Product details
Overview
MAX4558CSE 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, 1nA off-leakage at +25°C, and TTL/CMOS-compatible digital inputs-used in battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4558CSE datasheet, MAX4558CSE pinout, MAX4558CSE application, or MAX4558CSE equivalent, this page delivers verified electrical specs, package mapping to 16-pin narrow SO, functional truth table alignment, ESD latchup behavior, and real-world switching performance metrics including <93dB crosstalk and <96dB off-isolation at 100kHz.
Technical Context
The MAX4558CSE 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 uses bidirectional SCRs for ESD protection on all X/X₀–X₇ pins, triggering within nanoseconds during ±15kV HBM events and latching until current falls below 70–110mA holding thresholds.
It supports dual-supply operation (±2V to ±6V) or single-supply (+2V to +12V), with analog signal range spanning rail-to-rail. Digital logic thresholds are fixed at +0.8V/+2.4V, ensuring compatibility across +5V and ±5V supply configurations without level-shifting circuitry.
Key Specifications

|---|---|
| Configuration | 8-to-1 analog multiplexer with common output (X) and eight inputs (X₀–X₇) |
| Supply Range | ±2V to ±6V dual or +2V to +12V single-enables direct interfacing with Li-ion, 3.3V, and 5V systems |
| On-Resistance | 160Ω max at ±5V-ensures minimal signal attenuation and voltage drop in precision analog paths |
| Off-Leakage Current | 1nA max at +25°C-critical for high-impedance sensor front-ends and battery-life-sensitive designs |
| ESD Protection | ±15kV HBM, ±12kV IEC air-gap, ±8kV IEC contact-eliminates need for external TVS diodes in portable equipment |
| Crosstalk / Off-Isolation | <−93dB / <−96dB at 100kHz (50Ω)-supports clean multi-channel audio and instrumentation signal separation |
| Switching Speed | tON = 150ns max, tOFF = 120ns max (RL = 300Ω, CL = 35pF)-suitable for multiplexed ADC sampling up to ~2MHz |

| 13 | X₆ | Analog input channel 6-same leakage, capacitance, and distortion specs as X₀–X₇ |
| 14 | X₇ | Analog input channel 7-final channel in 8:1 mux; identical dynamic performance (tON/tOFF) |
| 15 | X | Common analog output-bidirectional; connects to selected input when ENABLE = low |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1408BRUZ | 8:1 mux with 4.7Ω RON, ±15V supply, no integrated ESD protection | Requires external ±15kV ESD protection; suited for high-voltage industrial signal chains | Select ADG1408BRUZ when higher supply voltage (>±6V) and lower on-resistance are prioritized over integrated ESD robustness. |
| 74HC4051D,653 | 8:1 mux with 120Ω RON at +4.5V, no ESD rating, 20V max supply | Lacks guaranteed ±15kV ESD protection; not qualified for high-ESD environments | Choose 74HC4051D,653 only in cost-sensitive, low-risk consumer applications where external ESD mitigation is acceptable. |
Compared with ADG1408BRUZ and 74HC4051D,653, the MAX4558CSE uniquely integrates ±15kV HBM ESD protection without external components while maintaining rail-to-rail operation down to +2V supply-making it optimal for space-constrained, battery-powered, and field-deployed analog signal routing.

FAQ
What is the maximum supply voltage for MAX4558CSE in single-supply operation?
The MAX4558CSE supports single-supply operation from +2V to +12V. At +12V, its analog signal range extends rail-to-rail (0V to +12V), and digital inputs remain TTL/CMOS-compatible with logic thresholds scaling to ~3.1V high. Operation beyond +12V risks permanent damage per Absolute Maximum Ratings.
Does MAX4558CSE require external ESD protection components?
No. The MAX4558CSE integrates on-chip bidirectional SCRs on all analog pins (X₀–X₇ and X), certified to ±15kV HBM, ±12kV IEC air-gap, and ±8kV IEC contact discharge. This eliminates the need for external TVS diodes or RC filters in most portable and handheld applications.
How does the ENABLE pin function on MAX4558CSE?
The ENABLE pin on MAX4558CSE is active-low. When pulled low, the device enables channel selection via A/B/C address lines. When driven high, all internal switches open regardless of address state-providing hardware-level channel isolation independent of control logic.
What is the on-resistance match between channels for MAX4558CSE?
The MAX4558CSE guarantees ΔRON ≤ 6Ω between any two channels at +25°C with ±5V supplies. This tight matching ensures consistent gain and minimal channel-to-channel error in precision multiplexed measurement systems.
Can MAX4558CSE operate from a +3.3V single supply?
Yes. The MAX4558CSE operates from +2.7V to +3.6V single supply, with on-resistance of 400Ω max and logic thresholds of +0.5V/+1.5V. It maintains 1nA off-leakage and supports rail-to-rail analog signals from 0V to +3.3V-ideal for modern low-voltage embedded systems.
