MAX338ETE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX338ETE+ is an 8-channel CMOS analog multiplexer in a 16-pin TQFN-EP (5mm x 5mm) package. It operates from single supplies of +4.5V to +30V or dual supplies of ±4.5V to ±20V. The device features a maximum on-resistance of 400Ω at +25°C and 500Ω across the full temperature range (-40°C to +85°C). Off-leakage current is less than 20pA at +25°C, with typical charge injection of 1.5pC. Control inputs are TTL compatible (+0.8V to +2.4V). ESD protection exceeds 2000V per method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix ETE+ corresponds to the 16-pin TQFN-EP package variant. Confirm that the lead-free/RoHS-compliant designation matches project requirements. Check for any recent product change notices regarding availability or manufacturing location updates before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low leakage and precise switching are required. Ensure the analog signal range fits within the chosen supply voltage limits. Verify that the 500ns transition time meets system timing constraints. Consider thermal dissipation capabilities if operating near maximum power ratings.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX338/MAX339 family of monolithic CMOS analog multiplexers. It serves as a pin-compatible upgrade for industry-standard DG508A devices. The MAX338 provides eight channels, while the MAX339 offers two dual four-channel configurations. Both share similar electrical characteristics and control logic interfaces.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX338EPE+ is a PDIP-16 alternative within the same series. For lower leakage but higher on-resistance needs, consider the MAX328. Direct pin-compatible replacements include the DG508A. Verify package dimensions and thermal pad connections when substituting.
