MAX339EEE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX339EEE+T is a dual, 4-channel CMOS analog multiplexer housed in a 16-pin QSOP package. It connects one of four inputs to a common output via a 2-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. Leakage currents are extremely low, with off-leakage less than 20pA at +25°C. The part supports TTL-compatible logic inputs and features ESD protection exceeding 2000V.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum on-resistance of the MAX339EEE+T?

The maximum on-resistance is 400Ω at +25°C and 500Ω across the full specified temperature range.

How does the MAX339EEE+T handle overvoltage conditions?

Signals on NO, COM, EN, A0, A1, or A2 exceeding V+ or V- are clamped by internal diodes. External blocking diodes can be added for additional protection if power-supply sequencing is not possible.

Is the MAX339EEE+T compatible with TTL logic levels?

Yes, all control inputs are TTL compatible (+0.8V to +2.4V) over the full specified temperature range and over the ±4.5V to ±18V supply range.
