ISL43144IVZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43144IVZ-T is a CMOS analog switch manufactured by Renesas Electronics, housed in a 16-pin TSSOP package. It integrates four independent single-pole single-throw (SPST) switches within a single integrated circuit. The device operates with a single supply voltage ranging from 3.3V to 5V or dual supplies of ±2.6V to ±6V. Key electrical specifications include a maximum on-resistance of 25Ω and a channel-to-channel matching of 2Ω. Switching times are specified at a maximum of 80ns for turn-on and 30ns for turn-off. The component supports an operating temperature range from -40°C to 85°C.

• Audio and video signal switching
• Instrumentation front-end multiplexing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix IVZ-T against the manufacturer's current datasheet to confirm pinout and electrical tolerances. Check for product discontinuance notices as Intersil/Renesas frequently updates lifecycle status. Ensure the TSSOP-16 footprint matches the PCB design requirements before ordering.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four isolated SPST switches are required in a small form factor. Compare the 25Ω on-resistance against application signal levels to ensure acceptable voltage drop. Verify that the 3.3V to 5V single-supply operation aligns with the system power architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43144 series of high-speed analog switches. It is functionally related to the ISL43141 but differs in on-resistance specifications and supply voltage ranges. The series is designed for applications requiring multiple switched channels with low distortion.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct cross-reference models from Renesas such as the ISL43144IRZ-T. Verify equivalent packages like SOIC-16 if TSSOP availability is limited. Confirm that replacement parts maintain the same 25Ω Ron and 16-pin configuration.
