Product details
Overview
MAX4559CPE 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 on-resistance at ±5V supply, and rail-to-rail analog signal handling up to ±6V. It operates across 0°C to +70°C and is used in audio/video switching, battery-powered instrumentation, and high-ESD industrial interfaces.
For engineers reviewing the MAX4559CPE datasheet, MAX4559CPE pinout, MAX4559CPE application, or MAX4559CPE equivalent, key selection criteria include guaranteed RON match (2Ω typ), <−93dB crosstalk at 100kHz, 1nA off-leakage at +25°C, and compatibility with TTL/CMOS logic under +5V or ±5V supplies.
Technical Context
The MAX4559CPE implements two independent 4-to-1 analog multiplexers sharing common address lines (A, B) and enable control, with separate X and Y output buses. Each channel uses complementary CMOS switch architecture with integrated SCR-based ESD protection on all analog I/O pins (X₀–X₃, Y₀–Y₃, X, Y).
It supports single-supply operation from +2V to +12V or dual supplies from ±2V to ±6V, with digital inputs referenced to VCC/GND and analog paths referenced to VCC/VEE. Break-before-make timing is guaranteed at 4ns min, and charge injection is limited to 2.4pC (±5V) or 1pC (+5V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual 4-to-1 analog multiplexer with shared address/control |
| On-Resistance (±5V) | 160Ω max - ensures minimal signal attenuation and gain error in precision sensor or audio paths |
| RON Match | 2Ω typical - enables accurate ratiometric measurements and matched channel performance |
| Off-Leakage Current | 1nA at +25°C - preserves signal integrity in high-impedance, low-power sampling circuits |
| Crosstalk | <−93dB at 100kHz - prevents interference between active and inactive channels in multi-signal systems |
| ESD Protection | ±15kV HBM, ±12kV IEC air-gap, ±8kV IEC contact - eliminates need for external TVS diodes in portable/harsh environments |
| Supply Range | Single: +2V to +12V; Dual: ±2V to ±6V - supports wide input voltage flexibility including Li-ion and industrial rails |
Pinout & Package
MAX4559CPE is housed in a 16-pin plastic DIP package (0.300" width), compatible with through-hole prototyping and legacy industrial PCBs. Pin assignments are validated per Maxim/Analog Devices datasheet Rev 1 (2/21).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5 | Y₀, Y₁, Y₂, Y₃ | Analog inputs for Y-side multiplexer - bidirectional, rail-to-rail capable |
| 3 | Y | Common output for Y-side multiplexer - connects selected Yn channel |
| 6 | ENABLE | Active-low digital enable - drives all switches open when high; ties to GND for operation |
| 7 | VEE | Negative analog supply - grounded for single-supply use; sets lower analog rail |
| 8 | GND | Logic and analog reference ground - must be low-impedance return path |
| 9, 10, 11 | C, B, A | Digital address inputs - encode 4-channel selection (C unused on MAX4559) |
| 12–15 | X₀, X₁, X₂, X₃ | Analog inputs for X-side multiplexer - electrically identical to Y-side inputs |
| 16 | VCC | Positive analog/digital supply - powers internal logic and switch drivers |

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-channel single-ended mux; higher RON (100Ω typ @ +5V); no integrated ESD protection | Requires external TVS diodes; better suited for low-noise lab equipment than portable/harsh environments | Select when higher channel count is needed and board space allows for discrete ESD protection |
| TMUX1308PWR | 8-channel mux with 1.8V–5.5V supply; 4.5Ω RON match; ±2kV HBM only | Lacks system-level ESD robustness; optimized for low-voltage MCU interfacing, not industrial handling | Prefer for cost-sensitive consumer electronics where external ESD is already implemented |
Compared with ADG408BRZ and TMUX1308PWR, the MAX4559CPE uniquely delivers integrated ±15kV ESD protection, dual independent 4:1 routing, and sub-2Ω RON matching-making it optimal for ruggedized, space-constrained, and precision analog signal routing where reliability and channel consistency are critical.

FAQ
What is the maximum supply voltage range supported by the MAX4559CPE?
The MAX4559CPE supports dual supplies from ±2V to ±6V or a single supply from +2V to +12V. Operation outside these ranges risks permanent damage. At ±5V, on-resistance is guaranteed at 160Ω max; at +5V single supply, it is 220Ω max. The device's internal ESD diodes clamp signals exceeding VCC or VEE, but sustained overvoltage must be avoided per Absolute Maximum Ratings.
Does the MAX4559CPE require external ESD protection components?
No, the MAX4559CPE does not require external ESD protection components. It integrates on-chip SCR-based protection rated for ±15kV HBM, ±12kV IEC air-gap, and ±8kV IEC contact discharge on all analog I/O pins (X₀–X₃, Y₀–Y₃, X, Y). This eliminates the need for discrete TVS diodes in most end-equipment designs, reducing BOM count and PCB area while maintaining system-level robustness.
How does the ENABLE pin function on the MAX4559CPE?
The ENABLE pin (Pin 6) is an active-low digital control input. When pulled high (to VCC), all analog switches are forced open (high-impedance state), regardless of address inputs. When tied to GND, the device is enabled and responds to A/B address signals to route the selected Xn and Yn inputs to their respective outputs. No pull-up or pull-down resistors are required-direct connection suffices.
Can the MAX4559CPE handle bidirectional analog signals?
Yes, the MAX4559CPE supports fully bidirectional analog signal flow. Its CMOS switch architecture has no inherent directionality: X₀–X₃ and Y₀–Y₃ pins are interchangeable as inputs or outputs, and signals pass with equal fidelity in either direction. This enables flexible use cases such as shared bus arbitration, loopback testing, and reconfigurable signal paths without redesigning the analog front-end.
What is the guaranteed on-resistance match between channels for the MAX4559CPE?
The MAX4559CPE guarantees a maximum on-resistance match (ΔRON) of 6Ω over temperature (0°C to +70°C) and 8Ω across the full operating range, with a typical value of 2Ω at +25°C. This tight matching ensures consistent gain and minimal channel-to-channel error in applications like ratiometric sensor reading, programmable gain amplifiers, and calibrated test equipment where relative accuracy matters more than absolute RON.
