TIL191ASM

Overview

The TIL191ASM is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a high-density DIP-4 package with transistor output. The device utilizes an infrared LED coupled to an NPN silicon phototransistor for signal isolation. Key electrical parameters include a maximum forward voltage of 1.4V and a typical rise/fall time of 100μs. It supports a maximum input current of 50mA and offers an isolation voltage of 5300Vrms. The unit operates within a temperature range of -55°C to 100°C and holds UL standard certification.

Feature Summary

Integrates an infrared light emitting diode with an NPN silicon phototransistor for optical signal transmission
Provides high-voltage electrical isolation between input and output circuits
Designed for high-density mounting applications using a compact four-pin configuration

Applications

General purpose signal isolation in electronic circuits
Interface between microprocessors and peripheral devices
Switching applications requiring galvanic isolation

Procurement Notes

Verify the specific suffix 'ASM' against official manufacturer documentation to confirm pinout, package dimensions, and tape/reel specifications. Ensure that the selected variant matches the required thermal and electrical ratings for the target application environment. Cross-reference datasheet revisions to confirm compliance with current safety standards.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed is required. The 100μs switching time suits general-purpose applications rather than high-speed data transmission. Consider the 5300Vrms isolation rating for safety-critical interfaces. Verify that the 4-pin DIP form factor fits the available PCB space constraints.

Part Context

This part belongs to the TIL191 series of optocouplers from Isocom Components 2004 LTD. The series typically includes variants such as TIL191ASMT and TIL197. These devices are designed to provide reliable isolation in compact packages, serving as a bridge between low-power control logic and higher-power or noisy load circuits.
