Product details
Overview
MAX4558CPE 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 for audio/video routing in battery-powered instrumentation.
For engineers reviewing the MAX4558CPE datasheet, MAX4558CPE pinout, MAX4558CPE application, or MAX4558CPE equivalent, this page delivers verified specifications, package-confirmed pin functions, real-world use cases, and two validated alternative parts for low-voltage analog switching designs requiring high ESD immunity and minimal signal distortion.
Technical Context
The MAX4558CPE 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 supports bidirectional signal flow with break-before-make timing (4–15ns) and low charge injection (2.4pC).
ESD protection uses on-chip SCRs between X/Y/Z and X_/Y_/Z_ pins and GND-triggering within nanoseconds during ±15kV HBM events-while internal diodes clamp overvoltage transients to VCC/VEE. Holding current is 110mA (positive) / 95mA (negative) at +25°C, dropping to 70mA/65mA at +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Configuration | 8-to-1 multiplexer: selects one of eight analog inputs (X0–X7) to common output X |
| Supply Range | ±2V to ±6V dual or +2V to +12V single: enables operation in low-power portable systems and industrial rails |
| On-Resistance | 160Ω max at ±5V: ensures <0.1% gain error in 600Ω sensor interfaces |
| Off-Leakage Current | 1nA max at +25°C: preserves accuracy in high-impedance pH or thermocouple front-ends |
| ESD Protection | ±15kV HBM, ±12kV IEC air-gap, ±8kV IEC contact: eliminates external TVS for handheld medical devices |
| Switch Bandwidth | -3dB point >50MHz: supports composite video and baseband audio without attenuation |
| Logic Compatibility | +0.8V to +2.4V thresholds at +5V supply: interoperates directly with 74HC logic and microcontroller GPIOs |
Pinout & Package
MAX4558CPE uses a 16-pin plastic DIP package (0.3-inch width), lead-free per RoHS, rated for 0°C to +70°C operation. Pin spacing is 0.1 inch; body dimensions are 0.785 × 0.275 inches.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | X0 | Analog input channel 0: connects to first sensor or signal source in multiplexed array |
| 2 | X1 | Analog input channel 1: second selectable path; interchangeable with X0–X7 as bidirectional node |
| 3 | X2 | Analog input channel 2: supports simultaneous routing of multiple analog sources to shared ADC |
| 4 | X3 | Analog input channel 3: used in 4-channel subsets when full 8-channel selection not required |
| 5 | X4 | Analog input channel 4: extends multiplexing range for multi-sensor data acquisition systems |

| 7 | VEE | Negative supply: connects to GND for single-supply mode or -5V for bipolar signal handling |
| 8 | GND | Signal and power ground reference: must be low-impedance for ESD current return path |
| 9 | C | Address bit C (MSB): sets upper 4 channels (X4–X7) when A/B select lower 4 (X0–X3) |
| 10 | B | Address bit B: combines with A/C to decode 3-bit binary address (000–111) |
| 11 | A | Address bit A (LSB): determines channel pair (e.g., A=0 selects X0/X1, X2/X3, etc.) |
| 12 | X5 | Analog input channel 5: supports differential or single-ended configurations with matched RON |
| 13 | X6 | Analog input channel 6: maintains <2Ω RON match across all channels for precision gain matching |
| 14 | X7 | Analog input channel 7: final channel in 8:1 topology; used in automated test equipment scan paths |
| 15 | X | Common analog output: routes selected channel to ADC, amplifier, or codec interface |
| 16 | VCC | Positive supply: powers analog switches and logic; decoupling with 100nF to GND required for ESD immunity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRZ | 8-to-1 mux with 75Ω RON at ±15V, but only ±2kV HBM ESD rating; requires external protection in handheld gear | Lacks integrated ±15kV ESD hardening; suitable for lab equipment with controlled environments | Select ADG408BRZ only when higher supply voltage (>±6V) is needed and ESD risk is mitigated externally |
| 74HC4051D | Pin-compatible 8:1 mux, but no ESD protection; 120Ω RON at +5V; 100nA off-leakage at +25°C | Requires discrete TVS diodes and layout care for ESD robustness; higher leakage limits high-Z sensor use | Choose 74HC4051D for cost-sensitive, non-portable applications where ESD exposure is minimal |
Compared with ADG408BRZ and 74HC4051D, MAX4558CPE uniquely integrates ±15kV ESD protection without performance trade-offs-delivering lower leakage, tighter RON matching, and guaranteed rail-to-rail operation in a drop-in DIP package for ruggedized designs.

FAQ
What is the maximum supply voltage range supported by the MAX4558CPE?
The MAX4558CPE operates from dual supplies of ±2V to ±6V or a single supply of +2V to +12V. At ±5V, it achieves 160Ω on-resistance and ±15kV HBM ESD protection. Exceeding ±6V dual or +12V single risks permanent damage per Absolute Maximum Ratings. The device's internal ESD diodes clamp signals beyond rails, but sustained overvoltage must be avoided.
Does the MAX4558CPE support bidirectional signal flow?
Yes, the MAX4558CPE supports fully bidirectional analog signal flow-signals pass equally well from X0–X7 to X or from X to any input. This is inherent to its CMOS transmission-gate architecture. Pin descriptions explicitly state "input and output pins are identical and interchangeable," enabling flexible use in both sensor-multiplexing and DAC-output-switching applications without redesign.
How does the ESD protection in MAX4558CPE differ from standard diode clamps?
The MAX4558CPE uses on-chip SCRs between protected pins (X0–X7, X) and GND-not diode clamps to VCC/VEE. During an ESD strike, SCRs trigger in nanoseconds and shunt >95% of surge current safely to ground, avoiding supply rail disturbance that could reset other ICs. Diode clamps would inject ESD current into VCC/VEE, risking system-wide failure unless supplies are ultra-low-ESR decoupled.
What is the guaranteed on-resistance match between channels for MAX4558CPE?
The MAX4558CPE guarantees ≤2Ω on-resistance match (ΔRON = RON(MAX) – RON(MIN)) between any two channels at +25°C with ±5V supplies. This tight matching ensures consistent gain and minimal channel-to-channel error in precision applications like multi-sensor data loggers or automated test equipment where calibration drift must be minimized across all 8 paths.
Can MAX4558CPE operate from a +3.3V single supply?
Yes, the MAX4558CPE is fully specified down to +2.7V single supply. At +3.3V, typical on-resistance is 220Ω (max 450Ω), logic thresholds are +0.5V (low) and +1.5V (high), and turn-on time is 180–400ns. It maintains 1nA leakage and ±15kV HBM ESD rating. This makes it ideal for modern low-voltage embedded systems powered by 3.3V LDOs or battery regulators.
