Product details
Overview
MAX396C/D from Maxim Integrated is a precision 16-channel single-ended CMOS analog multiplexer 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 <5pC charge injection - enabling high-fidelity switching in ±2.7V to ±8V or +2.7V to +16V supply configurations. Its operation supports battery-powered instrumentation and industrial process control where leakage (<1nA at +85°C) and flat RON over signal range are critical.
For engineers reviewing the MAX396C/D datasheet, MAX396C/D pinout, MAX396C/D application, or MAX396C/D equivalent, this page provides verified electrical specifications, functional pin mapping, real-world use cases in low-leakage signal routing, and validated alternative parts with documented differences in channel count, supply range, and thermal performance.
Technical Context
The MAX396C/D implements a silicon-gate CMOS architecture optimized for precision analog switching, featuring break-before-make timing (≤70ns), TTL/CMOS-compatible digital inputs, and guaranteed electrostatic discharge protection >2000V. Its internal decoder drives 16 bidirectional analog switches using four address lines (A0–A3) and an active-high enable (EN).
It operates across three supply configurations: dual-symmetric (±2.7V to ±8V), dual-asymmetric (e.g., +10V/−5V), or single-ended (+2.7V to +16V), with analog signal range extending from V− to V+. All channels share identical RON flatness (≤10Ω max) and leakage behavior, ensuring consistent channel performance without calibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 16 single-ended analog switches - enables dense signal routing in multichannel DAQ and ATE without external decoding logic. |
| On-resistance (RON) | ≤100Ω max at +25°C (dual ±5V); ensures minimal signal attenuation and gain error in precision sensor interfaces. |
| RON matching | ≤6Ω max between channels - guarantees matched gain/attenuation across multiplexed sensor or calibration paths. |
| Charge injection | ≤5pC max - limits voltage glitch on sampled nodes, critical for high-resolution SAR ADC front-ends. |
| Off-leakage current | <1nA at +85°C (NO/COM) - preserves accuracy in high-impedance pH, thermocouple, or piezoelectric sensor circuits. |
| Supply range | +2.7V to +16V single or ±2.7V to ±8V dual - supports direct integration with Li-ion, 5V, and ±5V legacy systems. |
| Transition time | <250ns max - allows sampling rates up to ~1MHz in time-multiplexed measurement architectures. |
Pinout & Package
Dice form factor (no package); bare die intended for hybrid module or custom substrate integration. Bond pad layout matches 28-pin PLCC footprint per Maxim's chip topography documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| COM | Analog common output | Bidirectional node connecting to all 16 NOx channels; must be routed with controlled impedance in high-frequency applications. |
| NO1–NO16 | Analog input/output terminals | 16 fully interchangeable analog ports; each exhibits identical RON, leakage, and capacitance specs when selected. |
| A0–A3 | Binary address inputs | 4-bit code selects one of 16 channels; logic thresholds (VAL ≤0.8V, VAH ≥2.4V) ensure compatibility with 3.3V/5V microcontrollers. |
| EN | Active-high enable | Disables all switches when low; prevents signal coupling during power-up/down or standby modes. |
| V+, V− | Supply rails | Supports rail-to-rail analog signal swing; V− tied to GND for single-supply operation. |
| GND | Logic reference | Separate from analog ground in mixed-signal layouts; requires low-impedance connection to minimize digital noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility | Fully pin-compatible with MAX306, DG406, and DG506A - enables drop-in replacement in existing PCBs without layout changes. |
| RON flatness | ≤10Ω variation over full analog signal range (V− to V+) - eliminates gain nonlinearity in DC-coupled sensor multiplexing. |
| ESD robustness | >2000V HBM - reduces field failure risk in handling and automated assembly of test equipment modules. |
| Low power consumption | <10μW quiescent - extends battery life in portable multimeters and handheld analyzers. |
| Temperature stability | RON drift <125Ω max over −40°C to +85°C - maintains calibration integrity in uncontrolled industrial environments. |
Applications
| Automatic Test Equipment | Industrial Process Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX306CPI | Same 16-channel function, but rated only to +70°C (vs. MAX396C/D's dice-level spec); higher RON (120Ω typ) and leakage (5nA at +85°C). | Less suitable for extended-temperature industrial deployments; acceptable for lab-grade bench instruments. | Select MAX306CPI only if cost sensitivity outweighs leakage and temperature requirements. |
| DG406DN | 16-channel, but requires minimum ±5V supplies; no single-supply support; RON flatness not specified; 10pC charge injection (2× higher). | Not viable for battery-powered or low-voltage embedded systems; limited to fixed-rail industrial controllers. | Choose DG406DN only when legacy ±5V infrastructure exists and charge injection is noncritical. |
Compared with MAX306CPI and DG406DN, the MAX396C/D offers superior leakage performance, wider supply flexibility, and tighter RON matching - making it the preferred choice for precision, low-power, and extended-temperature analog multiplexing where signal fidelity is non-negotiable.

FAQ
What is the maximum supply voltage rating for MAX396C/D?
The MAX396C/D supports a single positive supply up to +16V or dual supplies from ±2.7V to ±8V. Absolute maximum ratings specify V+ to V− differential up to 17V and individual rail limits of −0.3V to +17V (V+) and +0.3V to −17V (V−). Operation beyond these stresses risks permanent damage, and performance is not guaranteed below +2.7V.
Does MAX396C/D support single-supply operation at 3.3V?
Yes, the MAX396C/D operates with a single +3.3V supply. At this voltage, typical on-resistance rises to ~315Ω (at +25°C), transition time increases to ~230ns, and analog signal range narrows to 0V to +3.3V. Performance remains fully functional and specified - confirmed in the "Single +3V Supply" section of the datasheet.
What is the purpose of the EN pin on MAX396C/D?
The EN (Enable) pin on MAX396C/D is an active-high digital control that globally enables or disables all 16 analog switches. When EN is low, all channels are open-circuited regardless of address inputs; when high, channel selection proceeds via A0–A3. This allows synchronized switching across all paths and safe power sequencing during system startup.
How does MAX396C/D handle overvoltage conditions on analog inputs?
The MAX396C/D includes internal ESD protection diodes clamping analog pins to V+ and V−. If input voltage exceeds V+ or falls below V−, forward current must be limited to ±30mA continuous (±50mA peak) to prevent damage. External series resistors are recommended for sustained overvoltage exposure, especially in field-connected sensor interfaces.
Is MAX396C/D pin-compatible with MAX306 in all package variants?
Yes - the MAX396C/D die is functionally and pinout-identical to the packaged MAX306 family (e.g., MAX306CPI, MAX306EWI). Pin assignments for COM, NO1–NO16, A0–A3, EN, V+, V−, and GND match exactly, enabling direct substitution in existing layouts when migrating from packaged to bare-die integration.
