Product details
Overview
MAX339ESE+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 on-resistance, <20pA NO-off leakage at +25°C, and 1.5pC typical charge injection-enabling precision signal routing in data-acquisition systems and test equipment operating from ±4.5V to ±20V or +4.5V to +30V supplies.
For engineers reviewing the MAX339ESE+T datasheet, MAX339ESE+T pinout, MAX339ESE+T application, or MAX339ESE+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, ESD protection >2000V, and pin compatibility with industry-standard DG509A.
Technical Context
The MAX339ESE+T implements dual independent 4:1 analog multiplexing paths, each controlled by A1/A0 address bits and a shared EN input. Its silicon-gate CMOS architecture supports bidirectional signal flow with matched on-resistance (<10Ω channel-to-channel) and break-before-make switching (10–140ns interval) to prevent transient shorts.
All digital inputs tolerate full supply rails (V− to V+), and internal clamping diodes protect against overvoltage. The device operates across −40°C to +85°C, with leakage currents fully tested at max rated temperature and correlated to +25°C performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | ≤400Ω max at ±15V supplies - ensures minimal signal attenuation and gain error in precision measurement paths |
| NO-Off Leakage | <20pA at +25°C - preserves high-impedance sensor node integrity and reduces offset drift in sample-and-hold circuits |
| Charge Injection | 1.5pC typ - limits voltage glitch on sampled capacitors, critical for 12-bit+ ADC front-ends |
| Transition Time | <500ns - supports multiplexing rates up to ~2MHz in automated test equipment |
| Analog Signal Range | ±15V (dual supply) or 0–12V (single +12V) - enables direct interfacing with industrial sensors and op-amp outputs |
| Supply Range | ±4.5V to ±20V or +4.5V to +30V - accommodates legacy bipolar systems and modern single-supply designs without level-shifting |
| ESD Protection | >2000V per Method 3015.7 - enhances robustness during board handling and system integration |
Pinout & Package
MAX339ESE+T is housed in a 16-pin narrow SOIC (Small Outline Integrated Circuit) package with standard 1.27mm pitch, RoHS-compliant lead finish, and exposed pad omitted (non-EP variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 | 2-bit binary address inputs selecting active channel (00–11) for both mux sections |
| 2 | V− | Negative supply rail connection; referenced to GND in single-supply operation |
| 3–6 | NO1A–NO4A | Bidirectional analog inputs for first 4:1 mux section |
| 7 | EN | Active-high enable controlling conduction state of both mux sections simultaneously |
| 8, 9 | COMA, COMB | Common bidirectional analog outputs - one per 4:1 section |
| 10–13 | NO1B–NO4B | Bidirectional analog inputs for second 4:1 mux section |
| 14 | V+ | Positive supply rail; must be ≥|V−| + 1V for proper operation |
| 15 | GND | Ground reference for logic and substrate; tied to V− in single-supply configurations |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals spanning full V+ to V− range - eliminates need for external level shifters in ±15V systems |
| TTL/CMOS logic compatibility | Inputs accept 0.8V–2.4V thresholds across full temperature and supply ranges - simplifies interface with microcontrollers and FPGAs |
| Plug-in upgrade for DG509A | PIN-TO-PIN compatible with industry-standard DG509A - enables drop-in replacement without PCB redesign |
| Low on-resistance matching | <10Ω max mismatch between channels - maintains amplitude consistency across multiplexed sensor inputs |
| Guaranteed low charge injection | 1.5pC typical - minimizes hold-step error in precision sample-and-hold amplifiers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG509A | Legacy industry-standard pinout; higher on-resistance (600Ω typ), higher charge injection (5pC), no ESD spec | Same footprint but requires layout review for leakage-sensitive designs; not recommended for new designs requiring >12-bit accuracy | Select MAX339ESE+T when upgrading legacy DG509A-based systems needing lower leakage, lower charge injection, or ESD robustness |
| MAX329ESE+ | Lower leakage (<5pA off), lower charge injection (0.5pC), but higher on-resistance (800Ω max) | Better for ultra-high-impedance sensor interfaces (e.g., pH electrodes); unsuitable for low-impedance signal chains requiring <500Ω RON | Choose MAX329ESE+ only if leakage and charge injection dominate design constraints over on-resistance and bandwidth |
Compared with DG509A and MAX329ESE+, the MAX339ESE+T delivers optimal balance of low leakage, low charge injection, and moderate on-resistance-making it the preferred choice for general-purpose precision multiplexing where all three parameters matter.

FAQ
What is the maximum supply voltage range supported by the MAX339ESE+T?
The MAX339ESE+T operates from dual supplies of ±4.5V to ±20V or a single supply of +4.5V to +30V. Absolute maximum ratings specify V+ to V− differential up to 44V, with individual supply pins rated to −0.3V to +44V (V+) and −0.3V to +25V (GND). Exceeding these limits risks permanent damage.
Is the MAX339ESE+T pin-compatible with the DG509A?
Yes, the MAX339ESE+T is explicitly documented as a pin-compatible upgrade for the DG509A. Pin functions, numbering, and package outline match exactly in the 16-pin narrow SOIC configuration, enabling direct replacement without PCB modification.
What is the typical charge injection value for the MAX339ESE+T, and why does it matter?
The MAX339ESE+T has a typical charge injection of 1.5pC, measured with CL = 100pF and RS = 0Ω. This parameter directly impacts voltage step error in sample-and-hold circuits and high-resolution ADC front-ends; lower values reduce settling time and improve DC accuracy after channel switching.
Does the MAX339ESE+T support rail-to-rail analog signal operation?
Yes, the MAX339ESE+T supports rail-to-rail analog signal handling: signals on NO and COM terminals can swing from V− to V+ without distortion or clipping. This capability eliminates level-shifting circuitry when interfacing with op-amps or sensors operating at full supply rails.
What is the guaranteed maximum NO-off leakage current for the MAX339ESE+T at +85°C?
At the maximum operating temperature of +85°C, the MAX339ESE+T guarantees NO-off leakage current of ≤1.65nA (−1.65nA to +1.65nA), as specified in the Electrical Characteristics table for the E-grade (−40°C to +85°C) devices. This value is 100% tested at hot temperature and correlated to +25°C performance.
