Product details
Overview
The MAX339MSE/PR3+ from Maxim Integrated is a dual 4-channel CMOS analog multiplexer designed to route one of four analog inputs per section (NO1A–NO4A and NO1B–NO4B) to respective bidirectional common outputs (COMA and COMB) under 2-bit binary address control (A0, A1), with independent enable (EN). It features ≤400Ω on-resistance, <20pA NO-off leakage at +25°C, 1.5pC typical charge injection, rail-to-rail signal handling (±15V dual or +12V single supply), and operates across -55°C to +125°C for high-reliability military and aerospace data-acquisition systems.
For engineers reviewing the MAX339MSE/PR3+ datasheet, MAX339MSE/PR3+ pinout, MAX339MSE/PR3+ application, or MAX339MSE/PR3+ equivalent, key selection criteria include guaranteed low-leakage performance over extended temperature, TTL/CMOS-compatible control logic, ESD protection >2000V, pin-compatible upgrade path from DG509A, and validated operation in guidance-and-control signal routing where channel crosstalk (<-92dB) and break-before-make timing (10–140ns) are critical.
Technical Context
The MAX339MSE/PR3+ implements two independent 4:1 analog multiplexers in a single monolithic CMOS die using Maxim's 44V silicon-gate process. Each section decodes A0/A1 to select one of four bidirectional analog paths, with EN enabling/disabling both sections simultaneously. Control inputs tolerate ±4.5V to ±18V supply rails and maintain TTL compatibility (0.8V–2.4V thresholds) across full temperature range.
Signal switching relies on low-threshold transmission gates with matched on-resistance (≤10Ω channel-to-channel variation) and tightly controlled charge injection (1.5pC typ) to minimize sampling error in precision sample-and-hold circuits. Off-isolation exceeds -75dB at 100kHz, and crosstalk between active/inactive channels remains below -92dB - critical for multi-channel test equipment avoiding signal coupling artifacts.
Key Specifications

| 11 | COMB | Common output (Section B): independent bidirectional node for second 4:1 mux section; enables dual-path signal routing. |
| 12 | GND | Digital ground reference: provides return path for logic inputs and internal decode circuitry; separate from analog signal grounds. |
| 13 | V+ | Positive supply rail input: supplies core analog switch array and logic; must be ≥|V−| + 4.5V for stable operation. |
| 14 | A1 | Address bit 1: MSB of 2-bit binary selector for both mux sections; TTL/CMOS compatible (0.8V–2.4V valid range). |
| 15 | A0 | Address bit 0: LSB of 2-bit binary selector; simultaneous decoding controls both Section A and Section B. |
| 16 | EN | Enable input: active-high logic control; disables both mux sections when low, placing all NOx and COMx terminals in high-impedance off-state. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-channel analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG509A | Higher on-resistance (600Ω max), higher charge injection (10pC), no guaranteed ESD rating | Limited to commercial-grade test gear; unsuitable for extended temperature or high-reliability mil-aero use | Legacy drop-in where MAX339MSE/PR3+ qualification is not required and leakage/ESD are non-critical |
| MAX329ESE+ | Lower leakage (<5pA off), lower charge injection (0.5pC), but higher on-resistance (800Ω max) | Better for ultra-high-impedance pH or radiation sensor front-ends; worse for low-gain-error signal chains | Select when sub-10pA leakage dominates design priority over on-resistance-induced gain error |
Compared with DG509A and MAX329ESE+, the MAX339MSE/PR3+ delivers optimal balance of low leakage, low charge injection, and moderate on-resistance across -55°C to +125°C - making it the preferred choice for military-grade data acquisition where all three parameters must meet stringent specs simultaneously.

FAQ
What is the operating temperature range of the MAX339MSE/PR3+?
The MAX339MSE/PR3+ is specified for continuous operation from -55°C to +125°C, validated per MIL-STD-883 methods for high-reliability applications. This extended range is achieved through Maxim's 44V silicon-gate process and rigorous screening - making the MAX339MSE/PR3+ suitable for engine-mounted sensors, avionics bays, and space-constrained military electronics where ambient temperatures exceed commercial-grade limits.
Is the MAX339MSE/PR3+ pin-compatible with the DG509A?
Yes, the MAX339MSE/PR3+ is a direct pin-compatible upgrade for the DG509A in the 16-pin Narrow SO package. Pin functions, spacing, and electrical interface match exactly - allowing drop-in replacement without PCB modification. However, the MAX339MSE/PR3+ improves on leakage (<20pA vs. ~100pA), charge injection (1.5pC vs. ~10pC), and ESD tolerance (>2000V vs. unspecified), delivering enhanced performance in the same footprint.
Can the MAX339MSE/PR3+ operate from a single supply?
Yes, the MAX339MSE/PR3+ supports single-supply operation from +4.5V to +30V. In this configuration, connect V− to GND and apply the positive supply to V+. The analog signal range becomes 0V to V+ − 1V (e.g., 0–11V at +12V), maintaining rail-to-rail capability relative to the supply rails. Logic inputs remain TTL/CMOS compatible, and all leakage, resistance, and timing specs are guaranteed across the full -55°C to +125°C range.
What is the maximum allowable voltage difference between V+ and V− for the MAX339MSE/PR3+?
The MAX339MSE/PR3+ has an absolute maximum V+–V− rating of 44V. This limit applies regardless of individual rail values - for example, +24V/V− = -20V is acceptable (44V differential), but +30V/V− = -15V exceeds the 44V limit and risks permanent damage. Operation within ±4.5V to ±20V dual supplies or +4.5V to +30V single supply ensures compliance while preserving guaranteed performance specs for the MAX339MSE/PR3+.
How does the enable (EN) pin function in the MAX339MSE/PR3+?
The EN pin on the MAX339MSE/PR3+ is an active-high digital control that globally enables or disables both 4:1 multiplexer sections. When EN = low (≤0.8V), all analog switches open, presenting high-impedance isolation (>10⁹Ω) between NOx and COMx terminals. When EN = high (≥2.4V), address decoding (A0/A1) determines channel connectivity. EN retains TTL/CMOS compatibility across the full supply and temperature range, enabling direct interfacing with microcontrollers and FPGAs without level-shifting.
