TLP280-4

The TLP280-4 is a photocoupler, also known as an optocoupler, manufactured by Toshiba. It is designed to provide electrical isolation between input and output circuits while transmitting electrical signals. This isolation is crucial in preventing high voltages or transient spikes from affecting sensitive components within a system.
The TLP280-4 consists of four channels, each comprising an infrared LED and a phototransistor. When the LED is activated by an input signal, it emits infrared light that is detected by the phototransistor, which in turn conducts and transmits the signal to the output side. This setup effectively isolates the input from the output, providing a safe signal transfer mechanism.
The device is housed in a compact DIP (Dual In-line Package) and is known for its high isolation voltage, typically up to 2,500 Vrms. It is commonly used in applications such as signal isolation in microcontrollers, power supply feedback, and data communication interfaces. The TLP280-4's multi-channel design makes it a versatile and efficient choice for systems requiring multiple isolated signal paths.

These features make the TLP280-4 suitable for applications like digital logic interfaces, power supply feedback control, and signal isolation in various electronic devices.

The TLP280-4 is a quad phototransistor optocoupler, which means it contains four channels of optically coupled pairs of light-emitting diodes (LEDs) and phototransistors. It is typically used for signal isolation and interfacing between circuits of different voltage levels, providing electrical isolation while allowing signal transmission.
The TLP280-4 comes in a 16-pin package. Each channel consists of an input LED and an output phototransistor. The pin configuration is as follows:
- Pins 1, 3, 5, and 7 are the anodes of the input LEDs for channels 1 to 4, respectively.
- Pins 2, 4, 6, and 8 are the cathodes of the input LEDs for channels 1 to 4, respectively.
- Pins 9, 11, 13, and 15 are the collectors of the output phototransistors for channels 1 to 4, respectively.
- Pins 10, 12, 14, and 16 are the emitters of the output phototransistors for channels 1 to 4, respectively.
This configuration allows the device to perform four channels of isolation in a single package, commonly used in applications like microcontroller interfacing, power supply circuits, and communication systems.
