Product details
Overview
MAX396EWI+T from Maxim Integrated is a precision 16-channel single-ended analog multiplexer IC designed for low-voltage signal routing in data acquisition and test systems. It delivers ≤100Ω on-resistance (max), ≤6Ω channel-to-channel RON matching, and <1nA input off-leakage at +85°C, operating from +2.7V to +16V single supply or ±2.7V to ±8V dual supplies.
For engineers reviewing the MAX396EWI+T datasheet, MAX396EWI+T pinout, MAX396EWI+T application, or MAX396EWI+T equivalent, this device supports high-accuracy analog switching in battery-powered instrumentation, industrial process control, and automated test equipment where low charge injection (≤5pC) and flat on-resistance over signal range are critical.
Technical Context
The MAX396EWI+T implements a CMOS silicon-gate architecture with break-before-make switching, enabling precise channel isolation during address transitions. Its digital control interface accepts TTL/CMOS-compatible logic levels (VAL ≤ 0.8V, VAH ≥ 2.4V) across all temperature ranges and supports 4-bit binary address decoding (A0–A3) plus enable (EN) for channel selection.
It features internal ESD protection >2000V (per Method 3015.7) and operates across –40°C to +85°C. The device maintains guaranteed RON flatness ≤10Ω over its full analog signal range (V– to V+), ensuring minimal gain error in precision measurement paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 16-channel single-ended analog multiplexer - routes one of 16 inputs to common output (COM) |
| On-resistance (RON) | ≤100Ω max at +25°C (V± = ±5V); ensures minimal voltage drop and signal attenuation in sensor/ADC front-ends |
| RON matching | ≤6Ω max between channels - enables consistent gain scaling across multi-channel systems without per-channel calibration |
| Charge injection | ≤5pC max - minimizes voltage glitch on sampled-hold capacitors, critical for high-resolution ADC interfaces |
| Input off-leakage | <1nA at +85°C - preserves accuracy in high-impedance sensor circuits (e.g., thermocouples, pH electrodes) |
| Supply range | +2.7V to +16V single supply or ±2.7V to ±8V dual supply - supports wide-range industrial and portable designs |
| Transition time | <250ns max - enables fast multiplexing in real-time data acquisition up to ~1MHz effective sampling rate |
Pinout & Package
MAX396EWI+T is housed in a 28-pin Wide SO (Small Outline) package with 300 mil body width, RoHS-compliant and lead-free. Pin pitch is 0.050", and thermal pad is not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply voltage input | Accepts +2.7V to +16V; substrate tied internally to V+ for latch-up immunity |
| V− | Negative supply voltage input | Accepts −16V to −2.7V in dual-supply mode; must be connected to GND in single-supply operation |
| GND | Logic ground reference | Reference for digital inputs (A0–A3, EN); separate from analog signal ground path |
| COM | Analog common output terminal | Bidirectional node connecting selected NOx channel; must be routed with low-noise layout practices |
| NO1–NO16 | Analog input terminals | 16 bidirectional analog signal pins; each electrically identical and interchangeable with COM |
| A0–A3 | Binary address inputs | 4-bit code selects active channel (0–15); latched on rising edge of EN when enabled |
| EN | Active-high enable input | High = channel switching enabled; low = all switches open (high-Z state), reducing system power leakage |
| N.C. | No internal connection | Pins 2, 3, 13 - left unconnected; no internal circuitry attached; may be floated or grounded per layout needs |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility | Fully pin-compatible with industry-standard MAX306, DG406, and DG506A - enables drop-in replacement without PCB redesign |
| RON flatness | ≤10Ω variation over full signal range (V− to V+) - eliminates amplitude distortion in AC-coupled or rail-to-rail signal paths |
| Low power consumption | <10μW typical quiescent power - extends battery life in portable DMMs and handheld analyzers |
| ESD robustness | >2000V HBM - reduces field failure risk in manufacturing handling and end-equipment integration |
| Off-isolation | −75dB at 100kHz - suppresses crosstalk between inactive channels in dense multi-signal environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX306EWI+T | Same 16-channel architecture but higher RON (120Ω max) and wider RON matching (15Ω max); no guaranteed RON flatness spec | Suitable for less demanding DC-coupled applications where cost is prioritized over precision matching | Select MAX306EWI+T only if RON matching >6Ω and flatness >10Ω are acceptable in your signal chain |
| DG406DN-E3 | 16-channel mux with 100Ω RON (max), but higher charge injection (15pC) and no guaranteed <1nA leakage at +85°C | Better suited for general-purpose switching where ultra-low leakage or precision matching is not required | Prefer DG406DN-E3 for cost-sensitive industrial controls where leakage and charge injection specs are relaxed |
Compared with MAX396EWI+T, MAX306EWI+T trades precision RON performance for legacy compatibility, while DG406DN-E3 offers broader availability but lacks guaranteed high-temperature leakage and flatness-making MAX396EWI+T optimal for metrology-grade signal routing.

FAQ
What is the operating temperature range for MAX396EWI+T?
The MAX396EWI+T is rated for operation from –40°C to +85°C, meeting the extended industrial temperature grade (E-grade). This range is validated across all key parameters including on-resistance, leakage current, and switching speed, making it suitable for deployment in harsh environments such as factory automation and outdoor instrumentation where thermal stability is critical. The MAX396EWI+T maintains guaranteed performance within these limits without derating.
Does MAX396EWI+T support single-supply operation?
Yes, MAX396EWI+T supports single-supply operation from +2.7V to +16V. In this configuration, V− must be connected to GND, and the analog signal range becomes 0V to V+. The device retains full TTL/CMOS logic compatibility and specified performance-including ≤100Ω RON and <1nA off-leakage-at +25°C and across the full temperature range. Performance remains guaranteed down to +2.7V; operation below this voltage is not characterized.
What is the maximum analog signal range supported by MAX396EWI+T?
The MAX396EWI+T supports an analog signal range from V− to V+, meaning it can pass signals spanning the full supply rails. With ±5V dual supplies, this equals –5V to +5V; with +5V single supply (V− = GND), it is 0V to +5V. This rail-to-rail capability is guaranteed by design and maintained across temperature, enabling direct interfacing with op-amps, sensors, and ADCs without level-shifting circuitry. The MAX396EWI+T does not require external clamping diodes for signals within this range.
Is MAX396EWI+T pin-compatible with other industry-standard multiplexers?
Yes, MAX396EWI+T is explicitly pin-compatible with MAX306, DG406, and DG506A devices in the same 28-pin Wide SO package. This includes identical pin assignments for V+, V−, GND, COM, NO1–NO16, A0–A3, EN, and N.C. terminals. No PCB layout changes are required for migration, and the MAX396EWI+T provides superior specifications-including tighter RON matching and lower leakage-while maintaining functional and mechanical interchangeability.
How does charge injection affect system performance with MAX396EWI+T?
MAX396EWI+T guarantees ≤5pC maximum charge injection, which directly determines the voltage glitch induced on downstream hold capacitors. For example, with a 100pF sampling capacitor, ≤5pC translates to ≤50mV step error-critical for 12-bit+ resolution systems. This low value minimizes settling time and avoids re-sampling delays in successive-approximation ADC architectures. The MAX396EWI+T achieves this via optimized transistor sizing and layout, verified across temperature and supply conditions.
