Description
1
ANODE Anode of LED emulator. VO follows the signal applied to this input with respect to the
CATHODE input.
2
NC No connect.
3 CATHODE Cathode of LED emulator. VO follows the signal applied to ANODE with respect to this input.
4
GND 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.
5
VO
Output signal.
6
VDD Output-side power supply input referenced to GND (30 V max).
*Note: No Connect. These pins are not internally connected. To maximize CMTI performance, these pins should be
connected to the ground plane.
