MAX338CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX338CSE+ is an 8-channel CMOS analog multiplexer in a 16-pin Narrow SO package. It connects one of eight inputs to a common output via a 3-bit binary address. The device operates from single +4.5V to +30V or dual ±4.5V to ±20V supplies. Key electrical parameters include a maximum on-resistance of 400Ω at +25°C and 500Ω across the full temperature range, with channel matching of 4Ω typical. Off-leakage current is less than 20pA at +25°C, and charge injection is typically 1.5pC. Control inputs are TTL compatible.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE+' corresponds to the commercial temperature range (0°C to +70°C) and the 16-pin Narrow SO package configuration. Confirm RoHS compliance status as indicated by the plus sign. Ensure the ordering part number matches the exact pinout and voltage requirements for your design before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel analog switch with low leakage and moderate on-resistance is required. It serves as a direct upgrade for older DG508A designs. Consider the MAX339 if only four channels are needed, or the MAX328/MAX329 if lower leakage is prioritized over higher on-resistance. Verify supply voltage compatibility with single or dual rail configurations.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX338/MAX339 family of monolithic CMOS analog multiplexers manufactured by Analog Devices/Maxim Integrated. The MAX338 variant specifically provides eight single-ended channels controlled by three address bits. It is designed for applications requiring reliable analog signal routing with minimal signal distortion due to its low charge injection characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX338CSE+ is a pin-compatible upgrade for the DG508A. For equivalent functionality within the same manufacturer's portfolio, consider the MAX338ESE+ for extended temperature ranges or the MAX338CEE+ for QSOP packaging.
