HI1-5044-7

Analog Switches, Multiplexers, Demultiplexers Overview

The HI1-5044-7 is a high-speed analog switch manufactured by Harris Corporation. It features a single SPDT (Single Pole Double Throw) configuration housed in a 14-pin CDIP ceramic package. The device operates with a supply voltage range of ±5V to ±15V and supports signal voltages up to the supply rails. Key electrical characteristics include an on-resistance of 25 ohms, an on-capacitance of 12pF, and an off-isolation of 80dB at 1MHz. It exhibits a turn-on/turn-off time of 100ns and a charge injection of 3nC. The component is rated for operation between -55°C and +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer source carefully as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas. Confirm whether the specific unit is a legacy Harris part or a modern equivalent. Check RoHS compliance status as older Harris batches may not meet current environmental standards. Validate the package type matches the required 14-pin CDIP footprint for your PCB design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SPDT switch with high speed and low distortion is required. Compare on-resistance stability and charge injection against alternatives if precision analog signal integrity is critical. Ensure the supply voltage range aligns with your system's power rails. Consider the ceramic package for harsh environment reliability compared to plastic variants.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the HI-5044 series of high-speed analog switches. It is functionally related to other devices in the HI-50xx family designed for precision switching applications. The HI1-5044-7 specifically denotes the military/high-reliability grade version in a ceramic DIP package, distinct from lower-grade plastic versions.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consider the HI-5044-1 or HI-5044-2 for similar functionality in different grades. Intersil and Renesas products may serve as direct replacements after verifying pin compatibility and electrical specifications. Check datasheets for any changes in on-resistance or switching speeds in successor models.
