ADG5404FBCPZ-RL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG5404F is a fault-protected, latch-up immune analog multiplexer featuring four single channels. It provides overvoltage protection up to ±55 V on source pins and includes interrupt flags for fault detection. The device operates with dual supplies from ±5 V to ±22 V or a single supply from 8 V to 44 V. Typical on-resistance is 10 Ω with a maximum flatness of 0.5 Ω. Dynamic characteristics include a transition time of 570 ns max and an off-isolation of -72 dB at 1 MHz. The part supports break-before-make switching and maintains a known state without digital inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package type required for the design, as the ADG5404F family is available in both 14-lead TSSOP and 16-lead LFCSP configurations. Confirm that the ordering suffix matches the desired reel or tube packaging format. Ensure the voltage ratings align with the system's maximum expected signal levels to utilize the full fault protection capabilities effectively.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-voltage fault protection and real-time status monitoring are critical requirements. The integrated interrupt flags allow the host processor to detect overvoltage events immediately. Consider the thermal impedance of the chosen package if continuous current handling near the absolute maximum ratings is anticipated in the application environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the ADG5404F series of fault-protected analog switches. It differs from standard multiplexers by including dedicated fault flag outputs and robust overvoltage blocking capabilities. The architecture utilizes trench isolation to prevent latch-up, making it suitable for harsh industrial environments where signal integrity and system safety are paramount.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the Analog Devices portfolio include the ADG5404, which lacks the advanced fault detection features. Verify pin compatibility and electrical specifications carefully when replacing legacy components with similar but non-fault-protected multiplexers.
