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.
For engineers reviewing the MAX4620EPD datasheet, MAX4620EPD pinout, MAX4620EPD application, or MAX4620EPD equivalent, key selection considerations 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 signal interfaces.
Technical Context
The MAX4620EPD implements four independent bilateral SPST switches using CMOS architecture, each controlled by a dedicated TTL/CMOS-level digital input (IN1–IN4). Its internal SCR-based ESD protection activates within nanoseconds during ±15kV air-gap or contact discharge events, clamping NO/NC pins to ground without latchup.
It operates from a single +2V to +12V supply, supports rail-to-rail analog signals (0V to V+), and delivers guaranteed on-resistance matching (0.5Ω typ at +5V) and flatness (2Ω typ) across the full signal range - enabling precision multiplexing in data-acquisition and sample-and-hold circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 70Ω at +5V supply - ensures minimal voltage drop and signal attenuation in low-level analog paths |
| Off-Leakage Current | 0.5nA at TA = +25°C - preserves accuracy in high-impedance sample-and-hold and sensor front-ends |
| ESD Protection | ±15kV HBM, ±15kV IEC 1000-4-2 air-gap - eliminates need for external TVS diodes on signal lines |
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 9V battery systems |
| -3dB Bandwidth | >300MHz - supports high-fidelity video and RF signal switching without roll-off |
| Total Harmonic Distortion | 0.015% - maintains fidelity in audio-grade signal routing applications |
| Turn-On/Off Time | 90ns/50ns typical at +5V - suitable for fast-sampling data acquisition and digital waveform generation |
Pinout & Package
MAX4620EPD is housed in a 14-pin plastic dual in-line package (PDIP), with 0.300-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 - carries bidirectional rail-to-rail signals when switch is ON |
| 5–6, 12–13 | IN2–IN4, IN1 | TTL/CMOS-compatible digital control inputs - drive respective NOx switch ON/OFF with <0.8V/ >2.4V thresholds |
| 7 | GND | Analog/digital reference ground - must be low-impedance return path for ESD current and signal integrity |
| 14 | V+ | Positive supply input - powers internal logic and switch core; requires local 0.1µF bypass to GND |
Key Features
| Feature | Design Value |
|---|---|
| Quad NO SPST topology | Four independent normally open switches - simplifies discrete relay replacement and avoids NC cross-talk in signal routing |
| Bilateral rail-to-rail switching | Supports analog signals from 0V to V+ in either direction - enables use in AC-coupled audio and bidirectional sensor interfaces |
| On-resistance matching | 0.5Ω typical mismatch between channels at +5V - critical for matched-gain instrumentation multiplexers |
| ESD SCR holding current | 110mA typical at +25°C - defines minimum external current limiting required to ensure automatic SCR turn-off post-ESD event |
| Charge injection | 5pC typical - limits voltage glitch in sample-and-hold capacitors, preserving DC accuracy |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4610EPA | Single SPST NO switch, same 14-pin PDIP package, identical ESD rating and on-resistance spec, but only one channel | Suitable for point-to-point switching where quad density is unnecessary; higher per-channel cost in multi-channel systems | Select when board space allows discrete channel placement and design requires independent thermal or layout isolation per switch |
| ADG1419BRUZ | Quad SPST NO switch in 16-pin TSSOP; lower on-resistance (4.7Ω typ), higher supply limit (+36V), but no integrated ±15kV ESD protection | Requires external ESD protection for exposed interfaces; better suited for industrial PLC I/O modules than consumer handhelds | Choose for high-voltage signal routing where ESD risk is mitigated by enclosure design, not component-level hardening |
Compared with MAX4610EPA and ADG1419BRUZ, the MAX4620EPD uniquely combines quad-channel density, ±15kV on-die ESD protection, and 14-pin DIP packaging - making it optimal for space-constrained, user-accessible, battery-operated systems requiring field-replaceable analog routing.

FAQ
What is the maximum supply voltage rating for MAX4620EPD?
The MAX4620EPD has an absolute maximum supply voltage (V+ to GND) of +13V, with guaranteed functional operation from +2V to +12V. Operation near +12V requires a minimum 0.1µF ceramic bypass capacitor placed directly between V+ and GND at the device pins to suppress supply transients induced by ESD events or fast switching.
Does MAX4620EPD support rail-to-rail analog signal switching?
Yes, the MAX4620EPD supports true rail-to-rail analog signal switching - its COM, NO, and NC terminals handle voltages from 0V to V+ continuously. This capability is enabled by its CMOS process and internal level-shifting circuitry, allowing undistorted passage of AC-coupled audio, sensor outputs, and other full-supply-range signals without clipping.
How does the ESD protection in MAX4620EPD behave after a ±15kV strike?
After a ±15kV ESD event, the on-chip SCR latches ON and remains conducting until the current through the NO or NC pin falls below its holding current (110mA typ at +25°C). To ensure automatic recovery, external circuitry must limit current into those pins to ≤35mA - especially critical at +85°C where holding current drops to 70mA - so the SCR turns off once the ESD pulse ends.
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 logic compatibility. However, it adds ±15kV ESD protection, lower on-resistance (70Ω vs. ~120Ω), and guaranteed leakage specs - requiring no PCB changes but delivering improved robustness and performance.
What is the typical on-resistance flatness of MAX4620EPD at +5V?
The typical on-resistance flatness of MAX4620EPD at +5V is 2Ω - defined as the difference between maximum and minimum RON measured across the full 0V to +5V analog signal range. This tight flatness ensures consistent gain and minimal harmonic distortion in variable-amplitude signal paths such as audio volume control or programmable gain stages.
