ISL43144IVZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43144IVZ is a quad single-pole single-throw (SPST) normally open analog switch manufactured by Renesas Electronics Corporation. It integrates four independent channels within a 16-pin TSSOP surface-mount package. The device operates on a single supply voltage ranging from 2.7V to 12V or dual supplies of ±2.6V to ±6V. Key electrical specifications include a maximum on-resistance of 25 ohms, an on-resistance matching of 2 ohms, and a channel-to-channel crosstalk of -90dB at 100kHz. Switching times are specified with a maximum turn-on time of 80ns and turn-off time of 30ns. The component supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix IVZ against the manufacturer's current datasheet to confirm pinout and package dimensions. Confirm RoHS compliance status as regulatory requirements may evolve. Check for End-of-Life notifications or obsolescence notices from Renesas, as availability for this component type may be restricted. Ensure the ordering quantity aligns with distributor minimums if applicable.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ISL43144IVZ when four independent analog switches are required in a small footprint. Compare the 25-ohm on-resistance against application signal levels to ensure acceptable voltage drop. Verify that the 2.7V to 12V single supply range matches the system power rails. Consider the 16-TSSOP package constraints for PCB layout and thermal management during selection.
