TIL196ASM

Overview

The TIL196ASM is a quad optocoupler manufactured by Isocom Components, designed for AC and DC input isolation. It features four independent channels with transistor outputs housed in a 16-SMD package. The device provides high-density mounting capabilities for circuit isolation applications.

Feature Summary

• Four independent optical channels for multi-signal isolation
• Transistor output configuration for digital switching
• Supports both AC and DC input signal types
• Surface-mount design for compact PCB integration

Applications

• Multi-channel data bus isolation
• Industrial control system signal interfacing
• Power supply feedback loop isolation
• Microcontroller peripheral isolation

Procurement Notes

Verify the specific suffix ASM against official Isocom documentation to confirm pinout and package dimensions. Ensure the selected variant matches the required surface-mount footprint and thermal characteristics for the target application environment.

Selection Notes

Select this component when multiple isolated channels are required in a single package. Consider the transistor output speed and current transfer ratio relative to the load requirements. Verify compatibility with the intended AC or DC input drive levels before implementation.

Part Context

The TIL196 series belongs to Isocom's family of high-density AC input phototransistor optically coupled isolators. These devices utilize inverse-connected infrared LEDs to facilitate reliable isolation across multiple channels within a compact form factor suitable for modern electronic assemblies.

Replacement Considerations

Cross-reference with other quad optocouplers offering similar isolation voltage and channel count. Verify that alternative parts support the same 16-pin SMD package and provide comparable current transfer ratios for direct functional substitution.
