Analog Switches, Multiplexers, Demultiplexers datasheet and documents for MAX4509ESE+

MAX4509ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4509ESE+ is a dual 4-to-1 fault-protected multiplexer housed in a 16-pin Narrow SOIC package. It operates with dual supplies of ±4.5V to ±20V or a single supply of +9V to +36V. The device provides ±40V overvoltage protection when powered off and ±25V protection when powered on, clamping the output to the appropriate supply rail during faults. Key electrical parameters include a maximum on-resistance of 400 Ω, an on-resistance match between channels of 15 Ω max, and a fault response time of 20 ns. Logic inputs are TTL/CMOS compatible.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Fault-protected analog signal handling with rail-to-rail capability

TTL and CMOS logic input compatibility without power-supply sequencing

Analog Switches, Multiplexers, Demultiplexers Applications

Data-acquisition systems
Industrial and process control
Avionics signal routing
Redundant and backup systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component designation against official manufacturer documentation to confirm the specific suffix indicates lead-free construction and the extended temperature range. Ensure that the ordering information matches the required pin configuration and thermal specifications for the intended application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high-voltage fault tolerance and rail-to-rail signal integrity. Verify that the supply voltage range aligns with the system's power architecture. Confirm that the logic thresholds meet the driving interface requirements for both TTL and CMOS sources.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4508/MAX4509 family of fault-protected multiplexers. It serves as the dual-channel variant (MAX4509) compared to the single-channel MAX4508. Both share identical pinouts and fault-protection mechanisms while differing in channel count and internal decoding logic.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin compatibility with industry-standard DG508/DG509 devices. Verify functional equivalence regarding fault protection levels and on-resistance before substitution.
