Overview
The HI-8197PCIF is a quad single-pole single-throw (SPST) analog switch manufactured by Holt Integrated Circuits Inc. It features four independent channels within a 16-pin Chip Scale Package (CSP). The device supports both normally open and normally closed configurations with a maximum on-resistance of 31 ohms. It operates on a single power supply ranging from 3V to 5.5V and functions reliably across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent SPST analog switching channels in a compact footprint
- Supports dual configuration options for normally open and normally closed circuit states
- Maintains low charge injection characteristics for signal integrity preservation
- Designed for robust operation under demanding industrial environmental conditions
Applications
- Avionics data bus signal routing and management systems
- Flight control and navigation equipment interface circuits
- Engine management system sensor signal switching
- Communications safety equipment signal path selection
Procurement Notes
Verify the specific package marking and date code against the manufacturer's latest production records to ensure authenticity. Confirm that the received components match the exact 16-CSP physical dimensions and pinout specifications required for your PCB layout. Request detailed test reports or lot traceability documentation if the application demands strict quality assurance protocols for critical systems.
Selection Notes
Select this component when a compact solution is required for switching multiple analog signals independently. The choice between normally open and normally closed functionality should align with the default state requirements of the target circuit design. Ensure the operating voltage range and thermal environment of the application fall within the specified electrical and temperature limits for reliable performance.
Part Context
Holt Integrated Circuits specializes in providing integrated solutions for the avionics industry, supporting standards such as ARINC 429 and MIL-STD-1553. The HI-8197PCIF belongs to a family of protocol ICs and switches widely used in commercial aircraft and military helicopter programs. These components are engineered to meet the rigorous reliability and performance standards demanded by aerospace and defense applications.
Replacement Considerations
Consult official manufacturer substitution lists for verified equivalents. Cross-reference pin compatibility and electrical parameters before considering alternative sources.
