HI4-0201/B

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.
