Product details
Overview
The MAX396CAI+ 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, ≤6Ω channel-to-channel RON matching, <1nA input off-leakage at +85°C, and operates from +2.7V to +16V single supply or ±2.7V to ±8V dual supplies.
For engineers reviewing the MAX396CAI+ datasheet, MAX396CAI+ pinout, MAX396CAI+ application, or MAX396CAI+ equivalent, this device supports high-accuracy analog switching in battery-powered instrumentation, automated test equipment, and industrial process control where low charge injection (≤5pC) and flat on-resistance over signal range are critical.
Technical Context
The MAX396CAI+ implements a silicon-gate CMOS architecture with integrated address decoding (A0–A3) and enable control (EN), selecting one of 16 bidirectional analog inputs (NO1–NO16) to the common output (COM). Its switch design guarantees break-before-make operation and maintains RON flatness ≤10Ω across ±3.5V signal range under dual-supply conditions.
It features guaranteed electrostatic discharge protection >2000V (HBM), TTL/CMOS-compatible logic inputs (VAL ≤0.8V, VAH ≥2.4V), and supports unbalanced supplies (e.g., +10V/−5V). Transition time is <250ns, and charge injection is limited to 5pC max-critical for sample-and-hold and precision ADC front-end applications.

Pinout & Package
MAX396CAI+ is housed in a 28-pin shrink small-outline package (SSOP) with 0.635mm pitch, footprint-compatible with industry-standard 28-pin SO and PLCC variants. The package supports surface-mount reflow assembly and provides thermal performance suitable for industrial ambient temperatures.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG406DN | Higher typical on-resistance (120Ω), no guaranteed RON matching spec, 1500V HBM ESD rating | Suitable for general-purpose routing but not precision ratiometric or low-leakage designs | Select DG406DN only when cost sensitivity outweighs need for ≤6Ω matching and <1nA leakage at +85°C |
| MAX306EPI+ | Same pinout and function; slightly higher RON (125Ω max), wider temp range (−40°C to +85°C), DIP package | Drop-in replacement for legacy through-hole designs requiring extended temperature operation | Choose MAX306EPI+ for through-hole prototyping or systems requiring −40°C startup capability |
Compared with DG406DN and MAX306EPI+, the MAX396CAI+ offers superior RON matching and lower leakage-critical for high-resolution data acquisition-while MAX306EPI+ provides broader temperature support in a through-hole format, and DG406DN trades performance for cost in non-critical signal paths.

FAQ
What is the maximum analog signal range supported by the MAX396CAI+?
The MAX396CAI+ supports an analog signal range from V− to V+, meaning it can pass signals spanning the full supply rails. With ±5V dual supplies, that is ±5V; with +5V single supply (V− = GND), the range is 0V to +5V. Absolute maximum ratings allow V− to −17V and V+ to +17V, but operational range is constrained by supply configuration. The MAX396CAI+ maintains specified RON flatness up to ±3.5V under dual-supply conditions.
Is the MAX396CAI+ pin-compatible with the MAX306 series?
Yes, the MAX396CAI+ is explicitly pin-compatible with the MAX306/MAX307, DG406/DG407, and DG506A/DG507A families. Pin assignments-including COM, NO1–NO16, A0–A3, EN, V+, V−, and GND-are identical across these devices. This allows direct substitution in existing layouts without PCB modification, provided supply and signal requirements align with the MAX396CAI+'s specifications.
What is the guaranteed on-resistance matching between channels for the MAX396CAI+?
The MAX396CAI+ guarantees on-resistance matching of ≤6Ω between any two channels at +25°C, and ≤8Ω over the full operating temperature range (0°C to +70°C for the 'C' grade). This specification-defined as ΔRON = RON(MAX) − RON(MIN)-ensures consistent gain scaling and minimal channel-to-channel error in multiplexed measurement systems using the MAX396CAI+.
Does the MAX396CAI+ support single-supply operation below +2.7V?
No-the MAX396CAI+ is not guaranteed to operate below +2.7V. While the device may function down to ~1V, on-resistance increases significantly and switching times degrade beyond specification. Performance parameters-including RON, leakage, and transition time-are only assured within the rated supply range of +2.7V to +16V (single supply) or ±2.7V to ±8V (dual supply). Operating the MAX396CAI+ outside this range risks parametric noncompliance.
How does the enable (EN) pin affect leakage and power in the MAX396CAI+?
When the EN pin is logic low, all internal switches are disabled, reducing total supply current to <1µA and minimizing off-state leakage (NO and COM off-leakage remains <1nA at +85°C). This state effectively isolates all channels and cuts dynamic power, making the MAX396CAI+ suitable for power-gated subsystems. Asserting EN high activates the selected channel while maintaining the specified leakage and RON performance.
