• Programmable gain amplifiers and variable attenuators

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific manufacturer source document for the HI1-5049-5 part number before procurement. Confirm that the component meets all required environmental and electrical specifications for the intended application. Check for any obsolete status or end-of-life notifications associated with this specific Intersil product code.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the HI1-5049-5 when a low on-resistance of 25 ohms is required for analog signal paths. Ensure the system voltage does not exceed the ±15V absolute maximum rating. Consider the package type and pinout compatibility if replacing existing designs. Verify thermal requirements given the 80mA current capability.

Analog Switches, Multiplexers, Demultiplexers Part Context

The HI1-5049-5 belongs to the HI-504X and HI-505X series of CMOS analog switches. This family offers functionally compatible alternatives to older IH-5040 series devices and DG180/DG190 families. The HI1 suffix typically denotes military or extended temperature variants compared to commercial HI-5049 parts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The HI-5049 and HI-5051 series can directly replace IH-5040 series devices. They are also functionally compatible with the DG180 and DG190 family. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
