Pinout
- Pin Count: 4 pins.
- Function:
- Pin 1: Anode of the LED. This is where the input signal is provided to activate the LED within the optocoupler.
- Pin 2: Cathode of the LED. Completes the circuit for the LED, allowing current to flow through when a signal is present.
- Pin 3: Emitter of the phototransistor. This is one of the output connections, allowing the signal to be transferred to the output side.
- Pin 4: Collector of the phototransistor. This is the other output connection, usually connected to a load or circuit that needs to be isolated from the input side.
The primary function of the TLP293 is to transfer electrical signals between two isolated circuits using light, providing electrical isolation between its input and output.
