Datasheet (EN) 1.1

Non-inverting Receiver Input

Isolated Power Supply Output. This pin must be connected externally to V_ISOIN. It is recommended

this pin have a 0.1 μF and 10μF capacitor to GND₂(Pin20). Connect this pin through a ferrite bead

and short trace length to V_ISOINfor operation.

V_ISOOUT

GND₂

Ground 2, the ground reference for Isolator Side 2

VISO output voltage select, V_ISOOUT=5V when SEL is floating or connect to V_ISOIN, V_ISOOUT=3.3V

when SEL short to GND₂

Isolated power supply Input. This pin must be connected externally to V_ISOOUT. It is

recommended this pin have a 0.1 μF capacitor to GND₂. Connect this pin to V_ISOOUTthrough a

ferrite bead and short trace length for operation.

SEL

V_ISOIN

Non-inverting Driver Output. When the driver is disabled, or when VDDL is powered down, Pin Y

is put into a high impedance state to avoid overloading the bus.
