Product details
Overview
MAX4559CSE from Analog Devices is a dual 4-to-1 CMOS analog multiplexer configured for bidirectional signal routing in low-voltage systems, featuring ±15kV HBM ESD protection on all X/Y signal pins, 160Ω typical on-resistance at ±5V supply, and rail-to-rail analog signal handling from ±2V to ±6V or +2V to +12V single supply. It serves in audio/video switching, battery-powered instrumentation, and high-ESD industrial interfaces.
For engineers reviewing the MAX4559CSE datasheet, MAX4559CSE pinout, MAX4559CSE application, or MAX4559CSE equivalent, key selection criteria include guaranteed RON match (2Ω typ), <−93dB crosstalk at 100kHz, 1nA off-leakage at +25°C, TTL/CMOS-compatible logic thresholds, and narrow SO-16 package compatibility with legacy 74HC4052 layouts.
Technical Context
The MAX4559CSE implements two independent 4-channel analog multiplexers sharing common address lines (A, B) and enable control, each with separate X and Y output terminals. Its internal architecture uses CMOS transmission gates with integrated SCR-based ESD protection on all analog I/O pins (X₀–X₃, Y₀–Y₃, X, Y), enabling robust operation without latchup under ±15kV HBM stress.
Switching is controlled by binary-decoded A/B inputs and an active-low ENABLE pin tied to GND for operation. The device supports dual-supply (±5V) and single-supply (+5V) modes, with logic thresholds fixed at +0.8V/+2.4V - ensuring interoperability with standard TTL/CMOS drivers without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual 4-to-1 analog multiplexer: two independent 4-input, 1-output switch banks (X and Y sections) |
| On-Resistance (RON) | 160Ω max at ±5V supply - ensures minimal signal attenuation and gain error in precision sensor or audio paths |
| RON Match | 2Ω typical between channels - critical for matched gain/phase in differential or multi-channel acquisition systems |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance sensor front-ends and battery-monitoring circuits |
| Crosstalk | <−93dB at 100kHz (50Ω) - prevents interference between concurrently routed analog signals |
| ESD Protection | ±15kV HBM, ±12kV IEC 1000-4-2 air-gap, ±8kV contact - eliminates need for external TVS diodes in portable or field-deployed equipment |
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports operation from Li-ion battery (3.0–4.2V) up to industrial 10V rails |
Pinout & Package
MAX4559CSE is housed in a 16-pin narrow SOIC (Small Outline Integrated Circuit) package, 3.9mm body width, 1.27mm pitch, RoHS-compliant, with exposed pad not present. Pin 1 marked via notch or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | X₀, X₁, X₂, X₃ | Analog inputs to first multiplexer bank (X section); bidirectional, rail-to-rail capable |
| 3 | X | Common output terminal for X-section multiplexer; connects selected X₀–X₃ input |
| 9, 10, 11 | C, B, A | Digital address inputs (C unused on MAX4559); decode 00–11 to select X₀–X₃ and Y₀–Y₃ |
| 6 | ENABLE | Active-low digital enable; tie to GND to activate switches; open or high disables all paths |
| 7 | VEE | Negative analog supply; connect to GND for single-supply operation (+2V to +12V) |
| 8 | GND | Logic and analog reference ground; must be low-impedance return path for ESD current |
| 12, 13, 14, 15 | Y₀, Y₁, Y₂, Y₃ | Analog inputs to second multiplexer bank (Y section); electrically isolated from X section |
| 16 | VCC | Positive analog/digital supply; powers internal logic translators and switch gates |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC4052D | No integrated ESD protection; RON = 120Ω typ at 5V but degrades significantly below 4.5V; no dual-supply support | Suitable only in benign, board-level environments with external protection; cannot replace MAX4559CSE in field-connected or battery-operated systems | Select when cost is primary constraint and ESD risk is mitigated externally; verify RON variation over full VCC range |
| ADG708BRUZ | Single 8-to-1 mux (not dual 4-to-1); 4Ω RON at 3V but rated only to +5.5V supply; no ±15kV HBM rating | Requires redesign for dual-path routing; lacks certified ESD robustness for industrial connectors or handheld use | Choose for ultra-low RON in low-voltage (≤3.6V), space-constrained applications where dual-bank functionality is unnecessary |
Compared with 74HC4052D and ADG708BRUZ, the MAX4559CSE uniquely delivers certified ±15kV ESD protection, dual independent 4-to-1 routing in one package, and guaranteed performance across ±2V to ±6V supplies - making it the only option for ruggedized, multi-channel analog signal management without external protection or layout modification.

FAQ
What is the maximum supply voltage range supported by the MAX4559CSE?
The MAX4559CSE operates from dual supplies of ±2V to ±6V or a single supply of +2V to +12V. Absolute maximum ratings specify VCC and VEE up to ±6V for dual mode or VCC up to +13V for single mode, with all analog signals clamped by internal diodes if exceeding supply rails. This range supports both low-voltage battery operation and higher industrial rails without external regulation.
Does the MAX4559CSE require external ESD protection components?
No, the MAX4559CSE does not require external ESD protection components. It integrates on-chip SCR-based protection rated for ±15kV per Human Body Model (HBM) on all X and Y analog pins, plus ±12kV air-gap and ±8kV contact discharge per IEC 1000-4-2. This eliminates the need for discrete TVS diodes or RC filters in most end-equipment designs, reducing BOM count and board area.
How does the ENABLE pin function on the MAX4559CSE?
The ENABLE pin (Pin 6) is an active-low digital control input. When pulled low (≤0.8V), the MAX4559CSE enables both multiplexer banks and allows channel selection via address inputs A and B. When held high (≥2.4V) or left floating, all analog paths are disabled (open-circuit state). For reliable operation, tie ENABLE directly to GND or drive with a clean logic signal; avoid high-impedance states.
Is the MAX4559CSE pin-compatible with the 74HC4052?
Yes, the MAX4559CSE is pin-compatible with the industry-standard 74HC4052 in the same narrow SO-16 package. Pin assignments for analog inputs (X₀–X₃, Y₀–Y₃), outputs (X, Y), address lines (A, B), supply (VCC, GND, VEE), and ENABLE match exactly. This allows direct replacement without PCB modification, while adding ±15kV ESD protection and rail-to-rail operation not present in the HC4052.
What is the typical on-resistance matching between channels of the MAX4559CSE?
The MAX4559CSE guarantees a typical on-resistance match (ΔRON) of 2Ω between any two channels within the same multiplexer bank (X or Y section) at +25°C and ±5V supply. This tight matching ensures minimal gain or phase error when routing differential signals or calibrating multi-channel systems, and is verified across temperature and supply variations per datasheet specifications.
