ISL43112IBZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43112IBZ is a low-voltage, dual supply, single-pole/single-throw (SPST) high-performance analog switch manufactured by Renesas Electronics Corporation. It operates from ±1.5V to ±6V supplies and is fully specified for 10% tolerance ±5V and ±3.3V configurations. The device features an ON-resistance of 15Ω with an rON flatness of 5Ω. Charge injection is limited to 7pC, while leakage current remains at a maximum of 5nA in the off state and 20nA in the on state at 85°C. Switching times are characterized by tON of 40ns and tOFF of 25ns. It provides minimum 2000V ESD protection per Method 3015.7 and is CMOS logic compatible.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix IBZ against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with ±1.5V to ±6V supply rails during design validation. Confirm RoHS compliance status as stated in the datasheet prior to procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing low-voltage analog signal paths requiring SPST functionality. The ISL43112 variant is Normally Open (NO), distinguishing it from the ISL43113 Normally Closed (NC) version. Consider the SOT-23 packaging constraints and the specific rON flatness requirements for maintaining signal integrity across the input range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the Intersil ISL4311x family of precision analog switches, now integrated into the Renesas portfolio following the acquisition of Intersil. These devices are designed for applications demanding sub-nanoamp leakage currents and fast switching speeds within a compact micro-package format.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ISL43113 serves as the complementary Normally Closed (NC) variant within the same family. Verify pinout compatibility if substituting between NO and NC types in existing designs.
