MAX4508ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4508ESE+T is a single 8-to-1 fault-protected 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 supplies on. Key electrical parameters include a maximum on-resistance of 400 Ω, an on-resistance match between channels of 15 Ω max, and a fault output clamp turn-on delay of 20 ns. The enable turn-on time is typically 170 ns, while the enable turn-off time is 250 ns. It utilizes TTL/CMOS-compatible logic inputs and is housed in a 16-pin Narrow SO package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'ESE+T' against official documentation to confirm the extended temperature range (-40°C to +85°C), narrow SOIC package type, and tape-and-reel packaging format. Ensure compatibility with system voltage requirements and logic thresholds before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high-voltage fault protection and rail-to-rail signal handling. Verify that the required analog signal range falls within the specified limits relative to the chosen supply voltages. Confirm that the logic input levels are compatible with the system's digital interface.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4508/MAX4509 family of fault-protected multiplexers. The MAX4508 variant provides a single 8-to-1 configuration, whereas the MAX4509 offers a dual 4-to-1 arrangement. Both share pin compatibility with industry-standard DG508/DG509 devices.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin compatibility with DG508/DG509. Verify functional equivalence regarding fault protection levels and on-resistance specifications before substitution.
