Product details
Overview
The MAX339CPE+ 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 operating from ±4.5V to ±20V or +4.5V to +30V supplies.
For engineers reviewing the MAX339CPE+ datasheet, MAX339CPE+ pinout, MAX339CPE+ application, or MAX339CPE+ 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 for drop-in upgrades in test equipment and military radios.
Technical Context
The MAX339CPE+ implements fully bidirectional CMOS switch architecture with independent decode logic for two 4-channel sections (COMA/NO1A–NO4A and COMB/NO1B–NO4B), each controlled by shared A0/A1 address lines and a common EN input. Its 44V silicon-gate process enables operation over ±4.5V to ±20V dual supplies or +4.5V to +30V single supply (V− tied to GND).
All digital inputs-including EN, A0, and A1-are TTL-compatible (+0.8V to +2.4V) across the full 0°C to +70°C operating range and ±4.5V to ±18V supply window. Break-before-make switching (10–140ns) and low crosstalk (−92dB at 100kHz) ensure channel isolation during state transitions without signal coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | ≤400Ω max at ±15V, enabling ≤2mV error at 5mA signal current |
| NO-Off Leakage | <20pA at +25°C, critical for high-impedance sensor front-ends |
| Charge Injection | 1.5pC typ, limiting voltage glitch to <15mV on 100pF hold capacitor |
| Transition Time | <500ns, supporting multiplexing rates up to 2MHz in DAQ systems |
| Analog Signal Range | ±15V (dual supply), supporting rail-to-rail input/output swing |
| Supply Range | +4.5V to +30V single or ±4.5V to ±20V dual-no level-shifting needed |

Pinout & Package
The MAX339CPE+ is housed in a 16-pin plastic DIP (PDIP) package with 0.3-inch width, RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 | 2-bit binary address inputs selecting active channel (00–11) per section |
| 2 | EN | Active-high enable: disables all switches when low, prevents signal contention |
| 3 | V− | Negative supply rail; must be ≥−20V and ≤V+ − 44V |
| 4–7 | NO1A–NO4A | Bidirectional analog inputs for first 4-channel section |
| 8, 9 | COMA, COMB | Common bidirectional outputs-one per 4-channel section |
| 10–13 | NO4B–NO1B | Bidirectional analog inputs for second 4-channel section (reversed order) |
| 14 | V+ | Positive supply rail; must be ≤+30V and ≥V− + 44V |
| 15 | GND | Digital ground reference; decoupling required near V+/V− pins |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping-no external biasing needed |
| TTL/CMOS logic compatibility | Direct interface to microcontrollers and FPGAs without level shifters across full temp/supply range |
| Plug-in upgrade for DG509A | PIN-TO-PIN compatible with identical pinout and function-no PCB change required |

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 part; higher on-resistance (600Ω max), higher charge injection (5pC), no ESD spec | Same pinout but lacks guaranteed low-leakage performance at temperature extremes | Select DG509A only for cost-sensitive legacy repairs where MAX339CPE+ qualification is not required |
| MAX329CPE+ | Lower leakage (<5pA off, <10pA on) and lower charge injection (0.5pC), but higher RON (1kΩ max) | Better for ultra-high-Z sensor interfaces; unsuitable for low-impedance audio or power-sensing paths | Choose MAX329CPE+ when leakage dominates error budget and signal current is <1mA |
Compared with DG509A and MAX329CPE+, the MAX339CPE+ delivers optimal balance of low leakage, low RON, and robust ESD protection-making it preferred for new designs requiring reliability across industrial and military temperature ranges without sacrificing speed or signal fidelity.

FAQ
What is the maximum supply voltage range supported by the MAX339CPE+?
The MAX339CPE+ operates from a single +4.5V to +30V supply or dual supplies of ±4.5V to ±20V. The absolute maximum differential voltage between V+ and V− is 44V. Exceeding these limits risks permanent damage, as specified in the Absolute Maximum Ratings table.
Is the MAX339CPE+ pin-compatible with the DG509A?
Yes, the MAX339CPE+ is a pin-compatible upgrade for the DG509A. Both use identical 16-pin PDIP packaging and share identical pin functions-including A0/A1 address inputs, EN enable, COMA/COMB outputs, and NOxA/NOxB inputs-allowing direct replacement without PCB modification.
What is the typical charge injection value for the MAX339CPE+, and why does it matter?
The MAX339CPE+ has a typical charge injection of 1.5pC, measured with CL = 100pF and RS = 0Ω. This low value minimizes voltage glitches on hold capacitors in sample-and-hold circuits, directly improving DC accuracy and settling time in precision data-acquisition systems.
Can the MAX339CPE+ operate with unbalanced supplies like +24V and −5V?
Yes, the MAX339CPE+ supports unbalanced supplies such as +24V and −5V, provided the difference between V+ and V− does not exceed 44V and both rails remain within their absolute maximum ratings (V+ ≤ +30V, V− ≥ −20V). This flexibility simplifies power architecture in mixed-signal systems.
What is the guaranteed NO-off leakage current for the MAX339CPE+ at +70°C?
At the maximum operating temperature of +70°C, the MAX339CPE+ guarantees NO-off leakage current of ≤1.25nA (−1.25nA to +1.25nA), as specified in the Electrical Characteristics table for the C-grade temperature range. This ensures minimal signal corruption in high-impedance multiplexed sensor networks.
