MAX338CEE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX338CEE+ is an 8-channel CMOS analog multiplexer from the MAX338/MAX339 family, designed to connect one of eight inputs to a common output via a 3-bit binary address. It operates on single supplies from +4.5V to +30V or dual supplies from ±4.5V to ±20V. The device features a maximum on-resistance of 650Ω at +25°C and 500Ω across the full temperature range. Off-leakage current is less than 20pA at +25°C, with typical charge injection of 1.5pC. It provides over 2000V ESD protection per method 3015.7 and includes TTL-compatible control inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CEE+ confirms the commercial temperature range (0°C to +70°C) and 16-pin QSOP package configuration. Confirm lead-free/RoHS compliance status as indicated by the plus sign in the part number. Ensure the ordering documentation matches the exact pinout and functional specifications provided in the official datasheet.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low leakage and high isolation are critical requirements. It serves as a pin-compatible upgrade for industry-standard DG508A devices. Consider the MAX328 if lower leakage is needed despite higher on-resistance. Verify that the required analog signal range fits within the specified supply voltage limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX338/MAX339 series of monolithic CMOS analog multiplexers. The MAX338 variant specifically handles 8 channels, while the MAX339 handles dual 4-channel configurations. Both share similar electrical characteristics and are fabricated using Maxim’s 44V silicon-gate process technology.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX338CEE+ is a direct pin-compatible replacement for the DG508A. For applications requiring lower leakage but accepting higher on-resistance, the MAX328 may be considered.
