HI3256JCQ

Analog To Digital Converters (ADC) Overview

The HI3256JCQ is a high-speed analog multiplexer manufactured by Harris Corporation. It features a single channel with eight selectable inputs, designed for applications requiring precise signal routing. The device utilizes CMOS technology and operates within a wide temperature range of -55°C to 125°C. It is housed in a ceramic QCCN-32 package, providing robust performance for industrial and military environments. Key electrical characteristics include low on-resistance and fast switching times, ensuring minimal signal distortion during operation.

Analog To Digital Converters (ADC) Feature Summary

• Single 8-channel analog multiplexer configuration
• CMOS technology for low power consumption
• Extended temperature range: -55°C to 125°C
• Ceramic QCCN-32 package for durability

Analog To Digital Converters (ADC) Applications

• Data acquisition systems
• Industrial process control
• Test and measurement equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'JCQ' against official Harris datasheets to confirm pinout and electrical specifications. Ensure compatibility with existing board layouts due to the QCCN-32 package dimensions. Check for RoHS compliance status as older Harris components may not meet current environmental standards.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel multiplexing solution is required in harsh thermal environments. Compare on-resistance and leakage current specifications against alternative CMOS multiplexers if lower power or higher speed is needed. Confirm that the ceramic package is suitable for the intended assembly process.

Analog To Digital Converters (ADC) Part Context

Harris Semiconductor was acquired by Intersil, which later merged with Renesas Electronics. The HI3256 series represents legacy analog switching products from Harris's portfolio. These components are often used in replacement scenarios for older industrial equipment where original designs specified Harris parts.

Analog To Digital Converters (ADC) Replacement Considerations

Check Intersil or Renesas catalogs for direct cross-references such as ISL3256 or similar series. Verify pin-to-pin compatibility before substitution. Consider modern equivalents from other manufacturers if lead times for legacy Harris parts are prohibitive.
