Analog Devices Inc./Maxim Integrated MAX4559ESE+T

Overview

The MAX4559ESE+T 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 MAX4559ESE+T datasheet, MAX4559ESE+T pinout, MAX4559ESE+T application, or MAX4559ESE+T equivalent, key selection criteria include guaranteed R_ON match (2Ω typ), sub-1nA off-leakage at +25°C, TTL/CMOS-compatible digital inputs, and verified break-before-make timing (4–15ns) under dual-supply operation.

Technical Context

The MAX4559ESE+T implements two independent 4-to-1 multiplexers sharing common address lines (A, B) and enable control, with separate X and Y analog output buses. Each channel uses complementary CMOS switch pairs with integrated SCR-based ESD protection on all X/Y input/output terminals.

Its logic interface operates with fixed +0.8V/+2.4V thresholds across supply ranges, enabling direct interfacing with +5V or ±5V digital controllers without level shifting. Signal path performance is characterized by <0.02% THD into 600Ω and -93dB crosstalk in 50Ω systems at 100kHz.

FAQ

What supply voltage ranges does the MAX4559ESE+T support?

The MAX4559ESE+T supports dual supplies from ±2V to ±6V and single supplies from +2V to +12V. This flexibility allows direct integration into both bipolar sensor front-ends and unipolar microcontroller-based systems. The device maintains rail-to-rail analog signal handling across all supported supply configurations, and its digital inputs remain TTL/CMOS-compatible at +5V or ±5V without level-shifting circuitry. The MAX4559ESE+T datasheet specifies absolute maximum ratings up to ±13V on VCC/VEE.

Does the MAX4559ESE+T require external ESD protection components?

No, the MAX4559ESE+T does not require external ESD protection components on its X and Y signal pins. It integrates on-chip SCR-based protection rated for ±15kV per Human Body Model, ±12kV per IEC 1000-4-2 air-gap discharge, and ±8kV per IEC 1000-4-2 contact discharge. This eliminates the need for discrete TVS diodes or RC filters in most end-equipment designs, reducing BOM count and PCB area. The MAX4559ESE+T's internal protection architecture safely shunts ESD current to ground within nanoseconds while maintaining signal integrity during normal operation.

What is the on-resistance matching specification for the MAX4559ESE+T?

The MAX4559ESE+T guarantees on-resistance matching of 2Ω (typical) between channels under ±5V supply conditions, with a maximum of 6Ω over temperature and process variation. This tight matching is critical for applications requiring balanced gain or attenuation across multiple signal paths - such as differential sensor interfaces or multi-channel audio mixing. The MAX4559ESE+T achieves this via matched transistor sizing and layout symmetry in its CMOS switch array, and the specification is production-tested per datasheet revision 1.

Can the MAX4559ESE+T operate with a +3.3V single supply?

Yes, the MAX4559ESE+T is fully specified for +3.3V single-supply operation. At VCC = +3.3V, it delivers 400Ω typical on-resistance, 1.5ns typical break-before-make delay, and 0.5pC typical charge injection - all while maintaining 1nA off-leakage at +25°C. Its logic inputs accept +0.5V low and +1.5V high thresholds at this supply, ensuring compatibility with 3.3V LVTTL and LVCMOS controllers. The MAX4559ESE+T's electrical characteristics table explicitly includes +3V supply data, confirming functional operation down to +2.7V.

How does the ENABLE pin function on the MAX4559ESE+T?

The ENABLE pin (Pin 6) on the MAX4559ESE+T is an active-low digital control that globally disables all analog switches when driven high (≥2.4V). When pulled low (≤0.8V) or tied to GND, the device responds to address inputs A and B to route selected channels. During disable, all switch paths exhibit high off-isolation (>−96dB) and minimal leakage (<10nA at +85°C). The MAX4559ESE+T's ENABLE function is internally buffered and draws less than 1µA, making it suitable for low-power state management in battery-operated systems.
