Analog Devices Inc./Maxim Integrated MAX4674EEE+T

Overview

MAX4674EEE+T from Maxim Integrated is a low-voltage CMOS quad 2:1 analog multiplexer/demultiplexer with 4Ω max on-resistance at +5V, 0.4Ω max R_ON matching between channels, and 18ns max turn-on time. It operates from a single +1.8V to +5.5V supply and supports rail-to-rail signal handling in audio/video routing and low-voltage data-acquisition systems.

For engineers reviewing the MAX4674EEE+T datasheet, MAX4674EEE+T pinout, MAX4674EEE+T application, or MAX4674EEE+T equivalent, key selection criteria include guaranteed R_ON flatness (±0.8Ω), TTL/CMOS-compatible logic thresholds, -114dB crosstalk at 1MHz, and QFN-16 package compatibility with exposed pad thermal management.

Technical Context

The MAX4674EEE+T implements four independent bidirectional 2:1 analog switches controlled by a single address input (A0) and active-low enable (EN). Each switch features break-before-make timing (1ns max) and internal ESD protection diodes on all analog terminals.

Its digital interface accepts 0.8V/2.4V logic thresholds at +5V supply and scales to 0.4V/2.0V at +3V, enabling mixed-voltage system interfacing without level shifters. Analog signal range spans rail-to-rail (0V to V+), with leakage currents limited to ±0.5nA at +25°C.

Key Specifications

Pinout & Package

MAX4674EEE+T is housed in a 16-pin QFN package (4mm × 4mm × 0.9mm) with exposed pad (EP) for thermal dissipation. Pin 1 is A0 (address input); pins 2–4, 5–7, 9–11, and 12–14 form four COM/NO/NC switch groups; pin 8 is GND; pin 15 is EN (active-low enable); pin 16 is V+; EP must be connected to GND.

FAQ

What is the maximum operating supply voltage for MAX4674EEE+T?

The MAX4674EEE+T supports a single-supply range of +1.8V to +5.5V. Absolute maximum rating for V+ is +6V, but operation above +5.5V violates specifications and risks permanent damage. At +5.5V, R_ON remains within 4Ω max, and logic thresholds scale accordingly (VIH = 2.4V min, VIL = 0.8V max).

Does MAX4674EEE+T support bidirectional signal flow?

Yes, MAX4674EEE+T supports fully bidirectional analog signal flow across all COM/NO/NC terminals. Each switch channel functions identically regardless of signal direction, with identical R_ON, leakage, and capacitance specs for both forward and reverse paths-enabling flexible use in transceiver and loopback configurations.

How is the exposed pad (EP) of MAX4674EEE+T used in PCB layout?

The exposed pad of MAX4674EEE+T must be soldered to a solid PCB ground plane using ≥4 thermal vias. This connection provides critical thermal dissipation (derating factor 18.5mW/°C above +70°C) and reduces ground inductance, ensuring specified R_ON and switching speed. Leaving EP unconnected degrades thermal performance and may cause parametric drift.

What is the function of the EN pin on MAX4674EEE+T?

The EN pin (Pin 15) is an active-low global enable that overrides A0 control. When EN = high, all four switches are disabled regardless of A0 state; when EN = low, switching follows A0 logic. This allows system-level power gating and fault-safe shutdown without modifying address lines, critical in safety-critical data acquisition systems.

Can MAX4674EEE+T operate with 3.3V logic while powered from a 5V supply?

Yes, MAX4674EEE+T accepts logic inputs up to +5.5V independent of V+, allowing 3.3V logic controllers to drive A0 and EN directly when V+ = +5V. Input thresholds scale with supply: at +5V, VIH = 2.4V min ensures reliable TTL/CMOS recognition; no external level shifters are needed, simplifying mixed-voltage board design.
