Pin Name
Description
1
NC No connect.
2
ANODE Anode of LED emulator. V_O follows the signal applied to this input with respect to the
CATHODE input.
3 CATHODE Cathode of LED emulator. V_O follows the signal applied to ANODE with respect to this input.
4
NC No connect.
5
V_SS External MOSFET source connection and ground reference for V_DD. This terminal is typically
connected to ground but may be tied to a negative or positive voltage.
6
V_O
Output signal. Pins 6 and 7 are connected together internally.
7
V_O
Output signal. Pins 6 and 7 are connected together internally.
8
V_DD Output-side power supply input referenced to V_SS (24 V max).
*Note: No Connect. These pins are not internally connected.
