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 positive voltage.
6
V_O
Output signal.
7
NC* No connect.
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.
