MAX394CWP+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX394CWP+ is a low-voltage, quad single-pole/double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates with bipolar supplies from ±2.7V to ±8V or a single supply of +2.7V to +15V. The device features an on-resistance of less than 35Ω at ±4.5V and guarantees channel matching within 2Ω. It provides break-before-make switching with turn-off times under 75ns and turn-on times under 130ns. Quiescent current remains below 1μA. Logic inputs are compatible with TTL and CMOS standards.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Supports both single-supply (+2.7V to +15V) and dual-supply (±2.7V to ±8V) operation for flexible system integration.
• Features rail-to-rail analog signal handling capability, allowing signals to range between supply voltages without damage.
• Ensures extremely low charge injection (10pC typical) and high electrostatic discharge protection exceeding 2000V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CWP+' against official documentation to confirm the wide SOIC-20 package and commercial temperature range (0°C to +70°C). Ensure that any ordering suffixes do not alter the functional specifications unless explicitly stated in the manufacturer's datasheet. Cross-reference the component with authorized distributors to validate authenticity and traceability before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPDT configuration with low on-resistance and rail-to-rail signal handling is required. It serves as a direct pin-compatible replacement for the MAX333 and MAX333A. Consider the ±2.7V to ±8V dual supply or +2.7V to +15V single supply limits during design. Verify logic input compatibility requirements, as they vary slightly depending on whether the supply voltage exceeds +8V.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX394 series includes variants such as MAX394CPP, MAX394EPP, and MAX394MJP, covering different temperature ranges and packages. The C-series denotes commercial grade (0°C to +70°C), while the E-series covers extended temperatures (-40°C to +85°C). The MAX394CWP+ specifically utilizes a 20-pin Wide SO package. This family is designed for portable applications due to its ultra-low quiescent current consumption.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX394CWP+ is pin-compatible with the MAX333 and MAX333A. Designers replacing these older components should verify that the new part meets the specific on-resistance and leakage requirements of the original circuit design.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the logic input voltage range change with supply voltage?

For supply voltages up to +8V, logic inputs are guaranteed over a +0.8V to +2.4V range. When supplies exceed +8V, the inputs are typically +0.8V to +4V.

What is the maximum power dissipation for the Wide SO package?

The continuous power dissipation for the Narrow SO (Wide SO) package is 696mW at TA = +70°C, derating by 8.70mW/°C above +70°C.

Does the MAX394 support break-before-make switching?

Yes, the device offers break-before-make switching with a typical time delay of 10ns.
