Product details
Overview
MAX4630EPD from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally closed (NC) 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 - ideal for battery-powered audio routing and automated test equipment relay replacement.
For engineers reviewing the MAX4630EPD datasheet, MAX4630EPD pinout, MAX4630EPD application, or MAX4630EPD equivalent, key selection criteria include ±15kV HBM ESD protection on NC/NO pins, guaranteed on-resistance matching (0.5Ω typ), -3dB bandwidth >300MHz, low THD (0.015%), and TTL/CMOS-compatible control logic across industrial temperature range (-40°C to +85°C).
Technical Context
The MAX4630EPD implements four independent NC SPST switches using CMOS architecture with integrated bidirectional SCRs on NC/NO terminals for ±15kV ESD protection per IEC 1000-4-2 air-gap and contact discharge standards. Each switch features rail-to-rail signal handling and bilateral conduction.
Control inputs accept TTL/CMOS logic levels (VIH = 2.4V min at 5V, VIH = 2.0V min at 3V); supply current remains ≤10µA over temperature. On-resistance flatness is 2Ω typ at 5V, ensuring minimal signal distortion across the full input voltage range (0V to V+).
Key Specifications

|---|---|
| Supply Voltage Range | +2V to +12V single supply - enables direct integration into 3.3V and 5V systems and extended battery-life designs. |
| On-Resistance (max) | 70Ω at V+ = 5V - ensures minimal insertion loss in audio and data-acquisition paths. |
| Off-Leakage Current | ±0.5nA at TA = +25°C - preserves signal integrity in high-impedance sample-and-hold circuits. |
| -3dB Bandwidth | >300MHz - supports video, RF sampling, and fast digital signal switching without attenuation. |
| ESD Protection | ±15kV HBM, ±15kV IEC 1000-4-2 air-gap, ±8kV contact - eliminates need for external TVS diodes on NC/NO lines. |
| Total Harmonic Distortion | 0.015% at 20Hz–20kHz - meets fidelity requirements for professional audio routing applications. |
| Turn-On/Off Time | 90ns/50ns typ at 5V - enables precise timing control in multiplexed data acquisition systems. |
Pinout & Package
MAX4630EPD is housed in a 14-pin plastic DIP package (PDIPN), through-hole mountable, rated for -40°C to +85°C operation. Pin pitch is 0.300", body width 0.330", compliant with JEDEC MS-001.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC1 | Analog terminal of Switch 1 - normally closed path; connects to COM1 when IN1 = HIGH. |
| 2 | COM1 | Common node of Switch 1 - bidirectional signal path shared between NC1 and (in other variants) NO1. |
| 3 | NO2 | Not connected on MAX4630EPD - this pin is NC2 on MAX4630; MAX4630 has no NO terminals. |
| 4 | COM2 | Common node of Switch 2 - routed to NC2 when IN2 = HIGH; isolated otherwise. |
| 5 | IN2 | Digital control input for Switch 2 - active-HIGH logic; drives internal CMOS gate. |
| 6 | IN3 | Digital control input for Switch 3 - compatible with 3.3V/5V TTL/CMOS logic families. |
| 7 | GND | Analog/digital ground reference - must be low-impedance connection for ESD current return path. |
| 8 | NC3 | Analog terminal of Switch 3 - normally closed; connects to COM3 when IN3 = HIGH. |
| 9 | COM3 | Common node of Switch 3 - carries full analog signal current up to ±10mA continuous. |
| 10 | COM4 | Common node of Switch 4 - shares same electrical specs as COM1–COM3; supports rail-to-rail swing. |
| 11 | NC4 | Analog terminal of Switch 4 - normally closed; latched only when IN4 = HIGH. |
| 12 | IN4 | Digital control input for Switch 4 - synchronized switching possible with all four INx pins. |
| 13 | IN1 | Digital control input for Switch 1 - controls NC1–COM1 path; VIH/VIL thresholds scale with V+. |
| 14 | V+ | Positive supply input - bypass with ≥0.1µF ceramic capacitor to GND for ESD transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| ±15kV ESD protection on NC/NO pins | Integrated bidirectional SCR clamps eliminate external protection components and prevent latchup under ESD stress. |
