MAX350EAP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX350EAP is a dual 4-channel serially controlled multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates with dual power supplies ranging from ±2.7V to ±8V or a single supply between +2.7V and +16V. The device features an SPI/QSPI/MICROWIRE-compatible serial interface, rail-to-rail signal handling, and >2kV ESD protection. It includes an asynchronous RESET input and TTL/CMOS-compatible digital inputs. The extended temperature grade (E) supports operation from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package type associated with the 'A' suffix in the official Maxim Integrated datasheet before procurement. Confirm that the ordering suffix accurately reflects the required operating temperature range and physical footprint for your design constraints.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-channel multiplexer with serial control is required. Ensure the application voltage falls within the specified single or dual supply ranges. Verify that the system logic levels are compatible with the device's TTL/CMOS input thresholds.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX349/MAX350 family of low-voltage multiplexers. While the MAX349 provides a single 8-to-1 mux, the MAX350 offers two independent 4-to-1 muxes. Both share identical serial interface protocols and electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX349 serves as a functional alternative if a single 8-channel multiplexer is sufficient for the application. Verify pinout compatibility and channel count requirements before substitution.
