TLP291-4

The TLP291-4 is a quad-channel optocoupler from Toshiba, designed to provide electrical isolation between different parts of a system. Here are its key features:

1. Quad-Channel Configuration: Contains four independent optocoupler channels in a single package, each with its own LED and phototransistor, allowing for simultaneous isolation of multiple signals.
2. Optical Isolation: Provides electrical isolation between input and output, protecting sensitive components from voltage spikes and noise.
3. Phototransistor Output: Each channel features a phototransistor that switches in response to the input LED, enabling digital signal transmission across the isolation barrier.
4. High-Speed Performance: Capable of operating at speeds up to 10 Mbps, suitable for high-speed data communication and signal isolation.
5. Wide Supply Voltage Range: Designed to operate with a wide range of supply voltages, accommodating various system requirements.
6. Compact Package: Available in a 16-pin DIP (Dual In-line Package) format, which is compact and easy to integrate into circuit boards.
7. Applications: Commonly used in digital data transmission systems, power supply isolation, signal isolation in microcontroller interfacing, and general-purpose signal isolation.

The TLP291-4 offers reliable, high-speed electrical isolation with four optocoupler channels in a single package, making it ideal for protecting and isolating signals in complex electronic systems.
