Product details
Overview
MAX4559CEE+ 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 switch pins, 160Ω typical on-resistance at ±5V supply, < −93dB crosstalk at 100kHz, and rail-to-rail analog signal handling. It serves as a precision signal selector in battery-powered audio/video routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4559CEE+ datasheet, MAX4559CEE+ pinout, MAX4559CEE+ application, or MAX4559CEE+ equivalent, key selection criteria include guaranteed RON match (2Ω typ), sub-1nA off-leakage at +25°C, TTL/CMOS-compatible logic thresholds (+0.8V to +2.4V), and dual ±2V to ±6V or single +2V to +12V supply flexibility.
Technical Context
The MAX4559CEE+ implements two independent 4-to-1 analog multiplexers sharing common address lines (A, B) and enable control, with separate X and Y output terminals. Each channel uses complementary CMOS switch architecture with integrated ESD protection SCRs tied to GND on all X/Y pins and their complements.
Its switching behavior is governed by break-before-make timing (4–15ns), charge injection of 2.4pC (±5V), and analog signal range spanning VEE to VCC, supporting true bidirectional signal flow without polarity constraints. Logic-level translation ensures compatibility across single +5V and dual ±5V supply configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.

FAQ
What supply voltage ranges does the MAX4559CEE+ support?
The MAX4559CEE+ operates from dual supplies of ±2V to ±6V or a single supply of +2V to +12V. At ±5V, it achieves 160Ω typical on-resistance and full rail-to-rail analog signal handling. The device maintains TTL/CMOS logic compatibility across this range, with input thresholds scaling from +0.8V/+2.4V at +5V to ~+3.1V at +12V. This flexibility allows direct use in both legacy ±5V systems and modern low-voltage battery-powered designs without level-shifting circuitry.
How does the ESD protection on the MAX4559CEE+ work without affecting normal operation?
The MAX4559CEE+ integrates on-chip bidirectional SCRs between each protected X/Y pin and GND. These SCRs remain off during normal operation, drawing negligible current and introducing no measurable impact on RON, leakage, or bandwidth. During an ESD event, the SCR triggers in nanoseconds, shunting surge current safely to ground. Holding current (110mA/95mA at +25°C) ensures latching until external current drops below threshold - a design feature requiring current-limiting external sources to guarantee automatic recovery after ESD exposure.
Can the MAX4559CEE+ be used with single-ended or differential signals?
Yes, the MAX4559CEE+ supports both single-ended and differential signal routing due to its fully bidirectional analog switch architecture and rail-to-rail capability. Signals pass equally well in either direction across X0–X3→X and Y0–Y3→Y paths. Its matched RON (2Ω typ) and low crosstalk (<−93dB) make it suitable for differential pairs where channel tracking matters - though for dedicated differential switching, purpose-built differential multiplexers may offer tighter skew control. No polarity restrictions apply to input/output assignment.
What is the maximum analog signal frequency supported by the MAX4559CEE+?
The MAX4559CEE+ maintains flat insertion loss up to ~50MHz in 50Ω systems, with −3dB bandwidth exceeding 100MHz. However, off-isolation degrades above 1MHz (−68dB at 1MHz, worsening ~20dB/decade), limiting high-frequency rejection. For audio and DC–20kHz sensor applications, THD remains <0.02% into 600Ω loads. In RF or high-speed digital contexts, layout-dependent parasitics dominate performance - the device is optimized for precision analog multiplexing, not GHz signal switching.
Is the MAX4559CEE+ pin-compatible with standard logic multiplexers like the 74HC4052?
Yes, the MAX4559CEE+ is explicitly designed as a pin-compatible upgrade to the 74HC4052 in 16-pin QSOP packages. It shares identical pin assignments for VCC, GND, ENABLE, A/B address lines, and X/Y analog I/O terminals. Unlike the 74HC4052, the MAX4559CEE+ adds ±15kV HBM ESD protection, lower on-resistance (160Ω vs. ~120Ω typical but unguaranteed), guaranteed RON matching, and rail-to-rail operation - enabling drop-in replacement where enhanced robustness and precision are required.
