Pin No. Mnemonic Description

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

VOC

Logic Output C.

6

VOD

Logic Output D.

7

VE1

Output Enable 1. Active high logic input. VOC and VOD outputs are enabled when VE1 is high or disconnected.

VOC and VOD outputs are 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 and VOB outputs are enabled when VE2 is high or disconnected.

VOA and VOB 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

VIC

Logic Input 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 2, 2.7 V to 5.5 V.
