ISL43L122IR-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L122IR-T is a dual single-pole/single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation, featuring one normally open and one normally closed channel. It operates on a single supply voltage ranging from +1.65V to +3.6V. The device provides an ultra-low ON-resistance of 0.16Ω at 3V and 0.26Ω at 1.8V, with a maximum switching speed of 30ns for turn-on and 25ns for turn-off. Packaged in an 8-lead Thin Dual Flat No-Lead (TDFN) format measuring 3x3mm, it supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Ultra-low ON-resistance ensures minimal signal insertion loss and distortion for precision applications.
• Fast switching speeds enable high-frequency performance suitable for demanding data transmission environments.
• Single-supply operation simplifies power management in battery-powered portable devices.

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery powered handheld and portable equipment
• Cellular and mobile phones
• Portable test and measurement instruments

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IR' confirms the 8-lead TDFN package and 'T' indicates tape and reel packaging. Confirm RoHS compliance status as the base datasheet lists both compliant and non-compliant variants. Ensure the source document matches the manufacturer's current revision to validate electrical limits and thermal characteristics.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mixed NO/NC configuration is required within a dual SPST architecture. Compare against ISL43L120 for dual NO or ISL43L121 for dual NC needs. Evaluate the 3x3mm TDFN footprint against MSOP options if board space constraints dictate the package choice.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43L12X family of low-voltage analog switches. It shares core electrical specifications with the ISL43L120 and ISL43L121 but differs in internal logic to provide one normally open and one normally closed switch. This configuration allows for flexible signal routing without external components.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

ISL43L122IU serves as the pin-compatible alternative in the MSOP package. Verify that the replacement maintains the same 3x3mm TDFN form factor if board layout changes are not permitted.
