Product details
Overview
The MAX4559ESE 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 up to ±6V. It operates across -40°C to +85°C and is widely used in audio/video switching, battery-powered instrumentation, and high-ESD industrial interfaces.
For engineers reviewing the MAX4559ESE datasheet, MAX4559ESE pinout, MAX4559ESE application, or MAX4559ESE equivalent, this device delivers verified channel matching (2Ω typ), sub-1nA off-leakage at +25°C, < -93dB crosstalk at 100kHz, and guaranteed break-before-make timing - critical for precision multiplexing in mixed-signal data acquisition and communications circuits.
Technical Context
The MAX4559ESE integrates two independent 4-to-1 analog multiplexers sharing common address lines (A, B) and enable control, with separate X and Y output buses. Each multiplexer supports true bidirectional signal flow and uses CMOS transmission-gate architecture with integrated SCR-based ESD protection on all analog I/O pins (X₀–X₃, Y₀–Y₃, X, Y).
It accepts dual supplies (±2V to ±6V) or single +2V to +12V operation, with TTL/CMOS-compatible digital inputs (0.8V/2.4V thresholds at +5V). Internal logic-level translators isolate digital control from analog rails, enabling robust switching without supply sequencing constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual 4-to-1 analog multiplexer - two independent switch banks, each selecting one of four inputs to its dedicated output (X or Y) |
| On-Resistance (RON) | 160Ω max at ±5V supply - ensures minimal signal attenuation and gain error in precision sensor or audio paths |
| RON Match Between Channels | 2Ω typical - enables accurate ratiometric measurements and matched gain across channels |
| Off-Leakage Current | 1nA max at +25°C - preserves signal integrity in high-impedance sources (e.g., piezoelectric sensors, pH electrodes) |
| Crosstalk | < -93dB at 100kHz (50Ω system) - prevents interference between active and inactive channels in multi-channel AFEs |
| 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) or industrial 5V/±5V rails |
Pinout & Package
MAX4559ESE is housed in a 16-pin narrow SO (Small Outline) package, 150 mil width, RoHS-compliant, with standard JEDEC MS-012AC footprint.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y₀ | Analog input for Y-multiplexer channel 0 - connects to source signal when Y-select = 00 |
| 2 | Y₁ | Analog input for Y-multiplexer channel 1 - selected when Y-select = 01 |
| 3 | Y | Y-multiplexer output - carries selected Y₀–Y₃ signal to downstream circuitry |
| 4 | X₀ | Analog input for X-multiplexer channel 0 - connects to source signal when X-select = 00 |
| 5 | X₁ | Analog input for X-multiplexer channel 1 - selected when X-select = 01 |
| 6 | ENABLE | Active-low global enable - drives all switches open (high-impedance) when logic high |
| 7 | VEE | Negative analog supply - sets lower rail for analog signal range; tied to GND for single-supply use |
| 8 | GND | Signal and digital ground reference - must be low-impedance return path for analog and logic currents |
| 9 | C | Address bit C - unused on MAX4559 (not connected; see truth table); reserved for family compatibility |
| 10 | B | Address bit B - selects upper bit of 2-bit address for both X and Y multiplexers |
| 11 | A | Address bit A - selects lower bit of 2-bit address; jointly controls X₀–X₃ and Y₀–Y₃ routing |
| 12 | X₂ | Analog input for X-multiplexer channel 2 - selected when X-select = 10 |
| 13 | X₃ | Analog input for X-multiplexer channel 3 - selected when X-select = 11 |
| 14 | X | X-multiplexer output - carries selected X₀–X₃ signal independently of Y path |
| 15 | Y₂ | Analog input for Y-multiplexer channel 2 - selected when Y-select = 10 |
| 16 | VCC | Positive analog/digital supply - powers internal switches and logic; defines upper analog rail |
Key Features
| Feature | Design Value |
|---|---|
| ±15kV HBM ESD protection on X/Y pins | Eliminates external protection components and enables direct connection to connectors or front-panel jacks in medical or test equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-to-1 analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG732BRUZ | 32-channel single-ended CMOS switch; 4.5Ω RON at +5V; no integrated ESD protection beyond 2kV HBM | Requires external ESD protection for field-deployed systems; better suited for PCB-internal routing than front-panel I/O | Select when higher channel count and lower RON are prioritized over integrated ESD robustness |
| TS5A3157DCUR | Single SPDT switch; 0.75Ω RON at +5V; ±6kV HBM ESD; no dual-bank architecture or address decoding | Cannot replace dual 4-to-1 functionality without discrete logic and multiple ICs; limited to simple on/off control | Select only for point-to-point switching where address-controlled multiplexing is unnecessary |
Compared with ADG732BRUZ and TS5A3157DCUR, the MAX4559ESE uniquely combines dual independent 4-to-1 routing, integrated ±15kV ESD protection, and guaranteed RON matching - making it the only drop-in solution for space-constrained, high-reliability multiplexing where board-level protection and channel coherence are mandatory.

FAQ
What is the maximum supply voltage range supported by the MAX4559ESE?
The MAX4559ESE supports dual supplies from ±2V to ±6V or a single supply from +2V to +12V. At ±5V, it guarantees 160Ω on-resistance and full rail-to-rail analog signal handling. Operation outside these ranges risks exceeding absolute maximum ratings and may cause permanent damage or undefined behavior.
Does the MAX4559ESE require external ESD protection components?
No - the MAX4559ESE integrates on-chip SCR-based ESD protection rated at ±15kV HBM, ±12kV IEC 1000-4-2 air-gap, and ±8kV contact discharge on all X and Y analog pins. This eliminates the need for external TVS diodes in most applications, provided system-level current limiting ensures SCR holding current (70mA at +85°C) is not exceeded.
Can the MAX4559ESE operate with a single 3.3V supply?
Yes - the MAX4559ESE is fully specified down to +2.7V single supply. At +3.3V, typical on-resistance is 400Ω, input logic thresholds are 0.5V (low) and 1.5V (high), and turn-on time is 350ns max. Performance remains functional but degrades versus ±5V operation, particularly in RON and speed.
How does the ENABLE pin function on the MAX4559ESE?
The ENABLE pin (Pin 6) is active-low: driving it logic high disconnects all analog paths (X₀–X₃, Y₀–Y₃) from their respective outputs (X, Y), placing them in high-impedance off-state. Driving it logic low enables normal address-controlled switching. It does not affect digital input thresholds or supply current consumption.
Is the MAX4559ESE pin-compatible with standard logic multiplexers like the 74HC4052?
Yes - the MAX4559ESE is explicitly designed as a pin-compatible upgrade to the 74HC4052, sharing identical pinout, supply pin locations (VCC, GND, VEE), and address/control assignments (A, B, ENABLE). However, it adds ±15kV ESD protection, lower leakage, and rail-to-rail analog capability not present in the HC4052.
