Product details
Overview
MAX339ESE 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 supplies.
For engineers reviewing the MAX339ESE datasheet, MAX339ESE pinout, MAX339ESE application, or MAX339ESE equivalent, this page delivers verified specifications, package-validated pin functions, real-world application contexts, and two confirmed alternative parts with documented technical and application differences for reliable selection in low-leakage, rail-to-rail analog switching designs.
Technical Context
The MAX339ESE implements fully bidirectional analog switching using silicon-gate CMOS process technology, supporting both single-supply (+4.5V to +30V) and bipolar-supply (±4.5V to ±20V) operation with TTL/CMOS-compatible digital inputs. Its internal decode logic accepts A0/A1 address bits and an active-high EN signal to select one of four channels per COM output.
Each channel exhibits matched on-resistance (≤10Ω max mismatch), guaranteed low charge injection (1.5pC typ), and ESD protection >2000V (Method 3015.7). Signal handling extends rail-to-rail-VCOM and VNO swing from V− to V+-with off-isolation of −75dB and crosstalk of −92dB at 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | ≤400Ω max at ±15V - ensures minimal voltage drop and gain error in precision sensor or DAC/ADC interface paths |
| NO-Off Leakage | <20pA at +25°C - preserves high-impedance node integrity in sample-and-hold and high-resolution measurement circuits |
| Charge Injection | 1.5pC typical - limits settling error and droop in fast-switching, capacitor-coupled signal chains |
| Transition Time | <500ns - supports multiplexing of signals up to ~1MHz without significant edge distortion |
| Supply Range | ±4.5V to ±20V dual or +4.5V to +30V single - enables direct interfacing with industrial ±15V and automotive 12V/24V rails |
| ESD Protection | >2000V per Method 3015.7 - reduces need for external protection in field-deployable test and military radio systems |
| Off Isolation | −75dB at 100kHz - prevents signal coupling between inactive channels in multi-sensor monitoring applications |
Pinout & Package
MAX339ESE is supplied in a 16-pin narrow SO (Small Outline) package with standard 1.27mm pitch and RoHS-compliant lead finish. The package is thermally optimized for surface-mount assembly and provides full electrical access to all control and analog terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 Address Inputs | Binary-select lines determining active channel (00–11); TTL/CMOS compatible across full supply and temperature range |
| 2 | EN Enable Input | Active-high logic control enabling/disabling both 4-channel sections simultaneously; disables all switches when low |
| 3 | V− | Negative supply rail connection; required for bipolar operation or referenced single-supply configurations |
| 4–7 | NO1A–NO4A | Analog inputs for Section A; bidirectional, rail-to-rail capable, with ≤400Ω on-resistance and ≤20pA off-leakage |
| 8, 9 | COMA, COMB | Common analog outputs for Sections A and B; serve as input or output depending on signal flow direction |
| 10–13 | NO4B–NO1B | Analog inputs for Section B; electrically identical to NO1A–NO4A with matched RON and leakage performance |
| 14 | V+ | Positive supply rail; must be ≥|V−| + 4.5V in dual-supply mode; connects to exposed pad in TQFN variants (not applicable to SO) |
| 15 | GND | Digital ground reference; decoupling recommended near pin for noise-sensitive analog routing |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | VNO/VCOM operate from V− to V+, enabling full dynamic range use in ±15V instrumentation and 0–12V industrial control |
| Low on-resistance match | ≤10Ω max channel-to-channel RON variation - minimizes gain error when multiplexing matched sensor bridges or calibration references |
| TTL/CMOS logic compatibility | Input thresholds fixed at +0.8V (low) and +2.4V (high) across −40°C to +85°C - eliminates level-shifting in mixed-voltage microcontroller interfaces |
| Plug-in upgrade for DG509A | PIN-compatible replacement for industry-standard dual 4-channel mux - allows drop-in redesign without PCB changes in legacy test equipment |
| Bidirectional conduction | Identical RON, leakage, and capacitance in either direction - supports analog signal routing and feedback path switching in programmable gain amplifiers |

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 |
|---|---|---|---|
| MAX329ESE+ | Lower NO-off leakage (5pA typ vs. 20pA) and charge injection (0.5pC typ), but higher on-resistance (1.2kΩ max vs. 400Ω) | Better suited for ultra-high-impedance pH sensors or photodiode transimpedance amplifier multiplexing where leakage dominates error budget | Select MAX329ESE+ only when leakage <10pA is mandatory and RON >1kΩ is acceptable; avoid in precision gain-setting or low-source-impedance paths. |
| DG509AEY+ | Industry-standard pinout and function, but higher on-resistance (600Ω max), higher charge injection (5pC typ), and no guaranteed ESD rating | Legacy drop-in replacement where existing layout uses DG509A footprint and modern ESD robustness is not required | Choose DG509AEY+ only for cost-sensitive, non-ruggedized commercial test fixtures; MAX339ESE offers superior leakage, speed, and reliability for new designs. |
Compared with MAX329ESE+ and DG509AEY+, the MAX339ESE delivers optimal balance of low leakage, low RON, fast switching, and rugged ESD protection-making it the preferred choice for new industrial, military, and test-equipment designs requiring verified performance across temperature and supply extremes.

FAQ
What is the maximum allowable supply voltage difference for MAX339ESE?
The MAX339ESE specifies an absolute maximum V+–V− differential of 44V. Operation within the recommended dual-supply range of ±4.5V to ±20V (i.e., 9V to 40V total span) ensures full parametric compliance. Exceeding 44V risks permanent damage, even if individual rails remain within ratings. Always observe proper power sequencing: V+ first, then V−, then logic inputs.
Does MAX339ESE support single-supply operation, and how is V− handled?
Yes, MAX339ESE operates from a single +4.5V to +30V supply. In this configuration, connect V− to circuit ground (GND). The device maintains rail-to-rail analog signal capability from 0V to V+, with verified performance at +12V and +15V. All digital inputs remain TTL/CMOS-compatible, and leakage/switching specs hold across the full temperature range.
Is MAX339ESE pin-compatible with the DG509A, and what design changes are needed?
Yes, MAX339ESE is a pin-compatible, functionally identical upgrade for the DG509A in 16-pin narrow SO packages. No PCB layout changes are required. Key improvements include guaranteed ≤400Ω on-resistance (vs. 600Ω max for DG509A), 1.5pC charge injection (vs. 5pC), and >2000V ESD protection-delivering enhanced accuracy and field reliability without redesign effort.
What is the guaranteed on-resistance matching specification for MAX339ESE across temperature?
MAX339ESE guarantees on-resistance matching (ΔRON = RON(MAX) – RON(MIN)) of ≤15Ω over the full −40°C to +85°C operating range, and ≤10Ω at +25°C. This tight matching ensures consistent gain and offset across channels in applications like programmable-gain instrumentation amplifiers or multi-sensor calibration banks.
Can MAX339ESE be used in bidirectional signal paths, and what parameters confirm this capability?
Yes, MAX339ESE is fully bidirectional: its on-resistance, leakage currents, capacitance, and charge injection are symmetric for signal flow from NO to COM or COM to NO. Confirmed by datasheet specs showing identical RON, INO(OFF), ICOM(OFF), and Q values regardless of direction-enabling flexible use in feedback networks, transducer excitation, and analog bus architectures.
