ISL84521IB

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL84521IB is a single-supply, quad SPST analog switch IC manufactured by Renesas Electronics. It operates within a voltage range of 2V to 12V and features four independent channels with low on-resistance of up to 100 Ohms. The device supports dual supply operation between 2V and 6V. Key electrical parameters include a maximum operating time of 80 ns and an idle time of 30 ns. It draws a maximum power current of 1 uA and handles a switch DC current of 10 mA. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IB' against official Renesas documentation to confirm package type and temperature grade. Confirm end-of-life status as distributor listings may vary. Ensure RoHS compliance details match the required manufacturing standards for your assembly line.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring multiple isolated signal paths in a compact footprint. Evaluate the 100 Ohm on-resistance limit against your signal integrity requirements. Consider the 80 ns switching speed for timing-sensitive applications within the specified voltage and temperature constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL84522 series of analog switches. It shares architectural similarities with other members of the family but differs in channel count and configuration. The series is designed for general-purpose signal switching in industrial and commercial environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct pin-compatible alternatives within the ISL8452x family. Verify that any substitute maintains the same 16-pin SOIC-Narrow package dimensions and electrical characteristics.
