Analog Devices Inc./Maxim Integrated MAX339CEE+

Overview

MAX339CEE+ from Maxim Integrated is a dual 4-channel CMOS analog multiplexer designed to route one of four bidirectional analog inputs per section (NO1A–NO4A and NO1B–NO4B) to respective common outputs (COMA and COMB) under 2-bit binary address control (A0, A1). It features ≤400Ω on-resistance, <20pA NO-off leakage at +25°C, 1.5pC typical charge injection, and operates from ±4.5V to ±20V or +4.5V to +30V supplies. It serves in precision data-acquisition systems requiring low signal distortion and rail-to-rail analog handling.

For engineers reviewing the MAX339CEE+ datasheet, MAX339CEE+ pinout, MAX339CEE+ application, or MAX339CEE+ equivalent, key selection criteria include guaranteed low leakage across temperature, TTL/CMOS-compatible enable/address inputs, dual- or single-supply flexibility, ESD protection >2000V, and pin-compatibility with industry-standard DG509A for drop-in upgrades in test equipment and military radios.

Technical Context

The MAX339CEE+ implements fully bidirectional CMOS switch architecture with independent decode logic for each 4-channel section, enabling simultaneous or separate channel selection. Its silicon-gate 44V process ensures robust operation across ±4.5V to ±20V bipolar supplies or +4.5V to +30V single supply (V− tied to GND), with rail-to-rail analog signal range up to ±15V.

All digital inputs-including EN, A0, and A1-are TTL/CMOS-compatible over full temperature range and supply voltage (±4.5V to ±18V), with input thresholds fixed at +0.8V (logic low) and +2.4V (logic high). Break-before-make timing is guaranteed ≤140ns at +25°C, minimizing transient crosstalk during channel switching.

Key Specifications

Pinout & Package

MAX339CEE+ is housed in a 16-pin QSOP (Quad Small Outline Package) with 0.65mm lead pitch, RoHS-compliant and lead-free. The package provides compact footprint and thermal performance suitable for space-constrained industrial PCBs.

FAQ

What is the maximum allowable supply voltage difference for MAX339CEE+?

The MAX339CEE+ specifies an absolute maximum V+ to V− differential of 44V. Operation beyond this risks permanent damage. For reliable long-term use, maintain V+ − V− ≤ 40V, especially at elevated temperatures. The device supports asymmetric supplies (e.g., +24V/−5V) as long as the difference stays within limit and individual rails remain within their absolute ratings (V+ ≤ +44V, V− ≥ −0.3V relative to GND). Always verify power sequencing: V+ first, then V−, then logic inputs.

Does MAX339CEE+ support single-supply operation, and how is it configured?

Yes, MAX339CEE+ supports single-supply operation from +4.5V to +30V. To configure, tie V− to GND and apply the positive supply to V+. Analog signals may swing from 0V to V+, enabling compatibility with microcontroller-based systems and unipolar sensors. Note that on-resistance increases slightly versus dual-supply mode (e.g., 650Ω max at +12V), and dynamic parameters like transition time degrade marginally-verify timing margins in your specific application.

What is the guaranteed leakage current specification for MAX339CEE+ over its full temperature range?

For MAX339CEE+ (0°C to +70°C grade), NO-off leakage is guaranteed ≤±1.25nA over temperature, and COM-off leakage is guaranteed ≤±1.65nA over temperature-both tested at maximum rated hot temperature and correlated at +25°C. These values reflect worst-case parametric limits, not typicals. At +25°C, leakage is typically <0.005nA, supporting high-impedance applications such as piezoelectric sensor interfaces and electrophysiology front-ends.

Is MAX339CEE+ pin-compatible with DG509A, and what design changes are needed for replacement?

Yes, MAX339CEE+ is explicitly documented as a pin-compatible upgrade for DG509A, sharing identical 16-pin QSOP pinout and logic-level behavior. No PCB changes are required. However, due to lower on-resistance (400Ω vs. 600Ω) and reduced charge injection (1.5pC vs. 10pC), system-level timing and settling behavior may improve-verify stability in feedback loops and recalibrate if used in precision gain-setting paths. ESD robustness (>2000V) also exceeds DG509A, enhancing field reliability.

What is the minimum logic high voltage required to reliably enable MAX339CEE+ at full temperature range?

The MAX339CEE+ guarantees TTL/CMOS-compatible inputs across its full 0°C to +70°C operating range: logic high (V_IH) is defined as ≥+2.4V, and logic low (V_IL) as ≤+0.8V, regardless of supply voltage (±4.5V to ±18V). This means EN, A0, and A1 will reliably assert at +2.4V even at temperature extremes. Driving these pins from standard 3.3V or 5V logic families requires no level shifting-direct connection suffices for robust operation in industrial control and avionics environments.
