Product details
Overview
The MAX4559EEE 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 used in audio/video switching, battery-powered instrumentation, and high-ESD industrial interfaces.
For engineers reviewing the MAX4559EEE datasheet, MAX4559EEE pinout, MAX4559EEE application, or MAX4559EEE equivalent, key selection considerations include its dual-channel 4:1 configuration, guaranteed RON match of 2Ω (typ), ±15kV ESD rating per IEC 1000-4-2, and compatibility with TTL/CMOS logic at +5V or ±5V supplies.
Technical Context
The MAX4559EEE implements two independent 4-to-1 analog multiplexers sharing common address lines (A, B) and enable control, with separate X and Y output paths. Each channel supports rail-to-rail analog signals and uses internal SCR-based ESD protection on all X/Y input/output pins - not diode clamps - enabling fast turn-on (<5ns) during ESD events and safe current shunting to GND.
Its digital interface accepts TTL/CMOS-compatible thresholds (+0.8V low / +2.4V high) under +5V or ±5V operation, while analog performance is defined by low charge injection (1pC typ), high off-isolation (-96dB at 100kHz), and minimal crosstalk (-93dB), making it suitable for precision signal routing where channel integrity and transient immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Configuration | Dual 4-to-1 multiplexer: two independent switch banks selecting one of four inputs each to dedicated X/Y outputs. |
| Supply Range | ±2V to ±6V dual supply or +2V to +12V single supply - enables operation in both bipolar and low-voltage unipolar systems. |
| On-Resistance (RON) | 160Ω typ at ±5V; ensures minimal signal attenuation and voltage drop in precision analog paths. |
| RON Match Between Channels | 2Ω typ - guarantees matched gain/attenuation across channels in differential or ratiometric applications. |
| ESD Protection | ±15kV HBM, ±12kV IEC air-gap, ±8kV IEC contact - protects against real-world handling and system-level ESD without latchup. |
| Off-Leakage Current | 1nA max at +25°C - preserves signal integrity in high-impedance sensor or reference circuits. |
| Switching Speed | tON = 150ns max, tOFF = 120ns max (RL = 300Ω, CL = 35pF) - supports audio and medium-speed data acquisition. |
Pinout & Package
MAX4559EEE is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.65mm pitch), rated for -40°C to +85°C operation and RoHS-compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | Y0–Y3 Inputs | Four analog inputs for second multiplexer bank; bidirectional, rail-to-rail capable. |
| 3 | Y Output | Common output node for Y-side 4:1 selection; connects to selected Y0–Y3 when enabled. |
| 6 | ENABLE | Active-low digital control: tie to GND to activate switches; drive high to force all channels OFF. |
| 7 | VEE | Negative analog supply input; connect to GND for single-supply operation (+2V to +12V). |
| 8 | GND | System ground reference for logic and analog sections; must be low-impedance for ESD current return. |
| 9, 10, 11 | A, B, C Address Inputs | Binary select lines (C unused on MAX4559); A/B determine which of four Y inputs is routed to Y output. |
| 12, 13, 14, 15 | X0–X3 Inputs | Four analog inputs for first multiplexer bank; electrically identical to Y0–Y3. |
| 16 | VCC | Positive analog/digital supply; powers internal logic translators and CMOS 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 |
|---|---|---|---|
| MAX4559CSE | Same functionality and pinout; rated for 0°C to +70°C only (vs. -40°C to +85°C for MAX4559EEE). | Suitable for commercial-grade consumer electronics but not extended-temperature industrial deployments. | Select MAX4559CSE only if ambient operating temperature remains within 0°C–70°C and cost is prioritized over ruggedness. |
| ADG408BRUZ | 8-channel single-ended 8:1 mux (not dual 4:1); 120Ω RON at ±15V; no integrated ±15kV ESD protection. | Requires external ESD protection and different address decoding; better suited for high-voltage (>±6V) applications. | Choose ADG408BRUZ only when higher supply voltage tolerance is required and board space allows for discrete ESD components. |
Compared with MAX4559CSE, the MAX4559EEE provides extended temperature operation and identical performance; versus ADG408BRUZ, it offers superior ESD immunity and dual-bank flexibility at the cost of lower maximum supply voltage.

FAQ
What is the maximum analog signal voltage range supported by the MAX4559EEE?
The MAX4559EEE supports rail-to-rail analog signals from VEE to VCC. With dual ±5V supplies, this means ±5V; with single +5V supply and VEE tied to GND, it handles 0V to +5V. Absolute maximum analog voltage is (VEE – 0.3V) to (VCC + 0.3V), per datasheet limits. The MAX4559EEE maintains low distortion and leakage across this full range.
Does the MAX4559EEE require external ESD protection components?
No, the MAX4559EEE integrates on-chip SCR-based ESD protection rated at ±15kV HBM, ±12kV IEC air-gap, and ±8kV IEC contact discharge on all X and Y pins. This eliminates the need for external TVS diodes or RC filters in most applications, provided system-level current limiting (below 70mA at +85°C) is maintained to ensure SCR turn-off after an event. The MAX4559EEE's architecture inherently avoids supply rail coupling during ESD strikes.
How does the ENABLE pin function on the MAX4559EEE?
The ENABLE pin (Pin 6) is active-low: tying it to GND enables both multiplexer banks, allowing address-controlled signal routing; driving it high (≥2.4V) forces all switches into the OFF state regardless of address inputs. This provides hardware-level channel disable capability for power sequencing, fault isolation, or safety interlocks. The MAX4559EEE draws <10µA at VEN = VCC, minimizing standby current impact.
Is the MAX4559EEE pin-compatible with standard logic-family multiplexers?
Yes, the MAX4559EEE is pin-compatible with the industry-standard 74HC4052 dual 4:1 analog multiplexer in the same 16-pin QSOP package. Pin assignments for VCC, GND, ENABLE, address lines (A, B), and X/Y signal terminals match directly, enabling drop-in replacement without PCB modification. The MAX4559EEE improves upon the 74HC4052 with ±15kV ESD protection, lower RON, and guaranteed performance over -40°C to +85°C.
What is the typical on-resistance matching between channels in the MAX4559EEE?
The MAX4559EEE guarantees on-resistance matching (ΔRON) of ≤6Ω maximum across channels at +25°C, with a typical value of 2Ω. This tight matching ensures consistent gain, attenuation, and settling behavior when routing signals through different paths - critical for ratiometric measurements, differential signaling, or calibration routines. The MAX4559EEE achieves this via matched transistor geometry and on-die trimming, validated across its full operating temperature range.
