Procurement Notes
Verify the manufacturer designation as Holt Integrated Circuits Inc. when sourcing components. Confirm the specific suffix PSTF corresponds to the 16-SOIC package variant. Ensure compliance with RoHS standards and lead-free requirements for procurement specifications. Cross-reference the part number against official distributor catalogs to confirm availability status.
Selection Notes
Select this component for applications requiring multiple isolated analog signal paths controlled by standard logic levels. The 17 Ohm on-resistance suits general-purpose signal routing where low distortion is required. Consider the 16-SOIC footprint for PCB layout constraints. Evaluate thermal dissipation capabilities based on the expected current load across the four channels.
Part Context
Holt Integrated Circuits Inc. specializes in avionics data bus solutions, supplying components to over 400 manufacturers globally. The HI-8191PSTF belongs to their portfolio of analog switches designed for critical aerospace and defense environments. This series supports various flight control, navigation, and safety equipment applications requiring reliable signal switching.
Replacement Considerations
Consult official datasheets for direct pin-compatible substitutes from the same product family. Verify that alternative parts maintain identical 3.3V/5.0V logic compatibility and SPST configuration. Ensure package dimensions match the 16-SOIC form factor for seamless board replacement.
