Description

1,7 CATHODE Cathode of LED emulator. VO follows the signal applied to ANODE with respect to this

input.

2,3,5,6,8,

10,11,12,

NC* No connect.

ANODE Anode of LED emulator. VO follows the signal applied to this input with respect to the

CATHODE input.

VSS External MOSFET source connection and ground reference for VDD. This terminal is

typically connected to ground but may be tied to a negative or positive voltage.

VO Output signal.

VDD Output-side power supply input referenced to VSS (24 V max).

*Note: No Connect. These pins are not internally connected.
