ISL43145IVZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43145IVZ is a CMOS precision quad SPST analog switch by Renesas, operating on single +2V to +12V or dual ±2V to ±6V supplies. It features two normally open and two normally closed channels with a maximum on-resistance of 25 ohms and flatness of 5 ohms. Channel-to-channel mismatch is less than 2 ohms. Key electrical parameters include 80ns turn-on time, 30ns turn-off time, 1pC charge injection, and -90dB crosstalk at 100kHz. Leakage current is 1nA max, with 7pF channel capacitance. It operates from -40°C to 85°C in a 16-TSSOP package.

• Flexible power supply configuration supporting both single-ended and dual-rail operation for diverse system requirements.
• Integrated normally open and normally closed switching configurations within a single quad package for versatile signal routing.

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in data acquisition systems
• Audio and video signal switching applications
• Programmable gain amplifier circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix IVZ against the official datasheet to confirm the 16-TSSOP package and tape-and-reel quantity. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Check component availability status, as this part may be subject to end-of-life notices or production changes. Ensure the ordering code matches the exact pinout and electrical specifications required for the design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ISL43145IVZ when a combination of normally open and normally closed switches is required in a single package. The 25-ohm on-resistance suits applications demanding lower voltage drop compared to higher resistance alternatives. Consider the 5-ohm flatness for maintaining signal integrity across varying input levels. Evaluate the dual-supply capability if negative rail generation is available in the target system.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ISL4314x family of low-voltage analog switches. The series includes variants with different switch configurations: ISL43143 offers four normally closed switches, while ISL43144 provides four normally open switches. The ISL43145 uniquely combines two NO and two NC channels. All devices share similar electrical characteristics and package options, designed for precision analog signal handling.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include ISL43143IVZ (four NC) and ISL43144IVZ (four NO). Verify pin compatibility and electrical parameters before substitution. Cross-model generic features do not guarantee functional equivalence due to differing switch states.
