Product details
Overview
The MAX339CSE+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 operating from ±4.5V to ±20V or +4.5V to +30V supplies.
For engineers reviewing the MAX339CSE+T datasheet, MAX339CSE+T pinout, MAX339CSE+T application, or MAX339CSE+T equivalent, this device is evaluated for low-leakage, rail-to-rail analog switching in test equipment, military radios, and sample-and-hold circuits where channel matching (<10Ω), fast transition time (<500ns), and ESD robustness (>2000V) are critical selection criteria.
Technical Context
The MAX339CSE+T implements fully bidirectional CMOS switch architecture with TTL/CMOS-compatible digital inputs (0.8V–2.4V logic thresholds) across its full temperature range (0°C to +70°C). Its internal decode logic supports independent enable-controlled operation of two 4-channel sections (COMA/NO1A–NO4A and COMB/NO1B–NO4B), each with break-before-make timing (10–140ns).
It operates on single or dual supplies using Maxim's 44V silicon-gate process, supporting rail-to-rail analog signal handling (±15V dual, 0–12V single) and guaranteed low off-isolation (–75dB) and crosstalk (–92dB) at 100kHz. Charge injection is tightly controlled (1.5pC typ) to minimize sampling error in precision ADC front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | ≤400Ω max at ±15V dual supply - ensures minimal signal attenuation and gain error in sensor/ADC interfaces |
| NO-Off Leakage | <20pA at +25°C - preserves high-impedance node integrity in low-current measurement paths |
| Charge Injection | 1.5pC typical - reduces voltage glitch and settling time in sample-and-hold applications |
| Transition Time | <500ns - enables multiplexing of signals up to ~1MHz without significant edge distortion |
| On-Resistance Match | <10Ω between channels - maintains consistent gain and linearity across switched signal paths |
| Supply Range | ±4.5V to ±20V dual or +4.5V to +30V single - supports industrial and military power architectures |
| ESD Protection | >2000V per Method 3015.7 - enhances reliability in handling and board-level assembly |
Pinout & Package
MAX339CSE+T is housed in a 16-pin narrow SO package (S16+1, outline 21-0041), RoHS-compliant and lead(Pb)-free, with standard SOIC footprint and 1.27mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 | 2-bit binary address inputs selecting active channel (0–3) for both COMA and COMB sections |
| 2 | V− | Negative supply rail input - must be connected for dual-supply operation or tied to GND for single-supply use |
| 3–6 | NO1A–NO4A | Bidirectional analog inputs for first 4-channel section - support rail-to-rail signal swing |
| 7 | EN | Active-high enable input - disables both sections when low, reducing supply current to ≤150µA |
| 8, 9 | COMA, COMB | Common bidirectional analog outputs - each serves its respective 4-channel group |
| 10–13 | NO1B–NO4B | Bidirectional analog inputs for second 4-channel section - electrically isolated from NO1A–NO4A |
| 14 | V+ | Positive supply rail input - supports up to +30V in single-supply mode |
| 15 | GND | Ground reference for logic and substrate - decoupling required near pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - eliminates level-shifting in ±15V or 0–12V systems |
| TTL/CMOS logic compatibility | 0.8V–2.4V input thresholds over full temp/supply range - simplifies interface with microcontrollers and FPGAs |
| Dual independent 4-channel sections | COMA/NO1A–NO4A and COMB/NO1B–NO4B operate simultaneously - enables parallel signal routing |
| Plug-in upgrade for DG509A | PIN-compatible replacement with lower leakage and charge injection - no PCB redesign needed |
| Low on-resistance match | <10Ω channel-to-channel variation - critical for multi-channel instrumentation requiring matched gain |
Applications
| Test Equipment Signal Routing | Military Radio Channel Selection |
|---|---|

Use Value: Bidirectional conduction and rail-to-rail operation handle AC-coupled voice signals (±3V) and DC loop supervision (–48V); TTL-compatible EN allows centralized control. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG509A | Higher NO-off leakage (50pA vs. <20pA), higher charge injection (5pC vs. 1.5pC), same pinout | Legacy designs requiring drop-in replacement with relaxed leakage specs | Choose DG509A only if existing layout constraints prohibit requalification; MAX339CSE+T offers superior precision performance. |
| MAX329CSE+ | Lower leakage (<5pA) and charge injection (0.5pC), but higher on-resistance (1.2kΩ vs. 400Ω) | Ultra-low-noise instrumentation where signal integrity outweighs insertion loss | Select MAX329CSE+ when sub-picoampere leakage is mandatory; accept higher RON penalty for femtoampere-level measurements. |
Compared with DG509A and MAX329CSE+, the MAX339CSE+T delivers optimal balance of low on-resistance, ultra-low leakage, and industry-standard packaging-making it ideal for mid-precision test and comms systems where both speed and accuracy matter.

FAQ
What supply voltage ranges does the MAX339CSE+T support?
The MAX339CSE+T operates from a single +4.5V to +30V supply or dual ±4.5V to ±20V supplies. When using single supply, V− must be connected to GND. The device maintains specified performance-including ≤400Ω on-resistance and <20pA leakage-across these ranges, with analog signal handling extending rail-to-rail (e.g., 0V to +12V or ±15V).
Is the MAX339CSE+T pin-compatible with the DG509A?
Yes, the MAX339CSE+T is explicitly documented as a pin-compatible upgrade for the DG509A. Both use identical 16-pin narrow SO packaging and share identical pin functions (A0/A1, EN, COMA/COMB, NO1A–NO4A, NO1B–NO4B, V+, V−, GND), enabling direct replacement without PCB modification.
What is the maximum allowable voltage difference between V+ and V− for the MAX339CSE+T?
The absolute maximum voltage difference between V+ and V− is 44V, per Maxim's 44V silicon-gate process specification. This allows asymmetric supplies (e.g., +24V and –5V) as long as their difference remains ≤44V and individual rails stay within ±4.5V to ±20V (dual) or +4.5V to +30V (single) limits.
How does the enable (EN) pin affect power consumption in the MAX339CSE+T?
When EN is low, both 4-channel sections are disabled, reducing total supply current to ≤150µA over temperature. With EN high and all inputs static, I+ is typically 290µA at +25°C. This enable-controlled shutdown enables power gating in battery-operated or thermally constrained systems using the MAX339CSE+T.
Can the MAX339CSE+T be used in sample-and-hold circuits, and why?
Yes, the MAX339CSE+T is well-suited for sample-and-hold circuits due to its 1.5pC typical charge injection-minimizing voltage glitches on the hold capacitor-and <20pA NO-off leakage, which prevents capacitor discharge during hold phase. Its <500ns transition time also supports high-speed sampling up to ~1MHz.
