ISL43681IRZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43681IRZ is a precision, bidirectional analog switch configured as an 8-channel multiplexer/demultiplexer. It operates from a single +2V to +12V supply or dual ±2V to ±6V supplies. The device features low on-resistance (39Ω at ±5V), fast switching times (tON/tOFF of 38ns/19ns at 5V), and extremely low off-leakage current (0.1nA at +25°C). It includes inhibit pins to open all signal paths simultaneously and a latch bar pin to lock the last switch address. Digital inputs are TTL/CMOS compatible with thresholds of 0.8V to 2.4V. The component is housed in a 20-lead 4x4mm QFN package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and RoHS compliance status. Confirm that the procurement channel sources genuine Renesas Electronics Corporation components. Ensure proper electrostatic discharge handling procedures are followed during storage and installation due to the sensitivity of the CMOS technology.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexer is required with high-speed switching and low leakage characteristics. Verify that the system power supply falls within the specified single or dual range. Consider the thermal resistance of the QFN package for heat dissipation requirements. Ensure digital control signals meet the specified voltage thresholds for reliable operation.
