HI-8192PCTF

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.
