ISOCOM TIL193 4-Channel Optocoupler, 5.3kV, DIP-16

The ISOCOM TIL193 is a high-density, 4-channel optocoupler designed for robust electrical isolation in demanding applications. It utilises an infrared LED optically coupled to a high-speed NPN silicon phototransistor, providing a reliable signal path while maintaining excellent electrical separation between input and output circuits. This makes it an essential component for preventing ground loops, voltage spikes, and noise from damaging sensitive equipment.

Featuring a through-hole DIP (Dual In-line Package) with 16 pins, it is easy to integrate into prototype boards and existing circuit designs. A key specification is its high isolation voltage of 5.3kV, ensuring safe operation in environments with significant potential differences. The device offers a forward current (If Max) of 50mA and a minimum Current Transfer Ratio (CTR) of 20%, providing efficient signal transmission.

Key Features & Applications

• High-Density Design: Four independent isolation channels in a single compact package, saving valuable board space.
• Robust Isolation: 5.3kV isolation voltage protects low-voltage circuits from high-voltage transients and noise.
• Wide Compatibility: Part of the extensive TIL191/192/193 series, offering design flexibility and easy sourcing of equivalents.
• Reliable Performance: Collector-emitter voltage (V(br)ceo) of 35V ensures stable operation in various circuit conditions.

This optocoupler is a fundamental building block for ensuring safety and signal integrity in a wide range of electronic systems. Its combination of multiple channels, high isolation, and a standard package makes it a versatile and dependable choice for engineers.
