Product details
Overview
MAX307MWI/PR from Maxim Integrated is a precision differential 2-of-8 CMOS analog multiplexer designed for high-fidelity signal routing in demanding environments. It features <100Ω on-resistance, <5Ω channel-to-channel matching, <10pC charge injection, <2.5nA NO off-leakage at +85°C, and operates across ±4.5V to ±20V or +5V to +30V supplies - enabling use in military-grade guidance systems and battery-operated test equipment.
For engineers reviewing the MAX307MWI/PR datasheet, MAX307MWI/PR pinout, MAX307MWI/PR application, or MAX307MWI/PR equivalent, key selection considerations include guaranteed on-resistance flatness (≤7Ω), rail-to-rail analog signal handling (±15V dual supply), ESD protection >2000V, TTL/CMOS logic compatibility, and -55°C to +125°C extended temperature operation in 28-pin Wide SO package.
Technical Context
The MAX307MWI/PR implements a differential 2-of-8 switching architecture with independent COMA and COMB outputs, controlled by three address lines (A0–A2) and an active-high enable (EN). Its silicon-gate CMOS process ensures matched switch characteristics and low leakage across the full industrial temperature range.
It supports unbalanced supplies (e.g., +24V/–5V), maintains rail-to-rail signal integrity, and guarantees break-before-make timing (10–40ns) to prevent signal shorting during channel transitions - critical for sample-and-hold and precision instrumentation applications.
Key Specifications

|---|---|
| Analog Signal Range | ±15V (dual supply); enables full-rail signal routing without clipping in ±15V systems |
| On-Resistance (RON) | <100Ω max at +25°C; ensures minimal voltage drop and gain error in precision signal paths |
| On-Resistance Matching | <5Ω max between channels; preserves amplitude accuracy when switching between differential pairs |
| Charge Injection | <10pC; reduces settling error and droop in sample-and-hold and ADC front-end circuits |

Pinout & Package
MAX307MWI/PR is housed in a 28-pin Wide SO (SOIC-W) package with gull-wing leads, RoHS-compliant, and rated for -55°C to +125°C operation. The package footprint matches industry-standard 28-Wide SO land pattern 90-0109.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, V+ | Positive supply voltage input | Accepts +5V to +30V (single) or up to +20V (bipolar); powers internal logic and switch array |
| 2, COMB | Differential output B | Bidirectional path for second channel of differential pair; used with COMA for true differential routing |
| 3, 13, 14, N.C. | No connection | Not internally bonded; must remain unconnected to avoid parasitic coupling or latch-up risk |
| 4–11, NO8B–NO1B | Analog inputs B (bidirectional) | Eight dedicated inputs for second differential channel; support ±15V signal swing |
| 12, GND | Ground reference | Logic and substrate reference; must be low-impedance return path for digital and analog sections |
| 15–17, A2–A0 | Address inputs | 3-bit binary select for 8-channel addressing; TTL/CMOS compatible (0.8V/2.4V thresholds) |
| 18, EN | Enable input | Active-high control; disables all switches when low, reducing leakage and power consumption |
| 19–26, NO1A–NO8A | Analog inputs A (bidirectional) | Eight inputs for first differential channel; electrically isolated from NOx-B pins except via shared V+/V- |
| 27, V- | Negative supply voltage input | Accepts –4.5V to –20V; sets lower rail for bipolar operation and defines analog common-mode range |
| 28, COMA | Differential output A | Primary output for first channel; paired with COMB to deliver fully differential switched signals |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX307EWI | Same pinout and function, but rated for –40°C to +85°C only; lower ESD rating (1500V vs. >2000V) | Suitable for commercial/industrial environments; not qualified for extended military temperature range | Select MAX307MWI/PR when operating below –40°C or above +85°C, or where enhanced ESD robustness is required. |
| ADG507AKRZ | Differential 8-channel CMOS mux; 125Ω RON (typ), 25nA INO(OFF) at +85°C, no guaranteed RON matching spec | Higher on-resistance and leakage limit use in ultra-low-level precision systems | Choose MAX307MWI/PR for applications requiring <5Ω matching, <100Ω RON, and <2.5nA leakage at +85°C. |
Compared with MAX307EWI and ADG507AKRZ, the MAX307MWI/PR delivers superior parametric guarantees for extreme-temperature operation, tighter on-resistance matching, lower leakage, and higher ESD tolerance - making it the preferred choice for aerospace, defense, and high-reliability instrumentation where specification margins directly impact system accuracy and field lifetime.

FAQ
What is the operating temperature range of the MAX307MWI/PR?
The MAX307MWI/PR is specified for operation from –55°C to +125°C. This extended temperature range is validated per MIL-STD-883 methods and makes the device suitable for aerospace, defense, and downhole industrial applications where ambient conditions exceed commercial or industrial grade limits. The MAX307MWI/PR achieves this rating using Maxim's enhanced 44V silicon-gate process and hermetic-grade packaging assembly.
Does the MAX307MWI/PR support single-supply operation?
Yes, the MAX307MWI/PR supports single-supply operation from +5V to +30V. In this configuration, V– must be connected to ground. The device maintains rail-to-rail analog signal handling (0V to V+) and retains TTL/CMOS logic compatibility. Performance parameters such as on-resistance and leakage are characterized across the full supply range, including at +5V, though transition time increases slightly at minimum supply.
How does the MAX307MWI/PR differ from the MAX306 in functionality?
The MAX307MWI/PR is a differential 2-of-8 analog multiplexer with two independent outputs (COMA and COMB), whereas the MAX306 is a single-ended 1-of-16 device with one common output (COM). The MAX307MWI/PR uses only three address bits (A0–A2) to select eight differential channels, while the MAX306 requires four (A0–A3). Both share identical electrical specs (RON, leakage, charge injection), but their pinouts, truth tables, and system-level routing capabilities are fundamentally different.
Is the MAX307MWI/PR pin-compatible with industry-standard alternatives like the DG407?
Yes, the MAX307MWI/PR is a plug-in upgrade for the DG407 and DG507A, sharing identical pinout, function, and package dimensions in the 28-pin Wide SO variant. No PCB layout changes are required. Key improvements include lower on-resistance (<100Ω vs. ~120Ω), tighter matching (<5Ω vs. ~10Ω), reduced charge injection (<10pC vs. ~25pC), and enhanced ESD protection (>2000V vs. ~1000V).
What is the maximum analog signal voltage the MAX307MWI/PR can handle?
The MAX307MWI/PR supports analog signals from V– to V+, i.e., rail-to-rail operation. With ±15V supplies, the full analog range is –15V to +15V. Under single +15V supply (V– = GND), the range is 0V to +15V. Absolute maximum ratings permit signals up to (V– – 2V) to (V+ + 2V), but sustained operation beyond rails risks diode conduction and increased leakage - design should stay within specified VNO/VCOM limits per datasheet.
