Overview
The HI-8197PSTF is a quad single-pole single-throw (SPST) analog switch manufactured by Holt Integrated Circuits Inc. It features four independent switches within a single 16-SOIC package, offering an on-resistance of 31 Ohms. The device operates across an extended industrial temperature range from -55°C to +125°C and is RoHS compliant with a Moisture Sensitivity Level of 1.
Feature Summary
- Integrates four independent SPST analog switches in a compact surface-mount package
- Provides low on-resistance for efficient signal routing
- Supports extended industrial temperature operation for harsh environments
Applications
- Avionics data bus signal switching
- Flight control system interconnects
- Navigation equipment signal routing
Procurement Notes
Verify the specific suffix 'PSTF' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure the procurement channel provides traceability documentation required for avionics or safety-critical applications. Confirm that the component meets the specified RoHS compliance standards for the intended market.
Selection Notes
Select this component when multiple independent SPST switching functions are required in a space-constrained design. The wide operating temperature range makes it suitable for industrial and aerospace applications where standard commercial grade parts may fail. Consider the 31 Ohm on-resistance impact on signal integrity for high-frequency applications.
Part Context
Holt Integrated Circuits specializes in avionics data bus solutions, supplying components to over 400 manufacturers globally. The HI-8197 series fits within their portfolio of interface ICs designed for flight control, navigation, and communication systems, ensuring reliability in critical aerospace environments.
Replacement Considerations
Check for direct substitutes such as the HI-8200PCIF or HI-8201PCIF if different packaging or minor parameter variations are acceptable. Verify pin-to-pin compatibility before replacing to avoid redesigning the PCB layout.
