ISL43144IV-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43144IV-T is a high-performance analog switch manufactured by Renesas Electronics Corporation. It integrates four independent single-pole single-throw (SPST) normally-open switches within a single package. The device utilizes CMOS logic technology and operates with a supply voltage range of 2.7V to 12V for single-supply applications, or ±2.6V to ±6V for dual-supply configurations. Key electrical specifications include a maximum on-resistance of 25Ω and a channel-to-channel matching of 500mΩ. The component supports an operating temperature range from -40°C to +85°C and is housed in a 16-pin TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' against the manufacturer's official documentation to confirm tape-and-reel packaging requirements. Ensure the ordering part number matches the exact voltage and temperature grade specified in the current datasheet. Cross-reference the RoHS compliance status as manufacturing processes may evolve. Confirm availability through authorized distributors given potential lifecycle changes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when multiple isolated signal paths are required in a compact form factor. The 25Ω on-resistance makes it suitable for precision analog signals where voltage drop must be minimized. Verify that the input signal amplitude remains within the absolute maximum ratings relative to the chosen supply voltage to prevent latch-up or damage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43144 series of analog switches. It shares functional similarities with other members of the family but differs in package type and shipping configuration. The 'IV' designation typically indicates the TSSOP-16 package variant, while the '-T' suffix denotes reel packaging. It serves as a direct replacement for legacy Intersil parts with equivalent pinouts and electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the ISL43144IVZ for lead-free compliant versions in the same package. For reel-packaged equivalents, verify the ISL43144IRZ-T if QFN packaging is acceptable. Always check for updated RoHS directives and ensure pin compatibility before substituting.
