Overview
The HI-8202PSIF is a quad analog switch from the HI-8200H family, fabricated using Silicon-on-Insulator (SOI) technology to ensure latch-up-free operation and high isolation. It features an on-chip high-voltage gate drive that enables a +/-12V switching range from a single 3.3V or 5V supply. The device combines two normally open and two normally closed SPST switches. Key electrical parameters include a typical on-resistance of 8 ohms at 25°C with less than 5% deviation in a +/-5V range, maximum off-state leakage under 10nA, and charge injection below 10pC. Switching times are typically 180ns for turn-on and 60ns for turn-off.
Feature Summary
- On-chip high-voltage gate drive allows +/-12V signal switching from low-voltage digital supplies
- Silicon-on-Insulator construction provides latch-up immunity and minimal off-state leakage
- Integrated charge pump supports simultaneous 5KHz on/off cycling for all channels
Applications
- High temperature avionics systems
- Oil exploration and down-hole drilling equipment
- Data bus isolation interfaces
- Precision data acquisition systems
Procurement Notes
Verify the specific suffix 'PSIF' against the manufacturer's official datasheet to confirm package type and material specifications. Ensure the component meets the required environmental standards for the intended operating temperature range. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before procurement.
Selection Notes
Select this component when high-temperature stability and low leakage are critical requirements. The HI-8202 variant specifically provides a mixed configuration of normally open and normally closed switches within a single package. Verify that the application voltage does not exceed the +/-12V limit enabled by the internal charge pump circuitry.
Part Context
This component belongs to the HI-8200H series of analog switches designed for harsh environments. The series includes HI-8200H (four NO), HI-8201H (four NC), and HI-8202H (two NO/NC). These devices are optimized for military, aerospace, and industrial markets where reliability under extreme thermal conditions is mandatory.
Replacement Considerations
Direct replacements must match the SOI technology and +/-12V switching capability. Verify pin compatibility for the 16-pin CSP package. Alternative parts should offer similar on-resistance flatness and low charge injection characteristics for precision applications.
