Product details
Overview
MAX4576EUA+ from Maxim Integrated is a dual normally closed (NC) SPST CMOS analog switch optimized for low-voltage, high-ESD-sensitivity signal routing. It operates from +2V to +12V single supply, delivers 70Ω max on-resistance at +5V, 0.5nA off-leakage at +25°C, and supports rail-to-rail analog signals up to 300MHz bandwidth - ideal for battery-powered audio switching and automated test equipment relay replacement.
For engineers reviewing the MAX4576EUA+ datasheet, MAX4576EUA+ pinout, MAX4576EUA+ application, or MAX4576EUA+ equivalent, key selection criteria include ±15kV HBM ESD protection on NC pins, guaranteed on-resistance matching (0.5Ω typ), low THD (0.015%), and µMAX-8 package compatibility with space-constrained portable designs.
Technical Context
The MAX4576EUA+ implements two independent, TTL/CMOS-compatible, bilateral SPST switches configured as normally closed (NC), each with integrated bidirectional SCR-based ±15kV IEC 1000-4-2 ESD protection on NC terminals. Its CMOS architecture enables rail-to-rail signal handling without level-shifting circuitry.
On-resistance flatness is specified at 2Ω (typ) over the full signal range at +5V, and on-resistance matching between channels is tightly controlled at 0.5Ω (typ), enabling precision signal path balancing in dual-channel instrumentation and audio routing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply - supports direct integration into Li-ion, 3.3V, and 5V systems without level shifters. |
| On-Resistance (max) | 70Ω at +5V - ensures minimal insertion loss and voltage drop in low-level analog signal paths. |
| Off-Leakage Current | 0.5nA at +25°C - preserves signal integrity in high-impedance sample-and-hold and sensor front-end circuits. |
| -3dB Bandwidth | >300MHz - enables clean switching of video, RF control, and fast data-acquisition signals. |
| ESD Protection | ±15kV HBM, ±15kV IEC 1000-4-2 air-gap, ±8kV contact - eliminates need for external TVS diodes on NC pins. |
| Total Harmonic Distortion | 0.015% - meets fidelity requirements for professional audio routing and measurement-grade signal paths. |
| Turn-On/Off Time | 90ns/50ns (typ) at +5V - supports high-speed multiplexing in automated test and communications switching. |
Pinout & Package
MAX4576EUA+ is housed in an 8-pin µMAX package (3mm × 3mm, 0.5mm pitch), thermally enhanced for compact portable and battery-powered PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC1 | Normally closed analog terminal for Switch 1 - connects to COM1 when IN1 = logic low. |
| 2 | COM1 | Common analog node for Switch 1 - bidirectional signal path shared with NC1 and NO1 (not used in MAX4576). |
| 3 | IN2 | Digital control input for Switch 2 - TTL/CMOS-compatible; drives internal gate to open/close NC2. |
| 4 | GND | Analog/digital ground reference - must be low-impedance return for ESD current and signal integrity. |
| 5 | NC2 | Normally closed analog terminal for Switch 2 - connects to COM2 when IN2 = logic low. |
| 6 | COM2 | Common analog node for Switch 2 - primary signal path for second NC switch channel. |
| 7 | IN1 | Digital control input for Switch 1 - independent logic control enables asynchronous dual-channel switching. |
| 8 | V+ | Positive supply input - bypass with 0.1µF ceramic capacitor near pin to stabilize during ESD transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional SCR ESD protection | ±15kV HBM and IEC 1000-4-2 on NC pins - safely shunts ESD energy to GND without latch-up or damage. |

| Rail-to-rail signal handling | Full V+ to GND analog range supported - eliminates clipping in audio, sensor, and DAC output switching. |
| Low distortion & high bandwidth | 0.015% THD and >300MHz -3dB bandwidth - preserves waveform fidelity in audio, video, and high-speed data routing. |
| Ultra-low power operation | 1µA typical supply current - extends battery life in portable medical, handheld test, and IoT edge devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4542EUA+ | Pin-compatible but NC/NO configuration differs: MAX4542 has one NC + one NO switch; MAX4576 has two NC switches. | Not suitable for dual-NC-only topologies; requires redesign if both paths must close simultaneously on logic low. | Select MAX4542EUA+ only when mixed NC/NO functionality is required and board layout allows reassignment of signal routing. |
| ADG774ARUZ | Higher on-resistance (1.8Ω typ at +3V), no integrated ±15kV ESD protection - requires external TVS diodes on analog lines. | Less robust in unshielded or user-accessible interfaces; higher RON limits use in low-voltage precision signal chains. | Choose ADG774ARUZ only when ESD stress is controlled and on-resistance sensitivity is secondary to cost or availability. |
Compared with MAX4542EUA+ and ADG774ARUZ, the MAX4576EUA+ uniquely delivers dual NC topology with guaranteed ±15kV ESD hardening and 70Ω max RON, making it the only option for compact, high-reliability, low-voltage NC-switching where pinout and ESD resilience are non-negotiable.

FAQ
What is the maximum supply voltage rating for MAX4576EUA+?
The MAX4576EUA+ has an absolute maximum supply voltage (V+ to GND) of +13V, with recommended operating range from +2V to +12V. Operation at +12V is supported with proper 0.1µF local bypassing; exceeding +13V risks permanent damage per Absolute Maximum Ratings.
Does MAX4576EUA+ support rail-to-rail analog signal switching?
Yes, MAX4576EUA+ fully supports rail-to-rail analog signal switching - its CMOS architecture allows input signals from GND to V+ without clipping or distortion, verified across the full -40°C to +85°C temperature range and at supply voltages down to +2V.
How does the ±15kV ESD protection work on MAX4576EUA+ NC pins?
MAX4576EUA+ integrates bidirectional SCRs between each NC pin and GND. During an ESD event, the SCR triggers within nanoseconds, clamping the voltage and diverting current safely to ground. The device specifies 110mA holding current, requiring external current limiting below 70mA at +85°C to ensure automatic turn-off.
What is the on-resistance matching specification for MAX4576EUA+?
MAX4576EUA+ guarantees on-resistance matching (∆RON) of 0.5Ω (typical) and 3Ω (max) between its two NC switches at +5V and +25°C. This tight matching ensures balanced signal paths in differential or dual-channel applications such as stereo audio routing or dual-sensor multiplexing.
Is MAX4576EUA+ pin-compatible with other devices in the MAX457x family?
Yes, MAX4576EUA+ shares identical pinout and package with MAX4575EUA+ and MAX4577EUA+ in the µMAX-8 format. However, internal switch configuration differs: MAX4576 provides two NC switches, while MAX4575 offers two NO and MAX4577 offers one NO + one NC - functional substitution requires verification of logic polarity and signal path topology.
