Product details
Overview
MAX306EUI+T from Maxim Integrated is a precision 16-channel single-ended CMOS analog multiplexer with ≤100Ω on-resistance, <5Ω channel-to-channel matching, and <10pC charge injection. It operates from ±4.5V to ±20V or +5V to +30V supplies, supports rail-to-rail signal handling up to ±15V, and is rated for -40°C to +85°C industrial temperature range in 28-pin TSSOP package - ideal for test equipment and precision data acquisition systems.
For engineers reviewing the MAX306EUI+T datasheet, MAX306EUI+T pinout, MAX306EUI+T application, or MAX306EUI+T equivalent, key selection criteria include guaranteed on-resistance flatness (≤7Ω), low leakage (<2.5nA NO-off at +85°C), fast switching (<250ns transition time), TTL/CMOS-compatible logic inputs, and plug-in upgrade compatibility with DG406/DG506A.
Technical Context
The MAX306EUI+T implements a monolithic CMOS decoder-driven 1-of-16 switch architecture with integrated level-shifting logic, enabling direct TTL/CMOS input interfacing across its full supply range. Its silicon-gate process ensures matched RON and minimal charge injection critical for sample-and-hold integrity.
All 16 normally-open analog inputs (NO1–NO16) route bidirectionally to a common COM terminal under 4-bit binary address control (A0–A3) and active-high enable (EN). The device guarantees break-before-make timing (≤40ns) and maintains signal fidelity over ±15V analog ranges with <92dB crosstalk suppression at 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V (dual supply) or 0–12V (single +12V supply): enables full-rail signal routing without clipping in precision instrumentation. |
| On-Resistance (RON) | ≤100Ω at +25°C, ≤125Ω over full temperature range: minimizes gain error and voltage drop in sensor front-ends and DAC output paths. |
| RON Matching | <5Ω max between channels: ensures consistent channel gain in multi-sensor scanning systems without per-channel calibration. |
| Charge Injection | <10pC: reduces sampling error in high-impedance sample-and-hold circuits and ADC driver stages. |
| NO Off-Leakage | <2.5nA at +85°C: preserves accuracy in battery-powered, high-impedance measurement nodes over temperature extremes. |
| Transition Time | <250ns: supports multiplexing rates up to ~2MHz in automated test equipment without settling-time penalties. |
| ESD Protection | >2000V HBM: enhances robustness during board assembly and field handling without external protection components. |
Pinout & Package
MAX306EUI+T is housed in a 28-pin Thin Shrink Small Outline Package (TSSOP) with 0.65mm pitch, 4.4mm width, and exposed pad for thermal enhancement. Pin 1 is marked by a dot; pin numbering follows standard counter-clockwise convention from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 27 | V+, V− | Positive/negative supply rails: support bipolar (±4.5V to ±20V) or single-supply (+5V to +30V) operation; V− tied to GND for single-supply use. |
| 12 | GND | Analog/digital reference ground: must be low-impedance connection to minimize noise coupling into sensitive analog paths. |
| 4–11, 19–26 | NO16–NO9, NO1–NO8 | 16 bidirectional analog inputs: each independently selectable to COM; no internal connection on pins 2,3,13 (N.C.). |
| 14–17 | A3–A0 | 4-bit binary address inputs: select one of 16 channels; logic thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) ensure TTL/CMOS compatibility. |
| 18 | EN | Active-high enable: disables all switches when low; allows power-gating and system-level channel arbitration. |
| 28 | COM | Common bidirectional analog output: connects selected NOx channel; handles rail-to-rail signals up to ±15V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs spanning full supply rails (±15V dual / 0–12V single), eliminating level-shifting circuitry in mixed-signal interfaces. |
| Guaranteed RON flatness | ≤7Ω variation across ±10V signal range ensures stable gain and minimal THD in audio and sensor signal chains. |
| Low power consumption | <1.25mW typical quiescent power enables integration into portable and battery-operated instrumentation without thermal derating. |
| Plug-in upgrade path | Pin- and function-compatible replacement for industry-standard DG406 and DG506A, simplifying legacy design refreshes. |
| TTL/CMOS logic compatibility | Direct interface with microcontrollers and FPGAs without level translators, reducing BOM count and layout complexity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | 8-channel, not 16-channel; RON = 100Ω typ but no guaranteed matching spec; −40°C to +85°C, 28-TSSOP. | Suitable only where channel count reduction is acceptable; lacks RON matching guarantee needed for precision gain-matched arrays. | Select ADG408BRUZ only if 8-channel capacity suffices and channel-to-channel matching is non-critical. |
| TMUX1308PWR | 8-channel, single-supply only (1.8–5.5V); RON = 4.5Ω typ but limited voltage range; −40°C to +125°C, 16-TSSOP. | Not viable for ±15V or high-voltage signal routing; incompatible with bipolar supply architectures used in industrial test gear. | Choose TMUX1308PWR only for low-voltage, space-constrained, single-supply designs where high-voltage capability is unnecessary. |
Compared with ADG408BRUZ and TMUX1308PWR, the MAX306EUI+T uniquely delivers 16-channel count, guaranteed RON matching, ±15V signal handling, and bipolar supply flexibility - making it irreplaceable in high-precision, multi-sensor industrial and military systems.

FAQ
What supply voltage ranges does the MAX306EUI+T support?
The MAX306EUI+T operates from ±4.5V to ±20V bipolar supplies or +5V to +30V single supply. When using single supply, V− must be connected to GND. The device maintains specified performance across this full range, including rail-to-rail analog signal handling up to ±15V (dual) or 0–12V (single +12V), as confirmed in the Electrical Characteristics tables.
Is the MAX306EUI+T pin-compatible with the DG406 or DG506A?
Yes, the MAX306EUI+T is explicitly designed as a plug-in upgrade for the DG406 and DG506A, with identical pinout, function, and package footprint in 28-pin TSSOP. This enables direct replacement without PCB modification, preserving existing layouts while delivering improved specs: lower RON, tighter matching, reduced charge injection, and enhanced ESD protection.
What is the maximum allowable analog signal voltage for the MAX306EUI+T?
The MAX306EUI+T supports analog signals from V− − 2V to V+ + 2V, with absolute maximum ratings of −0.3V to +44V on NO/COM pins relative to V−. Under normal operation with ±15V supplies, the usable analog range is ±15V; with +12V single supply (V− = GND), it is 0–12V. These limits are guaranteed in the datasheet's Absolute Maximum Ratings and Electrical Characteristics sections.
How does the MAX306EUI+T handle channel switching timing?
The MAX306EUI+T guarantees break-before-make timing of ≤40ns and transition time <250ns (typ 110ns) under ±15V supplies. Enable turn-on/off times are ≤200ns/150ns respectively. These values ensure minimal signal disruption during channel changes and support multiplexing frequencies up to ~2MHz in time-critical applications like automated test equipment and real-time data acquisition.
Does the MAX306EUI+T require external decoupling capacitors?
Yes, the MAX306EUI+T requires local 0.1µF ceramic decoupling capacitors between V+ and GND, and between V− and GND, placed as close as possible to the respective pins. This is mandated in the Applications Information section to suppress supply transients and maintain low-noise analog performance - especially critical given its low-leakage, high-precision target applications.
