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 GND Ground reference for V
DD
. This terminal is typically connected to ground but may be tied to a negative or pos-
itive voltage.
6 V
O
Output signal.
7 EN Output enable. Tied to V
DD
to enable output.
8 V
DD
Output-side power supply input referenced to GND (5.5 V max).
Note: No Connect. These pins are not internally connected. To maximize CMTI performance, these pins should be connected to the
ground plane.
