Product details
Overview
The MAX4620ESD+ from Maxim Integrated is a low-voltage, ±15kV ESD-protected, quad single-pole/single-throw (SPST) analog switch with four normally open (NO) channels, 70Ω max on-resistance at +5V, 0.5nA off-leakage at +25°C, and rail-to-rail signal handling - designed for precision audio routing and battery-powered test equipment where mechanical relay replacement is required.
For engineers reviewing the MAX4620ESD+ datasheet, MAX4620ESD+ pinout, MAX4620ESD+ application, or MAX4620ESD+ equivalent, key selection criteria include guaranteed on-resistance flatness (2Ω typ), TTL/CMOS-compatible control inputs, ±15kV HBM ESD protection on NO pins, and SO-14 package compatibility with legacy 74HC4066 layouts.
Technical Context
The MAX4620ESD+ implements CMOS-based SPST switches with integrated bidirectional SCR structures on NO terminals for ±15kV ESD protection per IEC 1000-4-2 air-gap and contact discharge standards. Each channel operates independently with TTL/CMOS logic thresholds (VIH = 2.4V, VIL = 0.8V at +5V).
It supports single-supply operation from +2V to +12V, delivers >300MHz -3dB bandwidth, and maintains on-resistance matching of 0.5Ω (typ) between channels at +5V - enabling low-distortion (<0.015% THD), low-crosstalk (-90dB at 1MHz), and fast switching (tON = 150ns typ at +5V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 70Ω at +5V supply - ensures minimal signal attenuation in audio and data-acquisition paths |
| Off-Leakage Current | ±0.5nA at TA = +25°C - preserves accuracy in high-impedance sample-and-hold circuits |
| ESD Protection | ±15kV HBM, ±15kV IEC 1000-4-2 air-gap, ±8kV contact - eliminates need for external TVS on NO pins |
| Rail-to-Rail Signal Range | 0V to V+ - enables full-swing analog signal switching without clipping |
| -3dB Bandwidth | >300MHz - supports high-speed video and communications signal routing |
| Total Harmonic Distortion | 0.015% at 20Hz–20kHz - meets fidelity requirements for professional audio applications |
| Supply Voltage Range | +2V to +12V single supply - compatible with Li-ion, 3.3V, and 5V systems |
Pinout & Package
MAX4620ESD+ is housed in a 14-pin SO (Small Outline) package with standard 1.27mm pitch, JEDEC MS-012AC compliant footprint, and exposed pad not present. Pin assignments are identical across MAX4620/MAX4630/MAX4640 families in same package variant.

| 7 | GND | Analog/digital ground reference - must be low-impedance return for leakage and ESD current |
| 8 | NO3 | Analog output terminal for Switch 3 - normally open; connects to COM3 when IN3 = HIGH |
| 9 | COM3 | Common analog node for Switch 3 - shared path for NO3 and NC3 (not used in MAX4620) |
| 10 | COM4 | Common analog node for Switch 4 - completes fourth SPST NO path |
| 11 | NO4 | Analog output terminal for Switch 4 - normally open; connects to COM4 when IN4 = HIGH |
| 12 | IN4 | Digital control input for Switch 4 - enables precise sequencing of all four switches |
| 13 | IN1 | Digital control input for Switch 1 - primary enable for first channel; VIH = 2.4V min at +5V |
| 14 | V+ | Positive supply input - powers internal CMOS switches and ESD protection SCRs; bypass with 0.1µF |
Key Features

FAQ
What is the maximum supply voltage rating for the MAX4620ESD+?
The MAX4620ESD+ has an absolute maximum supply voltage (V+ to GND) of +13V, but its specified operating range is +2V to +12V. Operation at +12V is fully characterized and supported with proper 0.1µF local bypassing. Exceeding +13V risks permanent damage per Absolute Maximum Ratings.
Does the MAX4620ESD+ support rail-to-rail analog signal switching?
Yes, the MAX4620ESD+ supports true rail-to-rail analog signal switching - its input voltage range on COM, NO, and NC pins extends from 0V to V+ across the full temperature range. This allows undistorted passage of signals spanning the entire supply rail, essential for audio and precision measurement applications.
How does the ESD protection in the MAX4620ESD+ work without external components?
The MAX4620ESD+ integrates bidirectional silicon-controlled rectifiers (SCRs) directly on-chip between NO/NC pins and GND. During an ESD event, these SCRs trigger within nanoseconds to shunt ±15kV HBM or IEC 1000-4-2 surge current safely to ground - eliminating need for external TVS diodes or RC networks on analog signal paths.
Is the MAX4620ESD+ pin-compatible with the 74HC4066?
Yes, the MAX4620ESD+ is explicitly designed as a pin-compatible replacement for the industry-standard 74HC4066 in SO-14 packaging. Pin functions, spacing, and logic thresholds match - enabling direct substitution without PCB modification or firmware changes in existing designs.
What is the typical on-resistance matching between channels in the MAX4620ESD+?
The MAX4620ESD+ guarantees on-resistance matching of 0.5Ω (typical) between any two channels at +5V and +25°C, with a maximum mismatch of 3Ω over temperature. This tight matching ensures consistent gain and phase response across multiplexed signal paths in instrumentation and audio applications.
