ISL43144IRZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43144IRZ-T is a quad single-pole single-throw (SPST) normally open analog switch manufactured by Renesas Electronics. It operates within a supply voltage range of 2.7V to 12V for single supplies or ±2.6V to ±6V for dual supplies. The device features a maximum on-resistance of 65 ohms and a channel-to-channel matching of 2 ohms. Switching times are specified at a maximum of 80ns for turn-on and 30ns for turn-off. It utilizes a 16-pin QFN package with dimensions of 3x3 mm.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates four independent SPST switches in a compact surface-mount package

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the obsolete status and discontinuance notification from Renesas before procurement planning. Confirm availability through authorized distributors as stock may be limited. Ensure the specific tape-and-reel packaging matches the required quantity for production lines.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with moderate speed switching characteristics. Compare the 65-ohm on-resistance against load requirements. Verify that the 16-QFN package fits the PCB footprint constraints and thermal management needs of the design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43144 series of CMOS analog switches. It shares functional similarities with other quad SPST devices but is distinguished by its specific resistance and switching time parameters. The IRZ suffix indicates the RoHS-compliant lead-free QFN package variant.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG1212YCPZ-500RL7 is listed as a similar replacement option. Evaluate pin compatibility and electrical parameter alignment, particularly on-resistance and switching speeds, before substituting.
