ISL43143IV-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43143IV-T is a quad single-pole single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It features four independent channels in a 16-pin TSSOP package, designed for signal routing applications requiring low on-resistance and high bandwidth. The device operates with a single supply voltage ranging from 2.7V to 12V or dual supplies of ±2.6V to ±6V. Key electrical characteristics include a maximum on-resistance of 25 ohms, a channel-to-channel matching of 500 milliohms, and an off-state leakage current of 100pA. Switching times are specified at 65ns for turn-on and 50ns for turn-off, supporting efficient data acquisition and multiplexing systems.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' against official Renesas documentation to confirm tape-and-reel packaging status. Ensure compliance with RoHS directives as standard versions may vary. Cross-reference the exact part number with authorized distributors to confirm availability and lead times. Validate that the TSSOP-16 package matches the design requirements for thermal and mechanical constraints.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST switch with 25-ohm on-resistance is required for signals up to 12V single supply. Consider the 16-pin TSSOP footprint for PCB layout compatibility. Evaluate the 100pA leakage current specification against system noise floors. Confirm operating temperature range suitability for the intended environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43143 series belongs to Renesas' portfolio of high-performance analog switches. This family offers low on-resistance and fast switching speeds suitable for precision applications. The IV-T designation indicates the specific pin-compatible variant with tape-and-reel packaging, distinguishing it from bulk or other package options within the same functional family.
