Overview
The HI4-0201/B is a high-speed, quad single-pole single-throw (SPST) CMOS analog switch manufactured by Rochester Electronics. It features four independent channels within a single package, designed for signal routing and switching applications. The device operates with a wide supply voltage range, supporting dual supplies from -4.5V to -18V and +4.5V to +18V. It utilizes a 20-pin ceramic leaded ceramic chip carrier (LCC) package. Key electrical characteristics include a low on-resistance and high off-isolation, ensuring minimal signal distortion and leakage in analog circuits.
Feature Summary
- Quad SPST configuration for multi-channel signal routing
- High-speed CMOS technology for fast switching transitions
- Wide dual-supply voltage operation capability
- Ceramic LCC package for robust thermal and mechanical performance
Applications
- Data acquisition systems requiring precise signal selection
- Communication equipment for channel switching
- Instrumentation front-end signal conditioning
- Test and measurement equipment multiplexing
Procurement Notes
Verify the specific suffix 'B' against the manufacturer's current datasheet to confirm pinout compatibility and material composition. Check for RoHS compliance status as older ceramic packages may differ from modern standards. Confirm availability through authorized distributors specializing in legacy or discontinued components, as stock levels vary significantly for this part number.
Selection Notes
Select this component when high isolation and low capacitance are required for multiple independent analog signals. Ensure the system power supply matches the specified dual-voltage range. Consider the ceramic package size and mounting requirements during PCB layout. Compare on-resistance values with other switches if signal integrity at high frequencies is critical.
Part Context
This component belongs to the HI4-0201 family of analog switches. It is a quad version of the single-channel HI4-0201. The '/B' suffix typically denotes a specific package variant or processing standard within the Maxim/Rochester product line. It serves as a replacement for legacy designs originally using Harris or Maxim branded parts.
Replacement Considerations
Direct replacements include the HI4-0201HS-8 and HI4-0201-8. Verify pin-to-pin compatibility before substitution. Check if the alternative package type meets the physical constraints of the existing design. Ensure electrical parameters such as on-resistance and bandwidth remain within acceptable limits for the application.
