MAX338ETE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX338ETE is a monolithic CMOS analog multiplexer featuring eight independent channels configured as a single 8:1 switch. It connects one of eight inputs to a common output via a 3-bit binary address. The device operates from a single supply voltage ranging from +4.5V to +30V or dual supplies of ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 400Ω, typical charge injection of 1.5pC, and off-leakage current below 20pA at +25°C. Control inputs are TTL compatible across the full temperature range. The component is housed in a 16-pin QSOP package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Provides an 8-channel analog switching solution with low on-resistance for signal routing applications.
• Features extremely low off-state leakage currents to minimize signal distortion when switches are open.
• Includes electrostatic discharge protection exceeding 2000V per specified testing methods.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring multi-channel signal selection.
• Process control instrumentation involving analog signal routing.
• Automotive test equipment utilizing high-voltage single-supply operation.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix ETE against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 16-lead QSOP format. Check for end-of-life status or obsolescence notices prior to finalizing design-in decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel mux with low leakage is required. Compare on-resistance specifications against other Maxim devices like the MAX328 if lower resistance is needed, noting potential trade-offs in leakage performance. Confirm that the 400Ω max Ron meets the application's voltage drop requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX338ETE belongs to the MAX338/MAX339 family of analog multiplexers manufactured by Analog Devices (Maxim Integrated). This series serves as a pin-compatible upgrade for industry-standard parts such as the DG508A. The family is characterized by CMOS construction and robust ESD protection capabilities.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX338EPE+ and MAX338ESE+ are direct functional equivalents within the same product line, differing primarily in packaging style (PDIP and SOIC respectively) rather than internal circuitry. Verify pinout compatibility before substitution.