| Guaranteed on-resistance matching | 0.5Ω typical mismatch between channels at 5V - critical for precision multiplexer gain/phase tracking. |
| Rail-to-rail analog signal handling | Supports input/output voltages from GND to V+ - enables seamless interfacing with op-amps and ADCs without level-shifting. |
| Low THD and high bandwidth | 0.015% THD + noise and >300MHz -3dB bandwidth - preserves fidelity in audio, video, and high-speed data paths. |
| TTL/CMOS-compatible logic inputs | VIH = 2.4V (min) at 5V supply - ensures reliable interface with microcontrollers, FPGAs, and logic families without level translators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4630ESD | Same electrical specs; 14-pin SOIC package (surface-mount, 150mil width) | Preferred for space-constrained PCBs; requires reflow soldering and lacks DIP socket compatibility | Select MAX4630ESD for volume production where board area and assembly automation are priorities. |
| ADG1434BRUZ | Quad SPST, NC configuration; 4.5Ω max on-resistance at 5V (vs. 70Ω); ±30kV ESD rating; higher supply current (25µA) | Better suited for ultra-low-RON precision instrumentation; not pin-compatible; requires different layout | Choose ADG1434BRUZ only when on-resistance <5Ω is mandatory and board redesign is acceptable. |
Compared with MAX4630ESD, the MAX4630EPD offers identical analog performance but enables through-hole prototyping and legacy system upgrades; versus ADG1434BRUZ, it trades lower on-resistance for broader supply range (+2V to +12V), lower cost, and proven DIP reliability in field-deployed test gear.

FAQ
What is the maximum supply voltage rating for MAX4630EPD?
The MAX4630EPD 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; however, proper decoupling with a ≥0.1µF ceramic capacitor placed close to the V+ and GND pins is required to maintain stability and ESD immunity. Exceeding +13V risks permanent damage.
Does MAX4630EPD support rail-to-rail analog signals?
Yes, the MAX4630EPD supports rail-to-rail analog signal operation - meaning analog voltages applied to NC or COM pins can swing from GND to V+ without distortion or clipping. This is enabled by its CMOS process and internal level-shifting circuitry, making it suitable for interfacing directly with op-amps, ADCs, and DACs operating at the same supply rails.
How does the ESD protection work on MAX4630EPD's NC pins?
The MAX4630EPD integrates bidirectional silicon-controlled rectifiers (SCRs) between each NC pin and GND. During an ESD event (e.g., ±15kV HBM), the SCR triggers within nanoseconds, shunting surge current safely to ground. The device also includes series-limited diode clamps to V+ and GND for non-ESD overvoltage protection. Holding current is ~110mA at +25°C, so external current limiting below 35mA ensures automatic SCR reset after discharge.
Is MAX4630EPD pin-compatible with the 74HC4066?
Yes, the MAX4630EPD is explicitly designed as a pin-compatible, functionally enhanced replacement for the industry-standard 74HC4066. Its 14-pin DIP footprint matches exactly, and all NC/COM/IN/V+/GND assignments align. Unlike the 74HC4066, the MAX4630EPD adds ±15kV ESD protection, lower leakage (0.5nA vs. ~100nA), and guaranteed on-resistance specs - requiring no PCB changes for upgrade.
What is the typical on-resistance flatness of MAX4630EPD at 5V supply?
The typical on-resistance flatness of MAX4630EPD is 2Ω at V+ = 5V, defined as the difference between maximum and minimum RON measured across the full analog signal range (0V to V+). This tight flatness ensures minimal harmonic distortion and consistent gain across varying input signal amplitudes - a key advantage over standard analog switches with >10Ω flatness.
