Pin Function Specifications:

Below is a detai LED description of the pin functions for a typical 16-pin ACPL-C790-500E optocoupler.

Pin Number Pin Name Pin Function Description 1 Anode (Pin A) Anode of the LED element in the optocoupler; provides current to the LED during operation. 2 Cathode (Pin K) Cathode of the LED element; current flows through the LED from anode to cathode for activation. 3 NC (No Connect) No electrical connection. This pin is unused and should be left floating. 4 NC (No Connect) No electrical connection. This pin is unused and should be left floating. 5 Collector (Pin C) Collector of the photo transistor ; it receives the signal from the LED after it has been optically isolated. 6 Base (Pin B) Base of the phototransistor; controls the current flow between the collector and emitter. 7 Emitter (Pin E) Emitter of the phototransistor; it is the output pin that will provide the transferred signal to the load. 8 NC (No Connect) No electrical connection. This pin is unused and should be left floating. 9 NC (No Connect) No electrical connection. This pin is unused and should be left floating. 10 NC (No Connect) No electrical connection. This pin is unused and should be left floating. 11 NC (No Connect) No electrical connection. This pin is unused and should be left floating. 12 NC (No Connect) No electrical connection. This pin is unused and should be left floating. 13 NC (No Connect) No electrical connection. This pin is unused and should be left floating. 14 NC (No Connect) No electrical connection. This pin is unused and should be left floating. 15 Vcc (Power Supply) Positive supply voltage for the phototransistor side; typically connected to the power rail of the system. 16 Ground (GND) Ground or return for the optocoupler's power supply circuit.

(Note: "NC" pins are typically unused and should be left floating or disconnected during PCB design.)
