HI1-0201HS/883B

Overview

The HI1-0201HS/883B is a high-speed analog multiplexer switch manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for military and aerospace applications as indicated by the /883B suffix denoting MIL-PRF-38534 compliance. This single-channel SPDT switch utilizes CMOS technology to provide low on-resistance and fast switching speeds. It operates within an extended temperature range of -55°C to +125°C and supports dual power supplies up to ±20V or a single supply up to 30V. The device is housed in a hermetic CDIP-16 package, ensuring reliability in harsh environments while maintaining signal integrity through low charge injection and high off-isolation characteristics typical of precision analog switches.

Feature Summary

• Hermetically sealed ceramic dual in-line package (CDIP) suitable for radiation-hardened and high-reliability environments
• Single-pole double-throw (SPDT) configuration enabling precise signal routing and selection
• CMOS construction providing low power consumption and compatibility with standard logic levels
• Extended industrial and military temperature rating for operation in extreme thermal conditions

Applications

• Military communication systems requiring reliable signal switching
• Aerospace data acquisition systems needing high-speed analog multiplexing
• Test and measurement equipment operating in harsh environmental conditions
• Medical imaging systems utilizing precision analog signal paths

Procurement Notes

Verify that the component carries the official /883B suffix to confirm compliance with MIL-PRF-38534 specifications. Ensure the supplier provides traceability documentation including lot codes and material certifications. Check for physical damage to the ceramic package pins before integration. Confirm that the source is an authorized distributor or direct manufacturer representative to avoid counterfeit parts. Validate that the part number matches the exact HI1-0201HS variant rather than generic equivalents.

Selection Notes

Select this component when hermetic sealing and radiation hardness are mandatory requirements for the application. Consider the CDIP-16 package constraints if board space is limited compared to surface-mount alternatives. Evaluate the switching speed and on-resistance against system bandwidth requirements. Verify that the control voltage levels are compatible with the available logic interface. Assess the thermal management needs given the operational temperature range and power dissipation characteristics.

Part Context

The HI1-0201 series represents a family of high-speed analog switches from Maxim Integrated, optimized for demanding applications. The /883B designation specifically identifies the version manufactured to meet stringent military quality standards. This part sits within the broader portfolio of precision analog switches used in critical infrastructure. Understanding its position helps in identifying compatible drivers and supporting components for system design.

Replacement Considerations

Direct replacements must also be hermetically sealed and pin-compatible. Verify that any substitute maintains the same SPDT topology and voltage ratings. Cross-reference with other /883B qualified parts from Analog Devices or Raytheon. Ensure that functional equivalence includes switching speed and on-resistance parameters.
