MAX354CWE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX354CWE+ is a single-channel fault-protected analog multiplexer housed in a 16-Wide SOIC package. It features an on-resistance of 350 Ω maximum and operates from dual supplies ranging from ±4.5V to ±18V or a single supply up to 36V. The device provides overvoltage protection up to 40V beyond the supply rails during power-up, power-down, and fault conditions. Input leakage current is less than 0.5nA at +25°C and 5nA at +85°C. It supports break-before-make switching with a typical transition time of 180ns and requires no power-up sequencing.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Series N-channel, P-channel, N-channel structure protects against overvoltages up to 40V beyond supply rails.
• Break-before-make operation prevents input-to-input shorts during switching.
• TTL and CMOS logic compatibility without requiring pull-up resistors.
• All switches turn off automatically when power supplies are removed.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CWE+' corresponds to the Wide SOIC package and commercial temperature range (0°C to +70°C). Confirm RoHS compliance status as indicated by the '+' designation. Ensure the ordering quantity matches the manufacturer's standard tube packaging specifications for this package type.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX354CWE+ for applications requiring a single 8:1 multiplexer configuration. Consider the MAX355 variant if a dual 4:1 configuration is needed. Verify that the required signal voltage range stays within the fault-protection limits and that the 350Ω on-resistance meets system impedance requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX354/MAX355 family of fault-protected analog multiplexers manufactured by Analog Devices Inc./Maxim Integrated. It serves as an improved second source for older models like the MAX358/MAX359 and DG458/DG459. The part is pin-compatible with ADI's ADG508F/ADG509F series.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the device handle overvoltage when power is off?

The series FET protection scheme limits input current to sub-microamp levels and prevents signals from reaching the output even when V+ and V- are absent, protecting against voltages up to 40V.

What is the break-before-make interval?

The device guarantees a break-before-make interval of approximately 100ns to prevent simultaneous connection of two input channels to the output.

Can the MAX354 operate with a single supply?

Yes, it can operate with a single supply from +4.5V to +30V by connecting the V- pin to ground (0V).
