MAX4708ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4708ESE+ is a single 8-to-1 fault-protected multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of +9V to +36V (single) or ±4.5V to ±20V (dual). The device features a maximum on-resistance of 400Ω and an on-resistance match between channels of 15Ω. Fault protection allows ±40V overvoltage with supplies off and ±36V with supplies on. Logic inputs are TTL/CMOS compatible. The package is a 16-pin Narrow SOIC, operating from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Rail-to-rail signal handling capability without requiring power-supply sequencing
• Fault-protected analog inputs that disconnect during overvoltage conditions
• 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
• Redundancy and backup systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix ESE corresponds to the 16-pin Narrow SOIC package and the industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure pinout compatibility with existing designs referencing industry-standard DG508/DG509 layouts.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-voltage fault protection is required at the analog input terminals. Verify that the maximum on-resistance of 400Ω meets the signal integrity requirements of the application. Ensure the supply voltage does not exceed the absolute maximum ratings of 44V differential. Consider the dual 4-to-1 variant if two independent channels are needed instead of a single 8-to-1 path.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4708/MAX4709 family of fault-protected multiplexers. It serves as a direct pin-compatible replacement for the industry-standard DG508/DG509 devices. Unlike older designs such as the MAX4508/MAX4509, it utilizes parallel FETs for lower on-resistance and disconnects rather than clamping during faults.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4708EPE+ (Plastic DIP) and MAX4708EWE+ (Wide SO) offer identical electrical performance in different packages. For dual-channel applications, the MAX4709ESE+ provides equivalent fault protection in a 4-to-1 configuration.
