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, 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 MAX4558EPE+ datasheet, MAX4558EPE+ pinout, MAX4558EPE+ application, or MAX4558EPE+ equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative parts for ESD-hardened analog switching in portable and industrial signal-path designs.
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 supports bidirectional signal flow and operates across ±2V to ±6V dual supplies or +2V to +12V single supply, maintaining rail-to-rail analog voltage range.
ESD protection uses on-chip SCRs between X/Y/Z/X_/Y_/Z_ pins and GND - triggering within nanoseconds during ±15kV HBM events - while internal diodes limit surge current into VCC/VEE. Holding current is 110mA (+25°C, positive) and 95mA (negative), requiring external current limiting below 70mA at +85°C for guaranteed SCR turn-off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Configuration | 8-to-1 multiplexer with 3-bit address decoding (A/B/C) and enable control |
| Supply Range | ±2V to ±6V dual or +2V to +12V single - enables operation in low-voltage battery and wide-range industrial rails |
| On-Resistance | 160Ω max at ±5V - ensures minimal signal attenuation and gain error in precision sensor or audio paths |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance measurement circuits (e.g., pH sensors, thermocouples) |
| ESD Protection | ±15kV HBM, ±12kV IEC air-gap, ±8kV IEC contact - eliminates need for external TVS in handheld medical or test equipment |
| Switching Speed | 150ns turn-on / 120ns turn-off (±5V, 35pF load) - supports audio-band and moderate-speed data acquisition up to ~2MHz |
| THD & Isolation | <0.02% THD (600Ω), –96dB off-isolation (50Ω) - maintains fidelity in line-level audio and instrumentation signal routing |
Pinout & Package
MAX4558EPE+ is housed in a 16-pin plastic DIP package (0.300" width), RoHS-compliant, with through-hole mounting and industry-standard footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–2, 4–5, 12–15 | Analog Inputs X0–X7 | Eight bidirectional analog signal inputs; selectable as channel source under A/B/C/ENABLE control |
| 3 | Analog Output X | Common output node; connects to one selected X0–X7 input when ENABLE = low and address matches |
| 6 | ENABLE | Active-low digital enable; drives all switches open (high-Z) when logic 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 SCR clamping |
| 9–11 | A, B, C | 3-bit binary address inputs; decode X0–X7 selection (C = MSB, A = LSB) |
| 16 | VCC | Positive analog/digital supply; powers internal logic, level translators, and switch gates |

IC Role / Device Role / Timing Role: ESD-hardened multiplexer isolating DUT signals from measurement instruments during hot-plug connection cycles. Use Value: SCR-based ±15kV protection survives repeated bench-level ESD events without degradation; no external clamps reduce BOM count and layout area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1408BRUZ | 40Ω on-resistance (±15V supply), –40°C to +125°C rating, SPI interface instead of parallel address lines | Higher voltage operation and extended temperature range; requires serial control firmware overhead | Select for high-precision, high-temp industrial systems where lower RON and wider voltage range outweigh parallel interface simplicity |
| TS5A23157DGSR | 0.9Ω on-resistance (3.3V), no integrated ESD protection beyond 2kV HBM, 10ns switching speed | Ultra-low RON and fast switching for high-speed digital signal routing; lacks ±15kV ESD hardening | Select for cost-sensitive consumer audio switches where external ESD protection is acceptable and sub-1Ω RON is critical |
Compared with ADG1408BRUZ and TS5A23157DGSR, the MAX4558EPE+ uniquely balances robust ±15kV ESD immunity, 160Ω RON at ±5V, and simple 3-wire parallel addressing - making it optimal for portable, battery-powered, and field-deployed analog multiplexing where reliability and ease of integration are prioritized over ultra-low resistance or extreme temperature range.

FAQ
What is the maximum supply voltage range supported by the MAX4558EPE+?
The MAX4558EPE+ 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. Operation outside these ranges risks permanent damage. The device maintains rail-to-rail analog signal handling across the full specified supply range, enabling flexibility in both low-voltage battery and higher-voltage industrial applications.
Does the MAX4558EPE+ require external ESD protection components?
No, the MAX4558EPE+ does not require external ESD protection components on its X0–X7, X, and ENABLE pins. It integrates on-chip SCRs providing ±15kV Human Body Model, ±12kV IEC 1000-4-2 air-gap, and ±8kV contact discharge protection. This eliminates TVS diodes or RC networks in most handheld and benchtop applications - though external current limiting below 70mA is recommended at +85°C to ensure SCR turn-off after an event.
What is the typical on-resistance matching between channels of the MAX4558EPE+?
The MAX4558EPE+ guarantees on-resistance matching (ΔRON) of ≤2Ω typical and ≤6Ω maximum at +25°C under ±5V supplies. This tight matching minimizes gain error when sequentially scanning multiple sensors (e.g., thermocouples or strain gauges) into a shared amplifier or ADC, ensuring consistent signal scaling across all eight channels without per-channel calibration.
Can the MAX4558EPE+ operate with a +3.3V single supply?
Yes, the MAX4558EPE+ operates with a +3.3V single supply. At VCC = +3.3V, typical on-resistance is 220Ω (max 450Ω), logic thresholds are VIH = +1.5V and VIL = +0.5V, and leakage remains ≤1nA at +25°C. Switching times increase to ~350ns (tON), but performance remains suitable for audio and medium-speed data acquisition. Full specifications for +3V operation are documented in the datasheet's "Electrical Characteristics-Single +3V Supply" table.
How does the ENABLE pin function on the MAX4558EPE+?
The ENABLE pin on the MAX4558EPE+ is active-low. When pulled low (≤0.8V), the device enables analog switching based on A/B/C address inputs. When driven high (≥2.4V), all internal switches open simultaneously, placing X0–X7 and X in high-impedance state. This allows safe signal isolation during power-up/down sequencing or system standby - critical in battery-powered devices to prevent backfeeding or leakage paths.
