Product details
Overview
The 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 typical on-resistance at ±5V, 1nA off-leakage at +25°C, and TTL/CMOS-compatible digital inputs-used for precision audio/video routing in battery-powered instrumentation.
For engineers reviewing the MAX4558EEE+ datasheet, MAX4558EEE+ pinout, MAX4558EEE+ application, or MAX4558EEE+ equivalent, this page delivers verified electrical specs, package mapping to 16-pin QSOP, ESD robustness context, and real-world selection guidance against industry-standard alternatives.
Technical Context
This device implements a single 8-channel analog multiplexer with address decoding (A/B/C) and global enable control. Its internal architecture uses CMOS transmission gates with integrated bidirectional SCR-based ESD clamps on all X/Y/Z and X_/Y_/Z_ pins-enabling ±15kV HBM protection without latchup.
It supports true rail-to-rail analog operation across ±2V to ±6V dual supplies or +2V to +12V single supply, with guaranteed on-resistance flatness (≤8Ω) and channel-to-channel RON match (≤6Ω). Digital logic thresholds are fixed at +0.8V/+2.4V, ensuring compatibility with +5V or ±5V supply configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Configuration | 8-to-1 multiplexer with 3-bit address decoding (A/B/C) and active-low ENABLE |
| Supply Range | ±2V to ±6V dual or +2V to +12V single-supports rail-to-rail signal swing up to full supply rails |
| On-Resistance (RON) | 160Ω typ at ±5V - enables low insertion loss in 600Ω audio paths and precision sensor interfaces |
| Off-Leakage Current | 1nA max at +25°C - critical for high-impedance data acquisition and low-power battery systems |
| ESD Protection | ±15kV HBM, ±12kV IEC air-gap, ±8kV IEC contact - eliminates need for external TVS diodes in portable designs |
| Switching Speed | tON = 150ns max, tOFF = 120ns max (RL = 300Ω, CL = 35pF) - suitable for multiplexed ADC sampling up to ~3MHz |
| Channel Matching | ΔRON ≤ 6Ω - ensures consistent gain/attenuation across channels in programmable gain amplifier front-ends |

| 3 | Analog Output X | Common switched output node; connects to selected X0–X7 input when ENABLE = low |
| 6 | ENABLE | Active-low global enable; drives all switches open (high-impedance) when high |
| 7 | VEE | Negative analog supply; tied to GND for single-supply operation (+2V to +12V) |
| 8 | GND | Digital/analog reference ground; must be low-impedance return path for ESD current |

FAQ
What is the maximum supply voltage rating for the MAX4558EEE+?
The MAX4558EEE+ supports dual supplies from ±2V to ±6V or a single supply from +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 ESD diode conduction.
Does the MAX4558EEE+ require external ESD protection components?
No-the MAX4558EEE+ integrates ±15kV Human Body Model ESD protection on all analog I/O pins (X0–X7, X) via on-chip SCRs. This eliminates the need for external TVS diodes in most portable and industrial applications, provided system-level current limiting meets the 70mA holding-current threshold at +85°C.
How does the MAX4558EEE+ handle rail-to-rail analog signals?
The MAX4558EEE+ passes analog signals from VEE to VCC without clipping-enabling direct interface with op-amps and ADCs operating at full supply rails. This is achieved through optimized CMOS transmission gate design and matched P/N channel sizing, maintaining low distortion (<0.02%) and flat on-resistance across the entire signal range.
What is the function of the ENABLE pin on the MAX4558EEE+?
The ENABLE pin (Pin 6) is an active-low control that globally disables all analog switches. When driven high, it forces all channels into high-impedance off-state regardless of address inputs-providing fail-safe isolation during power sequencing or fault conditions. Pulling ENABLE low activates normal multiplexer operation.
Is the MAX4558EEE+ pin-compatible with the 74HC4051?
Yes-the MAX4558EEE+ is designed as a direct pin-compatible upgrade to the 74HC4051, sharing identical pinout, address logic (A/B/C), and ENABLE functionality. This allows drop-in replacement in existing designs to add ±15kV ESD protection and improved on-resistance matching without PCB modifications.
