MAX4709ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4709ESE+T is a dual 4-to-1 fault-protected multiplexer in a 16-pin Narrow SO package. It operates on single supplies from +9V to +36V or dual supplies of ±4.5V to ±20V. The device provides ±40V overvoltage protection with power off and ±36V with power on. Key electrical parameters include a maximum on-resistance of 400Ω, 15Ω channel matching, and 525µA maximum supply current. Switching characteristics feature a maximum enable turn-on time of 400ns and an off-isolation of -70dB at 1MHz.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Rail-to-rail signal handling capability without requiring power-supply sequencing
• Fault-protected inputs that disconnect during overvoltage events to maintain high impedance
• TTL and CMOS logic-compatible digital inputs for versatile control integration

Analog Switches, Multiplexers, Demultiplexers Applications

• Data-acquisition systems
• Industrial and process control
• Avionics signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature range. Ensure compatibility with existing board layouts by checking pin configurations. Confirm RoHS compliance status through authorized distributors before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is required for analog signals exceeding supply rails. Verify that the 400Ω on-resistance meets system loss requirements. Consider the dual 4-to-1 configuration versus the single 8-to-1 variant based on channel count needs.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4708/MAX4709 family of fault-protected multiplexers. It serves as a direct replacement for industry-standard DG509 devices while offering enhanced rail-to-rail performance and improved flatness compared to older designs like the MAX4509.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4709EWE is a wide SOIC alternative within the same family. Direct functional substitutes include the DG509. Verify pinout compatibility and on-resistance specifications when cross-referencing with other manufacturers' offerings.
