ISL43240IAZ-T7A

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43240IAZ-T7A is a quad single-pole double-throw (SPDT) analog switch manufactured by Renesas Electronics Corporation. It operates on a single supply voltage ranging from 2 V to 12 V or dual supplies of ±2 V to ±6 V. The device features four independent channels with a maximum on-resistance of 25 Ohms and supports a continuous DC current of 30 mA per channel. Switching performance includes a maximum turn-on time of 65 ns and a turn-off time of 50 ns. It functions within an industrial temperature range of -40°C to +85°C and is housed in a 20-pin SSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix T7A corresponds to the reel packaging format required for your assembly line. Confirm that the SSOP-20 footprint matches your PCB design guidelines. Ensure the component meets RoHS3 compliance standards if mandated by your regional regulations. Cross-reference the manufacturer part number against official Renesas documentation to avoid counterfeit risks.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a compact solution for routing multiple analog signals is required. The 25 Ohm on-resistance is suitable for general-purpose applications but may require calibration in high-precision measurement circuits. Verify that the 30 mA current limit aligns with the load requirements of the connected devices. Consider the 65 ns switching speed for timing-sensitive digital control interfaces.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43240 family of analog switches, designed for general-purpose signal switching tasks. It serves as a discrete alternative to integrated multiplexer arrays, offering flexibility in system design.
