HI1-5044/883

Analog Switches, Multiplexers, Demultiplexers Overview

The HI1-5044/883 is a dual SPDT CMOS analog switch processed in accordance with MIL-STD-883. It features low on-resistance of 25 ohms typical and 50 ohms maximum, supporting signal currents up to 70mA. The device operates over a wide analog signal range of ±15V and provides break-before-make switching with turn-on times of 370ns typical and 800ns maximum. Turn-off time is 280ns typical and 400ns maximum. It utilizes dielectric isolation for latch-free operation and low leakage currents of 0.8nA at +25°C. Power consumption is 1.5mW at +25°C. The component is available in a 20-lead CLCC package and functions within a temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix and lot traceability against current MIL-STD-883 requirements before procurement. Confirm that the supplier provides full certification of conformance to paragraph 1.2.1. Ensure the component meets the Class Q qualification level if required by the system specification. Check for availability of original manufacturer documentation or authorized distributor certificates to validate authenticity and performance history.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dielectric isolation and latch-up immunity are critical for high-reliability applications. The wide supply voltage range of ±15V accommodates various analog signal levels. Verify that the 20-lead CLCC package fits the thermal and mechanical constraints of the design. Consider the 70mA current capability for driving moderate loads without external buffering.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the Harris Corporation (now part of Elmos Semiconductor) family of CMOS analog switches designed for aerospace and defense markets. The /883 suffix indicates processing under MIL-STD-883 standards. It is functionally similar to other dual SPDT analog switches but distinguished by its dielectric isolation and harsh environment qualification.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Evaluate equivalents based on pin compatibility, electrical parameters, and MIL-STD-883 compliance. Verify that any replacement maintains the same dielectric isolation and latch-up protection characteristics.
