ADuM1400/ADuM1401/ADuM1402
Table 12. ADuM1401 Pin Function Descriptions
Pin
No. Mnemonic Function
1 VDD1
Supply Voltage for Isolator Side 1, 2.7 V to 5.5 V.
2 GND1
Ground 1. Ground reference for isolator Side 1.
3 VIA
Logic Input A.
4 VIB
Logic Input B.
5 VIC
Logic Input C.
6 VOD
Logic Output D.
7 VE1
Output Enable 1. Active high logic input. VOD output is enabled when VE1 is high or disconnected. VOD is disabled when VE1 is low. In
noisy environments, connecting VE1 to an external logic high or low is recommended.
8 GND1
Ground 1. Ground reference for isolator Side 1.
9 GND2
Ground 2. Ground reference for isolator Side 2.
10 VE2
Output Enable 2. Active high logic input. VOA, VOB, and VOC outputs are enabled when VE2 is high or disconnected. VOA, VOB, and VOC
outputs are disabled when VE2 is low. In noisy environments, connecting VE2 to an external logic high or low is recommended.
11 VID
Logic Input D.
12 VOC
Logic Output C.
13 VOB
Logic Output B.
14 VOA
Logic Output A.
15 GND2
Ground 2. Ground reference for isolator Side 2.
16 VDD2
Supply Voltage for Isolator Side 1, 2.7 V to 5.5 V.
