Analog Devices Inc./Maxim Integrated MAX339CEE+T

Overview

The MAX339CEE+T 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 max on-resistance, <20pA NO-off leakage at +25°C, and 1.5pC typical charge injection-enabling precision signal routing in data-acquisition systems operating from ±4.5V to ±20V or +4.5V to +30V supplies.

For engineers reviewing the MAX339CEE+T datasheet, MAX339CEE+T pinout, MAX339CEE+T application, or MAX339CEE+T equivalent, key selection criteria include guaranteed low leakage across temperature, rail-to-rail analog signal handling (±15V), TTL/CMOS-compatible enable and address inputs, and ESD protection >2000V per Method 3015.7.

Technical Context

The MAX339CEE+T implements fully bidirectional CMOS switch architecture with independent decode logic for two 4-channel sections (COMA/NO1A–NO4A and COMB/NO1B–NO4B). Each section uses separate A0/A1 address lines and shared EN, supporting simultaneous or independent channel selection.

It operates across dual supplies (±4.5V to ±20V) or single supply (+4.5V to +30V), with all digital inputs TTL-compatible over full temperature range and supply voltage. Fabricated in Maxim's 44V silicon-gate process, it guarantees break-before-make timing (10–140ns) and transition time <500ns at +25°C.

Key Specifications

Pinout & Package

MAX339CEE+T is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.15mm lead thickness, 3.9mm body width, and 1.0mm pitch. The package is RoHS-compliant and lead(Pb)-free.

Equivalent & Alternatives

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

Compared with MAX339CEE+T, MAX329CPE+ trades higher on-resistance for drastically lower leakage-making it optimal for femtoamp-level measurements-while ADG408BRUZ offers lower RON and smaller footprint but lacks native dual-section control, increasing firmware complexity in synchronized dual-path applications.

FAQ

What is the maximum supply voltage rating for MAX339CEE+T?

The MAX339CEE+T supports dual supplies from ±4.5V to ±20V or a single supply from +4.5V to +30V. Absolute maximum ratings specify V+ to V− ≤ 44V, with V+ limited to 44V above ground and V− to -0.3V minimum. Exceeding these stresses may cause permanent damage, and operation beyond ±20V or +30V is not guaranteed.

Does MAX339CEE+T support rail-to-rail analog signal switching?

Yes, the MAX339CEE+T supports rail-to-rail analog signal switching-signals at NOx and COM terminals can swing from V− to V+ without degradation. This is confirmed in the Electrical Characteristics table under "Analog Signal Range" (±15V with ±15V supplies) and applies across the full specified temperature range when operated within supply limits.

Is MAX339CEE+T pin-compatible with industry-standard alternatives?

Yes, the MAX339CEE+T is explicitly documented as a pin-compatible upgrade for the DG509A. Pin functions-including A0/A1, EN, COMA/COMB, NO1A–NO4A/NO1B–NO4B, V+, V−, and GND-match the DG509A in 16-pin PDIP, SO, and QSOP packages. No PCB changes are required for drop-in replacement.

What is the guaranteed charge injection specification for MAX339CEE+T?

The MAX339CEE+T has a guaranteed charge injection of 1.5pC typical (5pC max) under test conditions of CL = 100pF, VNO = 0V, and RS = 0Ω. This value is measured and specified in the Electrical Characteristics table and directly impacts settling time and accuracy in sample-and-hold and switched-capacitor applications.

How does MAX339CEE+T handle power-supply sequencing?

The MAX339CEE+T recommends sequencing V+ first, then V−, followed by logic inputs (EN, A0, A1). If strict sequencing isn't feasible, external blocking diodes can be added to V+ and V− pins-reducing analog range by 1V but preserving low leakage and on-resistance. This guidance is provided in the Applications Information section of the datasheet.
