TIL196SM

Overview

The TIL196SM is a high-density, four-channel optocoupler manufactured by Isocom Components. It features a surface-mount DIP-16 package and utilizes photovoltaic output devices. The unit provides an isolation voltage of 5300Vrms between input and output circuits. Designed for AC input applications, the internal structure incorporates two infrared light-emitting diodes connected in inverse parallel configuration to facilitate bidirectional signal transmission.

Feature Summary

• Four independent channels integrated into a single compact package
• Photovoltaic output architecture for zero-bias operation
• Bidirectional AC input capability via inverse-parallel LED configuration

Applications

• High-density digital isolation interfaces
• AC signal switching and detection circuits
• Multi-channel data acquisition systems

Procurement Notes

Verify the specific suffix 'SM' confirms the surface-mount variant against your board design requirements. Confirm that the photovoltaic output type aligns with your load drive specifications, as it differs from transistor or logic gate outputs. Ensure the 5300Vrms isolation rating meets your safety compliance standards.

Selection Notes

Select this component when space constraints require multiple isolated channels in a small footprint. The photovoltaic output is suitable for low-power sensing or driving high-impedance inputs without requiring an external supply on the output side. Consider the thermal characteristics of the SMD package during layout.

Part Context

This device belongs to the TIL196 series, which represents a family of multi-channel optoisolators. The SM designation specifically identifies the surface-mount version of the standard through-hole TIL196, allowing for automated assembly processes while maintaining the same electrical performance characteristics.
