HI1-0509A-7

Overview

The HI1-0509A-7 is a monolithic CMOS multiplexer manufactured by Harris Corporation. It integrates an array of four differential analog switches, a digital decoder circuit for channel selection, and a voltage reference for logic thresholds. The device features an enable input for system expansion and utilizes Dielectric Isolation (DI) technology to eliminate latch-up issues while reducing substrate leakage and parasitic capacitance compared to conventional junction-isolated CMOS processes.

Feature Summary

Dielectric Isolation process eliminates latch-up and reduces parasitic capacitance
Integrated digital decoder with internal +5V logic threshold reference
Direct interface capability with standard logic families without pullup resistors
Built-in transient overvoltage protection on digital inputs

Applications

Harsh environment signal routing systems
MIL-STD-883 Class Q qualified applications
Data acquisition systems requiring differential inputs
Multiplexing arrays in aerospace instrumentation

Procurement Notes

Verify the specific suffix 'A-7' against official manufacturer documentation to confirm package type and temperature range variations. Confirm RoHS compliance status as older Harris CMOS parts may not meet current environmental standards. Validate supply chain authenticity through authorized distributors or certified surplus dealers due to potential obsolescence.

Selection Notes

Select this component when differential signal integrity is critical and latch-up immunity is required in harsh environments. The integrated decoder simplifies control logic, while the DI process ensures reliability where standard CMOS might fail. Ensure supply voltages match the ±10V specification and logic levels align with the internal 2.4V/0.8V thresholds.

Part Context

This part belongs to the HI-506/HI-509 family of monolithic CMOS multiplexers. The HI-509 specifically provides four differential channels, distinguishing it from the single-channel HI-506 and other variants in the series. It is designed for high-reliability applications utilizing Harris's proprietary Dielectric Isolation fabrication technique.
