

V_IA

Logic Input A.

V_IB

Logic Input B.

V_IC

Logic Input C.

V_OD

Logic Output D.

Make no connection to this pin.

9, 15

GND_ISO

Ground Reference for Isolator Side 2. Pin 9 and Pin 15 are internally connected, and it is recommended that both pins be

connected to a common ground.

V_SEL

Output Voltage Selection. When V_SEL= V_ISO, the V_ISOsetpoint is 5.0 V. When V_SEL= GND_ISO, the V_ISOsetpoint is 3.3 V.

V_DD1and V_ISOvoltages must be in the same operating range to guarantee proper operation of the data channels.

V_ID

Logic Input D.

Logic Output C.

Logic Output B.

Logic Output A.

V_OC

V_OB

V_OA

V_ISO

Secondary Supply Voltage Output for External Loads, 3.3 V (V_SELLow) or 5.0 V (V_SELHigh). V_DD1and V_ISOvoltages must be

in the same operating range to guarantee proper operation of the data channels.
