HI-8192PSTF

Overview

The HI-8192PSTF is a quad single-pole single-throw (SPST) analog switch manufactured by Holt Integrated Circuits using insulated-on-silicon (SOI) technology. It operates on a single 3.3V or 5V supply to generate internal +/-12V switching ranges, enabling low leakage and latch-up immunity. The device features a typical on-resistance of 8 ohms with less than 5% deviation across the signal range. Switching times are typically 180ns for turn-on and 60ns for turn-off. It supports up to 5kHz open/close cycle rates and maintains off-state leakage below 10nA with charge injection under 10pC.

Feature Summary

• Insulated-on-silicon construction ensures robust operation without latch-up risks
• Integrated high-voltage gate driver allows control from standard logic levels
• Low off-state leakage suitable for precision sampling applications
• Bidirectional signal conduction capability

Applications

• High temperature avionics systems
• Data bus isolation circuits
• Precision data acquisition systems

Procurement Notes

Verify the specific suffix 'TF' against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements and thermal management needs for aerospace environments.

Selection Notes

Select this component when high reliability and low leakage are critical in harsh environments. Verify that the SOI technology meets specific radiation hardness or thermal stability requirements compared to standard CMOS alternatives.

Part Context

This part belongs to the HI-8200/8201/8202 family of analog switches designed for demanding industrial and military applications. It shares core architectural features with other variants in the series while offering specific pinout and configuration options.

Replacement Considerations

Check for direct equivalents within the HI-8200 series such as HI-8200PSIF or HI-8202PSMF if functional differences align with design constraints.
