TIL196BG

Overview

The TIL196BG is a quad optocoupler featuring four independent channels within a single 16-pin DIP package. It utilizes an AC input LED configuration with two infrared LEDs connected in inverse parallel to enable direct drive from alternating current sources without external rectification. The output side employs phototransistors for signal isolation. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise time of 100µs, and a typical fall time of 100µs. The device supports a maximum input current of 50mA and provides an isolation voltage of 5300Vrms. Current transfer ratios range from 500% minimum to 7500% maximum.

Feature Summary

• Four-channel architecture housed in a high-density 16-pin dual in-line package
• AC input capability via inverse-parallel infrared LED arrangement
• Phototransistor output stage for digital signal isolation
• High isolation voltage rating for robust circuit protection

Applications

• Industrial control systems requiring multi-channel isolation
• Solid-state relay driver circuits
• Microprocessor interface modules
• Power supply feedback loops

Procurement Notes

Verify the specific suffix designation against official Isocom documentation to confirm pinout compatibility and packaging type. Ensure that the AC input requirement aligns with the internal LED structure. Confirm that the operating temperature range meets system specifications. Cross-reference the isolation voltage ratings with safety standards applicable to the end equipment. Validate that the current transfer ratio meets the load requirements of the destination circuit.

Selection Notes

Select this component when multiple isolated channels are required in a compact footprint. The AC input feature simplifies circuit design by eliminating external diodes for rectification. Consider the 100µs switching speed for applications not requiring high-frequency operation. Evaluate the 5300Vrms isolation barrier for safety-critical interfaces. Compare the current transfer ratio against the driving capability of the source logic.
