TIL193AX

Overview

The TIL193AX is a quad optocoupler manufactured by Isocom Components 2004 LTD, featuring four independent channels within a single package. It utilizes a photovoltaic output configuration and is housed in a 16-pin DIP (Dual In-line Package) suitable for through-hole mounting. The device provides an isolation voltage of 5300Vrms between input and output circuits. Key electrical parameters include a maximum forward voltage of 1.4V and a maximum input current of 50mA. The typical rise time is specified at 100μs, with a typical fall time also at 100μs. This component is designed for applications requiring high-density signal isolation.

Feature Summary

• Quad channel architecture providing four isolated signal paths in a single package
• Photovoltaic output configuration for galvanic isolation
• High isolation voltage rating of 5300Vrms ensuring robust circuit separation
• Through-hole compatible 16-pin DIP packaging for standard PCB integration

Applications

• Multi-channel data acquisition systems requiring signal isolation
• Industrial control interfaces with multiple isolated inputs or outputs
• Communication gateways needing quad-channel galvanic separation
• Test and measurement equipment requiring high-voltage isolation barriers

Procurement Notes

Verify the specific pinout configuration against the official datasheet to ensure compatibility with existing PCB footprints, as quad-channel DIP packages may vary in pin assignment across manufacturers. Confirm that the 16-pin form factor matches the target assembly requirements. Ensure that the photovoltaic output characteristics align with the load requirements of the receiving circuitry, particularly regarding open-circuit voltage capabilities. Cross-reference the isolation voltage rating with system safety standards applicable to the end product.

Selection Notes

Select this component when multiple isolated channels are required within a compact footprint, reducing board space compared to individual dual-channel units. The photovoltaic output type is suitable for applications where zero quiescent current is beneficial or where the output acts as a voltage source rather than a current sink. Consider the 100μs switching speed limitations; this device is appropriate for low-frequency signal isolation rather than high-speed digital communication. Verify thermal management needs, as four channels operating simultaneously may generate heat within the DIP package.

Part Context

The brand maintains production facilities and testing operations to support global supply chains for these electronic components.

Replacement Considerations

Publicly confirmed substitute part numbers for the TIL193AX were not identified in the provided documentation. When seeking alternatives, prioritize quad-channel optocouplers in 16-pin DIP packages with photovoltaic outputs and comparable isolation voltages. Verify that any replacement maintains the same pinout configuration to avoid redesigning the PCB layout. Consult manufacturer cross-reference guides for equivalent parts from other suppliers offering similar quad-channel isolation solutions.
