MAX338EEE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX338EEE+ is an 8-channel CMOS analog multiplexer in a 16-pin QSOP package. It connects one of eight inputs to a common output via a 3-bit binary address. The device operates from single supplies of +4.5V to +30V or dual supplies of ±4.5V to ±20V. 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. Off-leakage current is less than 20pA at +25°C. Dynamic characteristics feature a maximum transition time of 500ns, enable turn-on/off times of 500ns, and typical charge injection of 1.5pC. Control inputs are TTL compatible.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized channels as the MAX338EEE+ is marked as obsolete by Analog Devices Inc./Maxim Integrated. Confirm RoHS compliance status for lead-free packaging requirements. Check datasheet revision history for any parameter updates. Ensure proper handling due to CMOS sensitivity. Validate pin compatibility if replacing legacy components like DG508A.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low leakage and guaranteed charge injection are critical. It serves as a pin-compatible upgrade for industry-standard DG508A devices. Consider the MAX328/MAX329 if lower leakage is required despite higher on-resistance. Verify that the 400Ω on-resistance meets signal integrity requirements for the specific application voltage levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX338EEE+ belongs to the MAX338/MAX339 family of monolithic CMOS analog multiplexers. The MAX338 variant provides 8 single-ended channels, while the MAX339 offers dual 4-channel configurations. Both share identical pinouts and core switching technologies, allowing flexible design implementations for various multiplexing or demultiplexing needs within industrial and military environments.
