Analog Devices Inc./Maxim Integrated MAX4558CEE+T

Overview

MAX4558CEE+T from Analog Devices is an 8-to-1 CMOS analog multiplexer with ±15kV HBM ESD protection, rail-to-rail signal handling (±6V dual or +12V single supply), 160Ω typical on-resistance at ±5V, 1nA off-leakage at +25°C, and TTL/CMOS-compatible digital inputs - used for audio/video routing in battery-powered instrumentation.

For engineers reviewing the MAX4558CEE+T datasheet, MAX4558CEE+T pinout, MAX4558CEE+T application, or MAX4558CEE+T equivalent, key selection criteria include guaranteed on-resistance matching (2Ω typ), low charge injection (2.4pC), high off-isolation (–96dB @ 50Ω), and QSOP-16 package compatibility with legacy 74HC4051 layouts.

Technical Context

The MAX4558CEE+T implements a single 8-channel analog multiplexer controlled by three address lines (A/B/C) and an active-low ENABLE input. Its internal CMOS switch architecture supports bidirectional signal flow with break-before-make timing (4–15ns) and operates across dual supplies (±2V to ±6V) or single supplies (+2V to +12V).

ESD protection uses on-chip SCRs between X/Y/Z and X_/Y_/Z_ pins and GND, triggering within nanoseconds during ±15kV HBM events. Holding current is 110mA (positive) / 95mA (negative) at +25°C, dropping to 70mA/65mA at +85°C - requiring external current limiting on connected sources to ensure automatic SCR turn-off.

FAQ

What is the maximum supply voltage range supported by the MAX4558CEE+T?

The MAX4558CEE+T operates from dual supplies of ±2V to ±6V or a single supply of +2V to +12V. Absolute maximum ratings specify VCC up to +13V and VEE down to –0.3V relative to GND. Exceeding these limits risks permanent damage due to internal diode conduction. For reliable long-term operation, stay within the recommended ranges - especially critical when using single-supply configurations where VEE is tied to GND.

Does the MAX4558CEE+T require external ESD protection components?

No, the MAX4558CEE+T does not require external ESD protection components on its X0–X7 and X pins. It integrates on-chip SCRs providing ±15kV Human Body Model (HBM) protection per IEC 1000-4-2 standards. However, system-level design must limit current into protected pins to below the SCR holding current (70mA at +85°C) to ensure automatic turn-off after an ESD event - typically achieved with series resistors on connected signal sources.

Can the MAX4558CEE+T be used with a 3.3V logic supply?

Yes, the MAX4558CEE+T supports 3.3V logic levels. Its digital inputs (A, B, C, ENABLE) have guaranteed TTL/CMOS-compatible thresholds: logic high ≥1.5V and logic low ≤0.5V when VCC = +2.7V to +3.6V. At VCC = +3.3V, the device delivers 220Ω–400Ω on-resistance and maintains 1nA off-leakage at +25°C. Ensure analog signal swing remains within VEE to VCC (e.g., 0V to +3.3V in single-supply mode) for rail-to-rail integrity.

What is the significance of the "CEE" suffix in MAX4558CEE+T?

The "CEE" suffix in MAX4558CEE+T denotes the commercial temperature grade (0°C to +70°C) and QSOP-16 package. The "+T" indicates tape-and-reel packaging for automated assembly. This variant is RoHS-compliant and moisture-sensitive level 1 - requiring no bake prior to reflow. It is functionally identical to the MAX4558CSE (SOIC-16) and MAX4558CPE (PDIP-16), differing only in package form factor and thermal characteristics.

How does the MAX4558CEE+T handle power-supply sequencing issues?

The MAX4558CEE+T includes internal diodes from each analog pin (X0–X7, X) to both VCC and VEE, limiting damage from improper supply ramp-up order. These diodes clamp overvoltage transients during sequencing but require external series resistors to limit current if VCC/VEE are unpowered while analog signals are present. For robust sequencing tolerance, tie VEE to GND in single-supply use and ensure VCC ramps before applying analog signals - avoiding sustained forward bias of internal clamps beyond ±10mA.
