Overview
The HI-8192PCTF is a quad single-pole single-throw (SPST) analog switch manufactured by Holt Integrated Circuits. It utilizes Silicon-on-Insulator (SOI) technology to provide robust performance in high-temperature environments, supporting operating temperatures up to 175°C in plastic packages. The device features an on-chip charge pump that generates the necessary gate drive voltages from a single 3.3V or 5V supply, enabling a switching range of +/-12V. Key electrical characteristics include a typical on-resistance (RON) of 8 ohms at VDD between 3.0V and 5.5V, with RON deviation less than 5% over a -5V to +5V signal range. The component offers low off-state leakage, typically under 10nA, and low charge injection below 10pC.
Feature Summary
- High-temperature operation capability suitable for demanding avionics applications
- On-chip charge pump eliminates need for external negative voltage supplies
- Low off-state leakage and minimal charge injection for precision signal handling
- Bidirectional signal conduction with consistent on-resistance across signal polarity
Applications
- High-temperature avionics systems
- Oil exploration and down-hole drilling instrumentation
- Data bus isolation circuits
- Precision data acquisition systems
Procurement Notes
Verify the specific suffix 'PCTF' against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with system voltage requirements, as the device operates on a single 3.3V or 5V supply while handling higher signal swings via internal charge pumping. Confirm RoHS compliance status if required by your assembly specifications.
Selection Notes
Select this component when designing for extended temperature ranges exceeding standard industrial limits, specifically up to 175°C. It is appropriate for applications requiring bidirectional analog switching with low distortion and high isolation. Consider the pin count and package constraints, as the SOI technology allows for compact designs without sacrificing thermal performance or switching speed compared to traditional CMOS switches.
Part Context
Holt Integrated Circuits specializes in mixed-signal solutions for military, aerospace, and industrial markets. The HI-8192 belongs to their family of high-reliability analog switches built on SOI technology. This technology provides inherent radiation hardness and latch-up immunity, making the series distinct from standard commercial analog switches found in general consumer electronics.
Replacement Considerations
Publicly confirmed substitute part numbers for HI-8192PCTF are not available in the provided documentation. Verify functional equivalence regarding SOI technology, temperature rating, and on-chip charge pump presence before considering alternative manufacturers.
