Overview
The HI-8201PSIF is a quad single-pole single-throw (SPST) normally closed analog switch manufactured by Holt Integrated Circuits Inc. It utilizes Insulator on Silicon (SOI) technology to ensure latch-up immunity and low leakage characteristics. The device operates with a single supply voltage ranging from 3V to 5.5V. Key electrical parameters include a maximum on-resistance of 10 ohms, a charge injection of -20pC, and a maximum off-state leakage current of 1nA. Switching times are specified at a maximum of 250ns for turn-on and 150ns for turn-off. The component is housed in a 16-CSP (5x5) package and supports an operating temperature range of -40°C to 85°C.
Feature Summary
- Built with SOI technology for robust latch-up protection and high isolation
- Features extremely low charge injection and minimal off-state leakage
- Provides optimized performance for high-temperature avionics environments
Applications
- High temperature avionics systems
- Oil exploration and down-hole drilling equipment
- Data bus isolation circuits
- Precision data acquisition systems
Procurement Notes
Verify the specific suffix PSIF against the manufacturer's official datasheet to confirm pinout compatibility and thermal specifications. Ensure that the 16-CSP packaging requirements align with your PCB assembly capabilities. Confirm RoHS3 compliance status if required by your regulatory framework before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring normally closed logic states within a compact surface-mount footprint. The low on-resistance and fast switching speeds make it suitable for signal routing in noisy or high-frequency environments. Consider the -40°C to 85°C operating range to ensure reliability under standard industrial conditions.
Part Context
This part belongs to the HI-8200/8201/8202 family of analog switches from Holt Integrated Circuits. These devices are engineered for demanding applications where reliability and speed are critical. The HI-8201 variant specifically provides four normally closed channels, distinguishing it from the HI-8200 (normally open) and HI-8202 (mixed configuration) models within the same series.
Replacement Considerations
Publicly confirmed substitute part numbers for the HI-8201PSIF were not identified in available documentation. Verify functional equivalence carefully if considering alternative vendors, as pinouts and electrical tolerances may differ significantly across manufacturers.
