HI1-0509A-2

Analog Switches, Multiplexers, Demultiplexers Overview

The HI1-0509A-2 is a fault-protected analog multiplexer switch IC manufactured by Intersil. It features a single-ended configuration with eight channels and utilizes a 16-pin DIP package. The device operates within a temperature range of -55 °C to +125 °C and supports a nominal negative supply voltage of -15 V. Key electrical specifications include a maximum on-resistance (Ron) of 1500 Ω and a typical off-isolation of 68 dB. The component is constructed using ceramic glass-sealed packaging and is classified as non-RoHS compliant.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates an array of eight analog switches with a digital decoder circuit for channel selection.
• Incorporates dielectric isolation (DI) CMOS process to eliminate latch-up problems and reduce substrate leakage.
• Includes internal voltage reference for logic thresholds, enabling direct interface with TTL, CMOS, DTL, and PMOS families without pullup resistors.
• Features transient overvoltage protection on digital inputs via series resistors and diode clamps to each supply rail.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring high-reliability signal routing.
• Harsh environment applications meeting MIL-STD-883 qualification standards.
• Test and measurement equipment utilizing fault-protected analog switching.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific manufacturer source, as the HI1-0509A-2 designation appears in documentation associated with both Maxim Integrated and Intersil/Renesas. Confirm RoHS compliance status, as official parameters list the device as non-compliant. Ensure the ceramic DIP16 package matches the target PCB footprint requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when eight-channel single-ended multiplexing is required alongside robust fault protection. The wide operating temperature range (-55 °C to +125 °C) makes it suitable for industrial or military environments. Compare against the HI1-0546 series if input overvoltages are expected, as that family offers enhanced protection characteristics.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the HI-506/HI-507/HI-508/HI-509 monolithic CMOS multiplexer family. These devices share common fabrication technologies, including dielectric isolation and internal logic references. The HI1-0509A-2 specifically denotes the 8-channel single-ended variant within this lineage, often cross-referenced with military-grade equivalents like the JM38510/19008 series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitutes include the DG506A/DG506AA and DG507A/DG507AA from other manufacturers, which are explicitly listed as replaceable counterparts in related datasheet documentation.
