MAX4508ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4508ESE+ is a single 8-to-1 fault-protected analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates with dual supplies of ±4.5V to ±20V or a single supply of +9V to +36V. The device features ±40V overvoltage protection with power off and ±25V protection with power on. Key electrical parameters include a maximum on-resistance (RON) of 400 Ω, an on-resistance match (ΔRON) of 15 Ω max, and a fault output clamp turn-on delay of 20 ns. The component is housed in a 16-pin Narrow SO package and supports 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 the exact temperature grade and package variant. Ensure that the selected part number matches the required operational voltage range and pin configuration for your specific circuit design before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-voltage fault protection and rail-to-rail signal handling are required. Verify that the system's analog signal levels remain within the specified fault-protected ranges relative to the chosen supply voltages. Confirm compatibility with TTL or CMOS logic thresholds for the control interface.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4508/MAX4509 family of fault-protected, high-voltage multiplexers. The MAX4508 variant provides a single 8-to-1 configuration, while the MAX4509 offers a dual 4-to-1 setup. Both share similar fault protection characteristics and are designed for robust signal routing in demanding environments.
