MAX4709EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4709EPE is a dual 4-to-1 fault-protected multiplexer housed in a 16-pin Plastic DIP package. It operates with dual supplies from ±4.5V to ±20V or a single supply from +9V to +36V, covering an industrial temperature range of -40°C to +85°C. The device features a maximum on-resistance of 400Ω at ±15V and 950Ω at +12V single supply, with channel matching up to 15Ω and 35Ω respectively. Fault protection allows ±40V input when powered off and ±36V when powered on. Logic inputs are TTL/CMOS compatible, requiring 2.4V for high and 0.8V for low thresholds.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Provides fault protection by disconnecting the output during overvoltage conditions without clamping to supply rails
• Supports rail-to-rail signal handling capability across the full supply voltage range
• Eliminates the need for power-supply sequencing during operation
• Features TTL and CMOS-compatible logic input thresholds

Analog Switches, Multiplexers, Demultiplexers Applications

• Data-acquisition systems
• Industrial and process control applications
• Avionics signal routing
• Redundancy and backup systems
• Automated test equipment (ATE)

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EPE confirms the 16-pin Plastic DIP package variant. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Check current lifecycle status as the component may be discontinued. Ensure environmental compliance data matches project requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring robust fault protection against voltages exceeding supply rails. Verify that the 400Ω on-resistance meets system signal integrity requirements. Ensure the 16-pin DIP footprint aligns with the PCB layout constraints. Consider the ±40V fault tolerance if operating in harsh electrical environments.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4708/MAX4709 family of fault-protected multiplexers. It serves as a pin-compatible replacement for industry-standard DG508/DG509 devices. Unlike previous generations such as the MAX4508/MAX4509, it utilizes parallel FETs for improved flatness and avoids output clamping during faults.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4708EPE is the single-channel 8-to-1 equivalent within the same series. Direct pin-compatible alternatives include the DG508 and DG509 legacy parts.
