MAX4708EPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4708EPE+ is a fault-protected, single 8-to-1 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 with a channel matching of 15Ω. It provides ±40V overvoltage protection when supplies are off and ±36V when supplies are active. Logic inputs are TTL/CMOS compatible. The component is housed in a 16-pin Plastic DIP package and functions across an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm pin compatibility and package type. Confirm RoHS compliance status through current datasheets. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high-voltage fault protection and rail-to-rail signal transmission. Verify that the load configuration on the COM_ pin does not exceed the absolute maximum ratings. Consider the break-before-make timing and fault recovery characteristics when designing fast-switching circuits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4708/MAX4709 series of fault-protected multiplexers. It serves as a pin-compatible replacement for industry-standard DG508/DG509 devices. Unlike older designs, it utilizes parallel FETs for lower on-resistance and improved signal flatness while eliminating clamp diodes to the supply rails on switch outputs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4708EPE+ is functionally equivalent to the DG508. Other variants in the same family include MAX4708ESE and MAX4708EWE, which share identical electrical characteristics but differ in packaging format.
