NOTES

1. PINS LABELED NC CAN BE ALLOWED

TO FLOAT, BUT IT IS BETTER TO

CONNECT THESE PINS TO GROUND.

AVOID ROUTING HIGH SPEED SIGNALS

THROUGH THESE PINS BECAUSE NOISE

COUPLING MAY RESULT.

NC

This pin is not connected internally (see Figure 3).

Ground 1. Ground reference for isolator primary. Pin 2 and Pin 10 are internally connected, and it is recommended

that all pins be connected to a common ground.

8

PDIS

the power supply enters a low power standby mode.

9

Primary Supply Voltage, 3.0 V to 5.5 V.

Ground Reference for Isolator Side 2. Pin 19 and Pin 11 are internally connected, and it is recommended that all pins

be connected to a common ground.

12

Secondary Supply Voltage Output for External Loads, 3.15 V to 5.5 V depending on voltage divider connected
