Product details
Overview
MAX4620EPD+ from Maxim Integrated is a quad, normally open (NO), single-pole/single-throw (SPST) CMOS analog switch with ±15kV ESD protection on NO/NC pins, 70Ω max on-resistance at +5V, 0.5nA off-leakage at +25°C, and rail-to-rail signal handling - used in low-distortion audio routing and battery-powered test equipment where mechanical relay replacement is required.
For engineers reviewing the MAX4620EPD+ datasheet, MAX4620EPD+ pinout, MAX4620EPD+ application, or MAX4620EPD+ equivalent, key selection criteria include guaranteed on-resistance flatness (2Ω typ), TTL/CMOS-compatible control inputs, -40°C to +85°C operation, 14-pin DIP package compatibility, and ESD robustness for unshielded front-end signal paths.
Technical Context
The MAX4620EPD+ implements four independent bilateral SPST switches using CMOS process technology, each controlled by a dedicated TTL/CMOS-level digital input (IN1–IN4). Its internal SCR-based ESD protection activates within nanoseconds when NO/NC pins exceed supply rails, clamping ±15kV HBM transients without latchup.
It operates from a single +2V to +12V supply, supports rail-to-rail analog signals (0V to V+), and delivers <0.015% THD in 20Hz–20kHz audio paths. Switch timing is characterized across temperature and supply voltage, with tON/tOFF ≤180ns/100ns at +5V and +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 70Ω at +5V - ensures minimal signal attenuation and gain error in precision signal routing |
| Off-Leakage Current | ±0.5nA at +25°C - preserves accuracy in high-impedance sample-and-hold and sensor interfaces |
| ESD Protection | ±15kV HBM, ±15kV IEC 1000-4-2 air-gap - eliminates need for external TVS diodes on analog I/O lines |
| -3dB Bandwidth | >300MHz - supports video, RF sampling, and fast data-acquisition switching without roll-off |
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 9V battery systems |
| THD + Noise | 0.015% at 20Hz–20kHz - meets fidelity requirements for professional audio signal path switching |
| On-Resistance Matching | 0.5Ω typ between channels at +5V - critical for matched-gain multi-channel instrumentation |
Pinout & Package
MAX4620EPD+ is housed in a 14-pin plastic dual in-line package (PDIP) with 0.3-inch body width, through-hole mounting, and industry-standard pin spacing compatible with legacy prototyping and industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog switch terminals - connect only when corresponding INx is HIGH; isolated otherwise |
| 2, 4, 9, 10 | COM1–COM4 | Common analog node per switch - bidirectional signal path between COM and NO when enabled |
| 5–6, 12–13 | IN2–IN4, IN1 | TTL/CMOS digital control inputs - drive respective NO switch ON (HIGH) or OFF (LOW) |
| 7 | GND | Analog/digital ground reference - must be low-impedance return for leakage and ESD current paths |
| 14 | V+ | Positive supply input - powers internal logic and switch bias; bypass with 0.1µF ceramic capacitor near pin |
Key Features
| Feature | Design Value |
|---|---|
| Quad NO SPST topology | Four independent normally open switches - simplifies discrete relay replacement in automated test fixtures |
| Bilateral rail-to-rail switching | Supports analog signals from 0V to V+ in either direction - enables AC-coupled and DC-coupled signal routing |
| On-resistance flatness | 2Ω typ over full signal range at +5V - minimizes harmonic distortion and amplitude nonlinearity |
| ESD SCR holding current | 110mA typ at +25°C - defines maximum allowable source current to ensure automatic SCR turn-off post-ESD event |
| Charge injection | 5pC - limits voltage glitch on high-impedance nodes during switching, critical for precision sample-and-hold |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4620ESD+ | Same electrical specs, 14-pin SOIC package - 3.9mm width, surface-mount, higher density layout | Preferred for space-constrained PCBs; requires reflow assembly instead of through-hole | Select when board real estate is limited and SMT manufacturing is available |
| ADG1419BRUZ | Quad SPST NO, 0.6Ω on-resistance match, but only ±4.5kV ESD rating and 5.5V max supply | Suitable for low-voltage, low-noise lab instruments but not for field-deployed ESD-prone interfaces | Choose only if ESD immunity is secondary and ultra-low RON matching is primary requirement |
Compared with MAX4620ESD+, the MAX4620EPD+ offers identical analog performance but enables through-hole prototyping and legacy system upgrades; versus ADG1419BRUZ, it provides superior ESD resilience and wider supply range at the cost of slightly higher on-resistance.

FAQ
What is the maximum supply voltage for MAX4620EPD+?
The MAX4620EPD+ supports a single-supply operating range from +2V to +12V. Its absolute maximum rating is +13V referenced to GND. When operating near +12V, Maxim recommends bypassing V+ with a minimum 0.1µF ceramic capacitor placed as close as possible to the MAX4620EPD+ pin to suppress supply transients induced by ESD events or switching noise.
Does MAX4620EPD+ support rail-to-rail analog signals?
Yes, the MAX4620EPD+ supports rail-to-rail analog signal operation - meaning it can pass signals from 0V up to the positive supply voltage (V+) without clipping or distortion. This capability is intrinsic to its CMOS switch architecture and is specified across the full +2V to +12V supply range, making it suitable for both AC-coupled and DC-coupled signal paths in precision applications.
How does the ESD protection in MAX4620EPD+ work during a transient event?
The MAX4620EPD+ uses on-chip bidirectional silicon-controlled rectifiers (SCRs) between NO/NC pins and GND to clamp ±15kV ESD strikes. When a pin exceeds the supply rails, the SCR triggers in nanoseconds, diverting surge current safely to ground. The device also includes series-limited diodes to V+ for non-ESD overvoltage protection. Post-event, the SCR remains latched until current falls below ~110mA (typ), so external current limiting on connected sources is required for reliable recovery.
Can MAX4620EPD+ replace the 74HC4066 in existing designs?
Yes, the MAX4620EPD+ is explicitly designed as a pin-compatible replacement for the 74HC4066, sharing identical 14-pin DIP pinout and TTL/CMOS-compatible logic thresholds. It improves upon the 74HC4066 with ±15kV ESD protection, lower on-resistance (70Ω vs. typical 105Ω), tighter on-resistance matching (0.5Ω vs. >10Ω), and guaranteed operation down to +2V supply - enabling drop-in upgrades in legacy test and audio equipment.
What is the off-isolation performance of MAX4620EPD+ at 10MHz?
The MAX4620EPD+ delivers -45dB off-isolation at 10MHz (RL = 50Ω, CL = 5pF), as measured between the COM and NO terminals of a disabled switch. This level of isolation prevents crosstalk-induced errors in multi-channel data acquisition and RF signal routing applications. At 1MHz, off-isolation improves to -75dB, confirming strong channel separation across the audio and low-MHz frequency bands.
