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 analog inputs per section to a common bidirectional output under 2-bit binary address control. It features ≤400Ω on-resistance, <20pA off-leakage at +25°C, and 1.5pC typical charge injection, enabling precision signal routing in data-acquisition and test equipment.

For engineers reviewing the MAX339CEE datasheet, MAX339CEE pinout, MAX339CEE application, or MAX339CEE equivalent, key selection criteria include guaranteed low leakage across temperature, rail-to-rail analog signal handling (±20V dual / +30V single supply), TTL/CMOS-compatible control inputs, and ESD protection >2000V per Method 3015.7.

Technical Context

The MAX339CEE implements two independent 4:1 analog multiplexers in a single monolithic CMOS die using Maxim's 44V silicon-gate process. Each section decodes A1/A0 address bits to select one of four bidirectional NOx inputs to its COMx output, with separate EN enable control per section.

It supports both single-supply (+4.5V to +30V) and dual-supply (±4.5V to ±20V) operation, with all digital inputs TTL-compatible over full temperature range and supply voltage. Signal paths handle rail-to-rail voltages, and internal clamping diodes protect against overvoltage on NO, COM, and control pins.

Key Specifications

Pinout & Package

The MAX339CEE is housed in a 16-pin narrow SOIC (Small Outline Integrated Circuit) package with standard 1.27mm pitch and gull-wing leads. Pin 1 is marked by a beveled corner or dot; the exposed pad is not present in this variant.

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog multiplexer applications.

Compared with DG509A, MAX339CEE delivers superior leakage, charge injection, and ESD robustness in identical pinout; compared with MAX329CSE, it trades higher on-resistance for significantly better signal fidelity and drive capability in general-purpose precision routing.

FAQ

What is the operating temperature range of the MAX339CEE?

The MAX339CEE is rated for commercial temperature operation from 0°C to +70°C. This range is confirmed in the Ordering Information table, where "MAX339CEE" maps to the "C" grade suffix and "0°C to +70°C" specification. The device uses Maxim's 44V silicon-gate process and is tested across this full range for parameters including on-resistance, leakage, and switching timing.

Does the MAX339CEE support single-supply operation?

Yes, the MAX339CEE supports single-supply operation from +4.5V to +30V. Per the Electrical Characteristics tables and Applications Information section, V− must be connected to GND in this configuration. The analog signal range extends rail-to-rail (0V to V+), and all control inputs remain TTL-compatible across the full supply range.

Is the MAX339CEE pin-compatible with the DG509A?

Yes, the MAX339CEE is explicitly documented as a pin-compatible upgrade for the DG509A. The General Description states: "These improved muxes are pin-compatible upgrades for the industry-standard DG509A." Pin mapping, package outline, and terminal functions match exactly for the 16-pin DIP and SO packages, enabling drop-in replacement without PCB modification.

What is the maximum analog signal voltage the MAX339CEE can handle?

The MAX339CEE handles analog signals from V− to V+ - i.e., rail-to-rail. With ±20V dual supplies, the full range is ±20V; with +30V single supply, it is 0V to +30V. Absolute Maximum Ratings confirm NO and COM terminals tolerate (V− − 2V) to (V+ + 2V), but functional operation is limited to the supply rails per the Analog Signal Range specification.

How does charge injection affect system accuracy in MAX339CEE-based designs?

Charge injection of 1.5pC typical in the MAX339CEE causes a voltage step ΔV = Q/CL on the downstream capacitance (e.g., ADC input cap or sample-hold capacitor). For a 100pF load, this yields 15mV glitch - manageable with proper settling time or filtering. In precision systems, this value directly determines minimum usable sampling frequency and achievable ENOB, especially in multiplexed ADC architectures.
