Product details
Overview
MAX307EWI+T from Maxim Integrated is a precision, differential 2-of-8 CMOS analog multiplexer designed for high-fidelity signal routing in bipolar or single-supply systems. It delivers <100Ω on-resistance (max), <5Ω channel-to-channel matching, <10pC charge injection, <2.5nA NO off-leakage at +85°C, and operates from ±4.5V to ±20V or +5V to +30V - enabling use in military radios, test equipment, and guidance systems.
For engineers reviewing the MAX307EWI+T datasheet, MAX307EWI+T pinout, MAX307EWI+T application, or MAX307EWI+T equivalent, this page provides verified electrical specifications, package mapping to 28-pin Wide SO, functional pin roles, real-world application context, and two validated alternative parts with documented technical and application differences.
Technical Context
The MAX307EWI+T implements a dual 8-channel differential 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 rail-to-rail analog signal handling across ±15V dual supplies or 0V–12V single supplies.
It guarantees break-before-make switching (tOPEN ≤ 40ns), fast transition time (tTRANS ≤ 400ns), and low dynamic crosstalk (−92dB at 100kHz), making it suitable for sample-and-hold circuits and audio routing where signal integrity and channel isolation are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V (dual supply) or 0V to +12V (single supply): supports full-rail signal routing without clipping. |
| On-Resistance (RON) | <100Ω max at +25°C, <125Ω over −40°C to +85°C: minimizes voltage drop and gain error in precision measurement paths. |
| RON Matching | <5Ω max between channels: ensures matched gain/attenuation in differential or multi-channel sensing. |
| Charge Injection | <10pC: reduces settling error and pedestal distortion in sample-and-hold and ADC front-end applications. |
| NO Off-Leakage | <2.5nA at +85°C: preserves accuracy in high-impedance sensor interfaces and battery-operated systems. |
| Transition Time | <400ns over temperature: enables reliable multiplexing in sub-microsecond timing-critical systems. |
| ESD Protection | >2000V HBM: improves robustness during board handling and system integration without external protection. |
Pinout & Package
MAX307EWI+T is housed in a 28-pin Wide SO (SOIC-W) package with 300 mil body width and standard gull-wing leads. Pin pitch is 1.27 mm; package meets RoHS requirements and is compatible with standard reflow profiles (Pb-free: +260°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 28 | V+, V− | Positive and negative supply rails: support ±4.5V to ±20V operation; V− must be connected even in single-supply mode (V− = GND). |
| 2, 3, 13, 14 | N.C. | No internal connection: left unconnected per design; no routing or grounding required. |
| 4–11 | NO8B–NO1B | Differential input group B: bidirectional analog terminals for one 8-channel set; paired with COMB. |
| 12 | GND | Ground reference: serves as logic and analog return; requires low-impedance connection to system ground plane. |
| 15–17 | A2, A1, A0 | Binary address inputs: select one of eight channels in each differential group (A2 MSB, A0 LSB). |
| 18 | EN | Active-high enable: disables all switches when low; TTL/CMOS-compatible (VIH ≥ 2.4V, VIL ≤ 0.8V). |
| 19–26 | NO1A–NO8A | Differential input group A: bidirectional analog terminals for second 8-channel set; paired with COMA. |
| 27 | COMA | Common output A: connects selected NOxA channel to this terminal; used for differential pair A. |
| 28 | COMB | Common output B: connects selected NOxB channel to this terminal; used for differential pair B. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX307CWI | Same functionality and pinout, but rated for 0°C to +70°C only; lower temp grade reduces cost and long-term reliability margin. | Suitable for commercial-grade test fixtures or non-military embedded systems without extended temperature requirements. | Select MAX307CWI only if ambient operating temperature stays within 0°C–70°C and lifecycle assurance is not critical. |
| ADG507AKRZ | 8-channel differential CMOS mux with 120Ω RON (typ), higher leakage (10nA @ +85°C), and no guaranteed RON matching spec. | Better suited for general-purpose industrial control than precision metrology due to looser matching and higher leakage. | Choose ADG507AKRZ when absolute channel matching is unnecessary and cost sensitivity outweighs leakage or flatness requirements. |
Compared with MAX307EWI+T, MAX307CWI sacrifices extended temperature capability for lower unit cost, while ADG507AKRZ trades guaranteed matching and ultra-low leakage for broader vendor availability and simplified sourcing - neither offers plug-in equivalence in high-reliability or precision measurement contexts.

FAQ
What is the operating temperature range of the MAX307EWI+T?
The MAX307EWI+T is specified for operation from −40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and Electrical Characteristics sections of the official Maxim Integrated datasheet Rev 5 (3/2016). The "E" suffix denotes the −40°C to +85°C grade, and the "WI" package code confirms the 28-pin Wide SO variant. This rating applies across all guaranteed parameters including on-resistance, leakage, and switching speed.
Does the MAX307EWI+T support single-supply operation?
Yes, the MAX307EWI+T supports single-supply operation from +5V to +30V. Per the Applications Information section, V− must be tied to GND in this configuration. Key specs such as analog signal range (0V to +12V at +12V supply), on-resistance (120Ω–175Ω), and leakage remain fully characterized and guaranteed under single-supply conditions, as shown in the Electrical Characteristics-Single Supply table on page 4 of the datasheet.
Is the MAX307EWI+T pin-compatible with the DG407 or DG507A?
Yes, the MAX307EWI+T is a plug-in upgrade for the industry-standard DG407 and DG507A, as explicitly stated in the Benefits and Features section. Pin functions, pin count (28), and physical layout match exactly - enabling direct replacement without PCB modification. However, the MAX307EWI+T improves on key parameters: lower on-resistance (<100Ω vs. ~150Ω), tighter RON matching (<5Ω vs. unspecified), and higher ESD rating (>2000V vs. ~200V).
What is the maximum analog signal voltage the MAX307EWI+T can handle?
The MAX307EWI+T supports analog signals from V− to V+ - up to ±15V with dual supplies or 0V to +12V with a +12V single supply. Absolute maximum ratings allow VNO/VCOM to swing (V− − 2V) to (V+ + 2V), but guaranteed performance (e.g., RON flatness, leakage) is specified only within the rated analog signal range. Exceeding ±15V or +12V risks violating the ±44V V+–V− differential limit and may cause permanent damage.
How does the MAX307EWI+T differ from the MAX306EWI+T?
The MAX307EWI+T is a differential 2-of-8 analog multiplexer with two independent COM outputs (COMA and COMB) and two groups of eight NO inputs each. In contrast, the MAX306EWI+T is a single-ended 1-of-16 mux with one COM and sixteen NO inputs. Their pinouts differ significantly: MAX307 uses A0–A2 and EN for addressing, while MAX306 adds A3. Neither is functionally or pin-compatible with the other - they serve distinct routing architectures (differential vs. single-ended, dual-output vs. single-output).
