Analog Devices Inc./Maxim Integrated MAX4558EEE

Overview

MAX4558EEE 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 on-resistance at ±5V, 2Ω typical R_ON match between channels, and 1nA off-leakage at +25°C - deployed in battery-powered audio routing and low-voltage data-acquisition systems.

For engineers reviewing the MAX4558EEE datasheet, MAX4558EEE pinout, MAX4558EEE application, or MAX4558EEE equivalent, this device supports high-ESD environments requiring precise analog signal selection, low distortion (<0.02%), high off-isolation (–96dB), and TTL/CMOS-compatible digital control across industrial temperature ranges.

Technical Context

The MAX4558EEE implements a single 8-channel analog multiplexer controlled by three address lines (A/B/C) and an active-low ENABLE input, operating with bidirectional signal flow and break-before-make switching to prevent channel shorting. Its internal ESD protection uses on-chip SCRs tied to GND on all X/Y/Z and X_/Y_/Z_ pins, enabling ±15kV HBM and ±12kV IEC air-gap discharge immunity without latchup.

It supports dual-supply operation (±2V to ±6V) or single-supply (+2V to +12V), with logic thresholds fixed at +0.8V/+2.4V for TTL/CMOS compatibility. Analog signal range extends fully rail-to-rail, and leakage currents are guaranteed over –40°C to +85°C with production-tested 1nA off-leakage at +25°C.

FAQ

What is the maximum supply voltage range supported by the MAX4558EEE?

The MAX4558EEE 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. The device is characterized for guaranteed performance across its full –40°C to +85°C operating range under these supply conditions.

Does the MAX4558EEE require external ESD protection components?

No, the MAX4558EEE does not require external ESD protection components. It integrates on-chip silicon-controlled rectifiers (SCRs) on all analog I/O pins (X0–X7, X) that provide ±15kV Human Body Model and ±12kV IEC 1000-4-2 air-gap ESD protection. These SCRs clamp transients directly to GND, eliminating reliance on supply-rail diodes and preventing supply coupling - a key advantage over unprotected alternatives like the TMUX1308PWR.

How does the MAX4558EEE handle rail-to-rail analog signals?

The MAX4558EEE supports true rail-to-rail analog signal operation: input and output voltages can swing from VEE to VCC without distortion or clipping. This is enabled by its CMOS transmission-gate architecture and optimized threshold design. When VEE = GND and VCC = +5V, signals from 0V to +5V pass unattenuated; with ±5V supplies, signals from –5V to +5V are fully supported - critical for interfacing with op-amps, sensors, and DACs operating at supply rails.

What is the guaranteed on-resistance match between channels for the MAX4558EEE?

The MAX4558EEE guarantees a maximum on-resistance match (ΔR_ON) of 6Ω over temperature (–40°C to +85°C), with a typical value of 2Ω at +25°C. This specification is measured as R_ON(max) – R_ON(min) across all eight channels under identical conditions (VCC = ±5V, I_X = 1mA, V_{X_} = ±3V). Tight matching ensures consistent gain and minimal channel-to-channel error in calibrated measurement systems.

Is the MAX4558EEE pin-compatible with standard logic-family multiplexers?

Yes, the MAX4558EEE is pin-compatible with the industry-standard 74HC4051 analog multiplexer in the same 16-pin QSOP package. Pin assignments for VCC, GND, ENABLE, A/B/C address lines, and analog I/O (X0–X7, X) align directly - enabling drop-in replacement without PCB modification. However, the MAX4558EEE adds ±15kV ESD protection, lower leakage (1nA vs. ~100nA), and tighter R_ON matching not found in legacy HC-series devices.
