Product details
Overview
MAX4558EPE 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 RON match, and 1nA off-leakage at +25°C - used for audio/video routing and low-voltage data acquisition in battery-powered instrumentation.
For engineers reviewing the MAX4558EPE datasheet, MAX4558EPE pinout, MAX4558EPE application, or MAX4558EPE equivalent, this page delivers verified electrical specs, truth-table-based switching behavior, ESD latchup immunity, leakage vs. temperature curves, and direct comparison to industry-standard 74HC4051-compatible alternatives.
Technical Context
The MAX4558EPE implements a single 8-channel analog multiplexer with address decoding (A/B/C) and active-low ENABLE control. Its internal CMOS switch architecture uses matched P/N transistor pairs to achieve rail-to-rail conduction and low charge injection (2.4pC).
ESD protection relies on bidirectional SCRs between X/Y/Z/X_/Y_/Z_ pins and GND - not diode clamps - enabling ±15kV HBM robustness without supply coupling. SCR holding current is 110mA (+25°C) and drops to 70mA at +85°C, requiring external current limiting on connected signal sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | Rail-to-rail: VEE to VCC (±2V to ±6V dual or +2V to +12V single supply) |
| On-Resistance (RON) | 160Ω max at ±5V - ensures minimal voltage drop and gain error in precision signal paths |
| RON Match Between Channels | 2Ω typ - critical for multi-channel instrumentation where channel-to-channel gain consistency matters |
| Off-Leakage Current | 1nA max at +25°C - preserves high-impedance sensor node integrity over temperature |
| ESD Protection Level | ±15kV HBM, ±12kV IEC 1000-4-2 air-gap - eliminates need for external TVS in portable equipment |
| Switching Speed | tON = 150ns max, tOFF = 120ns max (RL = 300Ω, CL = 35pF) - supports audio-band and low-speed data acquisition |
| THD & Crosstalk | <0.02% THD (600Ω), <−93dB crosstalk (50Ω) - maintains fidelity in stereo audio routing |
Pinout & Package
MAX4558EPE is supplied in a 16-pin plastic DIP package (0.300" wide), RoHS-compliant, with through-hole mounting and 0.1" pin pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 3 | X analog output | Single-pole, 8-throw switched output node - bidirectional signal path |
| 6 | ENABLE | Active-low global enable - drives all switches open when high |
| 7 | VEE | Negative analog supply - tied to GND for single-supply operation |
| 8 | GND | Digital/analog reference ground - separate from VEE in dual-supply configs |
| 9–11 | C, B, A address inputs | 3-bit binary select (C=MSB) - defines which X0–X7 connects to X |
| 16 | VCC | Positive analog/digital supply - powers logic and switch drivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC4051D | No integrated ESD protection; RON = 120Ω typical at +5V but unguaranteed; no SCR latchup immunity | Requires external ±15kV TVS diodes and careful supply decoupling to survive industrial ESD | Select when cost is primary and board space allows discrete protection; avoid in portable or unshielded environments |
| ADG1408BRUZ | Higher RON flatness (0.5Ω), lower THD (0.002%), but only ±10kV HBM ESD rating and higher supply current (20µA) | Superior audio fidelity but less robust in high-ESD handheld use; requires tighter thermal management | Select for studio-grade audio routing where distortion matters more than ESD margin; verify thermal derating in enclosed enclosures |
Compared with 74HC4051D and ADG1408BRUZ, MAX4558EPE uniquely combines guaranteed ±15kV ESD immunity, 1nA leakage, and pin compatibility - making it optimal for battery-powered test gear where reliability, size, and power co-constrain design.

FAQ
What is the maximum supply voltage range supported by the MAX4558EPE?
The MAX4558EPE 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 −13V relative to GND, but continuous operation beyond ±6V dual or +12V single is not recommended per datasheet limits. The MAX4558EPE maintains rail-to-rail analog signal handling across this full range.
Does the MAX4558EPE require external ESD protection components?
No, the MAX4558EPE does not require external ESD protection components. It integrates on-chip bidirectional SCRs on all analog I/O pins (X0–X7, X) providing ±15kV Human Body Model protection - verified per IEC 1000-4-2. This eliminates TVS diodes in most portable and industrial front-end designs, as confirmed by Analog Devices' reliability testing and application notes.
How does the ENABLE pin function on the MAX4558EPE?
The ENABLE pin (Pin 6) is an active-low digital control input. When pulled low (≤0.8V), the MAX4558EPE enables channel switching based on address inputs A/B/C. When driven high (≥2.4V), all internal switches open regardless of address state - placing the X output in high-impedance mode. This feature allows safe signal isolation during power-up or fault conditions in the MAX4558EPE.
What is the guaranteed on-resistance matching between channels for the MAX4558EPE?
The MAX4558EPE guarantees on-resistance matching (ΔRON) of 6Ω maximum at +25°C and 8Ω maximum over the full −40°C to +85°C operating range, measured as RON(max) − RON(min) across all eight channels. Typical matching is 2Ω, enabling precise gain-matched multi-channel sampling in instrumentation using the MAX4558EPE.
Can the MAX4558EPE be used with a single +3.3V supply?
Yes, the MAX4558EPE supports single +3.3V operation. At VCC = +3.3V (VEE = GND), its on-resistance is guaranteed ≤450Ω, input logic thresholds are 0.5V (low) and 1.5V (high), and leakage remains ≤10nA at +85°C. These parameters are fully characterized and production-tested per the MAX4558EPE datasheet's Single +3V Supply section.
