ADG5421BCPZ-RL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG5421BCPZ-RL7 is a high voltage, latch-up proof analog switch containing two independent single-pole/single-throw (SPST) channels. It operates from dual supplies of ±9 V to ±22 V or a single supply of 9 V to 40 V, with maximum ratings up to 48 V. The device features a low on-resistance of 13.5 Ω typical and supports an analog signal range extending from VSS to VDD. It includes 3 V logic compatible digital inputs without requiring a separate VL supply. Packaged in a 10-lead LFCSP (3 mm × 3 mm), it offers an operating temperature range of -40°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Trench isolation technology eliminates parasitic junctions to ensure complete immunity against latch-up under all circumstances.
• High electrostatic discharge robustness with an 8 kV Human Body Model rating reduces the need for external protection circuitry.
• Bi-directional conduction allows signals to extend fully to the power supply rails in both on and off states.

Analog Switches, Multiplexers, Demultiplexers Applications

• High voltage signal routing
• Automatic test equipment
• Precision data acquisition systems
• Industrial instrumentation

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging configuration required for your assembly line. Confirm that the CP-10-9 package option matches your PCB footprint design. Ensure the component meets RoHS compliance standards as indicated by the Z suffix in the manufacturer's ordering guide.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this model when dual SPST switching is required within a compact surface-mount footprint. The LFCSP package provides thermal advantages over MSOP variants. Verify that the 13.5 Ω on-resistance meets the distortion requirements of your specific application bandwidth and load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG54xx family of high voltage CMOS analog switches. It shares architectural similarities with the ADG5423, which offers break-before-make timing for multiplexer applications. Both devices utilize the same trench isolation process to achieve latch-up immunity in harsh industrial environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG5421BRMZ serves as a pin-compatible alternative in a 10-lead MSOP package. The ADG5423BCPZ-RL7 is functionally similar but provides break-before-make timing suitable for multiplexing. Verify thermal performance differences between LFCSP and MSOP packages during substitution.
