MAX354CWE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX354CWE+T is a single-channel, 8-to-1 fault-protected analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply of 4.5V to 36V or dual supplies of ±4.5V to ±18V. The device features a maximum on-resistance of 350Ω and input leakage current below 0.5nA at +25°C. Digital inputs are compatible with TTL and CMOS logic without pull-up resistors. It provides break-before-make switching and protects against overvoltages up to 40V beyond the supply rails during power-up, power-down, and fault conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component status as discontinued through official manufacturer channels before finalizing procurement plans. Confirm that the Wide SOIC-16 package meets the physical footprint requirements of the target PCB design. Ensure that the operating temperature range aligns with the environmental specifications of the intended application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high-voltage fault tolerance and low leakage currents. Verify that the required signal voltage range remains within the safe operating limits defined by the supply voltages. Consider the 350Ω on-resistance impact on signal integrity in high-impedance circuits. Ensure the digital interface logic levels match the system's control voltage standards.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX354/MAX355 family of fault-protected analog multiplexers. The MAX354 variant provides a single 8-channel configuration, whereas the MAX355 offers dual 4-channel configurations. Both share identical pinouts and core protection circuitry, allowing for flexible design implementations across different channel count requirements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX354CWE+T is pin-compatible with the ADG508F. Designers may also consider the MAX358 and MAX359 as improved second-source alternatives within the same product family.
