Product details
Overview
The MAX4620EUD+ from Maxim Integrated is a low-voltage, quad single-pole/single-throw (SPST) analog switch with four normally open (NO) channels, ±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-designed for audio routing and battery-powered test equipment where mechanical relay replacement is required.
For engineers reviewing the MAX4620EUD+ datasheet, MAX4620EUD+ pinout, MAX4620EUD+ application, or MAX4620EUD+ equivalent, key selection criteria include guaranteed on-resistance flatness (2Ω typ), TTL/CMOS-compatible control inputs, -40°C to +85°C operation in 14-pin TSSOP, and ESD robustness per IEC 1000-4-2 air-gap and contact discharge standards.
Technical Context
The MAX4620EUD+ implements CMOS-based SPST switches with integrated bidirectional SCRs on NO/NC terminals for ±15kV HBM and IEC 1000-4-2 ESD protection. Each channel operates independently with TTL/CMOS-level digital inputs and supports rail-to-rail analog signals from 0V to V+ (2V–12V).
Its architecture guarantees on-resistance matching ≤0.5Ω (typ) and flatness ≤2Ω (typ) over the full signal range at +5V, while maintaining 0.5nA leakage at +25°C and <10µA supply current-enabling low-power, low-distortion (<0.015% THD) signal switching in space-constrained portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 70Ω at +5V - ensures minimal voltage drop and power loss in signal paths up to ±10mA continuous current. |
| Off-Leakage Current | ±0.5nA at +25°C - preserves signal integrity in high-impedance sample-and-hold or sensor interfaces. |
| ESD Protection | ±15kV HBM, ±15kV IEC 1000-4-2 air-gap, ±8kV contact - eliminates need for external TVS diodes in handheld or exposed I/O designs. |
| Supply Range | +2V to +12V single supply - supports direct integration into 3.3V, 5V, and 9V battery-powered systems without level-shifting. |
| Bandwidth (-3dB) | >300MHz - enables clean switching of video, RF sampling, and high-speed data-acquisition signals. |
| THD + Noise | 0.015% at 20Hz–20kHz - meets fidelity requirements for professional audio routing and instrumentation-grade signal chains. |
| Turn-On/Off Time | 90ns/50ns (typ) at +5V - supports fast multiplexing in automated test equipment and real-time control loops. |
Pinout & Package
MAX4620EUD+ is housed in a 14-pin Thin Shrink Small Outline Package (TSSOP) with 0.65mm pitch, 5.0mm × 4.4mm body, and exposed pad option (not thermally enhanced in this variant). Pin 7 is GND; Pin 14 is V+; Pins 1,3,8,11 are NO1–NO4; Pins 2,4,9,10 are COM1–COM4; Pins 5,6,12,13 are IN2–IN4 and IN1 respectively.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,3,8,11 (NO1–NO4) | Normally Open Switch Terminal | Connects to COMx only when corresponding INx is HIGH; rated for ±15kV ESD and ±10mA continuous current. |
| 2,4,9,10 (COM1–COM4) | Common Analog Node | Carries bidirectional rail-to-rail signals; off-leakage ≤5nA over temperature ensures accuracy in precision measurement paths. |
| 5,6,12,13 (IN2–IN4, IN1) | TTL/CMOS Digital Control Input | Accepts 0.8V/2.4V logic thresholds; input leakage ≤±1µA avoids loading of driving microcontrollers or FPGAs. |
| 7 (GND) | Analog/Digital Ground Reference | Shared return for supply and signal paths; must be low-impedance to maintain ESD SCR clamping effectiveness. |
| 14 (V+) | Positive Supply Input | Supplies internal switch bias and logic; bypassing with 0.1µF ceramic capacitor near pin is mandatory for >8V operation. |
Key Features
| Feature | Design Value |
|---|---|
| Quad NO configuration | Four independent normally open switches simplify discrete relay replacement in 4-channel signal routing without NC complexity. |
| Guaranteed on-resistance flatness | 2Ω (typ) at +5V - minimizes harmonic distortion and gain error across full analog input range (0V to V+). |
| Bidirectional SCR ESD protection | ±15kV air-gap discharge tolerance - provides self-resetting clamping without latch-up, eliminating external protection components. |
| Rail-to-rail signal handling | Supports analog inputs from 0V to V+ - enables direct interfacing with op-amps, ADCs, and DACs without level-shifting circuitry. |
| Low power consumption | 1µA typical supply current - extends battery life in portable medical monitors and handheld test instruments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4610ESA+ | Single SPST NO switch in 8-pin SO; 60Ω max RON at +5V; same ESD rating but lower integration density. | Requires four devices to match MAX4620EUD+ channel count; higher board area and interconnect complexity. | Select when space permits discrete layout or when individual channel enable timing is required. |
| ADG1419BRUZ | Quad SPST NO switch in 16-pin TSSOP; 8Ω max RON at +5V; ±20kV ESD; requires dual ±15V or +12V/−5V supplies. | Superior on-resistance and bandwidth but incompatible with single +3.3V/+5V battery systems due to supply constraints. | Select for ultra-low-RON industrial PLC I/O modules where dual-supply infrastructure exists. |
Compared with MAX4610ESA+, MAX4620EUD+ reduces component count and PCB footprint by 75% for quad-channel routing; compared with ADG1419BRUZ, it enables true single-supply portability at the cost of higher on-resistance-making it optimal for compact, battery-operated instrumentation where supply simplicity outweighs milliohm-level losses.

FAQ
What is the maximum supply voltage rating for MAX4620EUD+?
The MAX4620EUD+ has an absolute maximum V+ rating of +13V referenced to GND, with functional operation guaranteed from +2V to +12V. Operation above +12V requires strict adherence to bypassing (0.1µF ceramic capacitor placed directly at Pin 14 to GND) and thermal derating per the datasheet's power dissipation curves. Exceeding +13V risks permanent damage.
Does MAX4620EUD+ support rail-to-rail analog signals?
Yes, MAX4620EUD+ supports rail-to-rail analog signals from 0V to V+, meaning it can pass input voltages equal to the positive supply rail or ground without clipping or distortion. This capability is enabled by its CMOS process and internal level-shifting design, making it suitable for interfacing directly with op-amps, ADCs, and DACs operating at the same supply voltage.
How does the ESD protection in MAX4620EUD+ work without latch-up?
MAX4620EUD+ uses on-chip bidirectional silicon-controlled rectifiers (SCRs) between NO/NC pins and GND to clamp ±15kV ESD transients. Once triggered, the SCR remains latched until current falls below its holding threshold (~110mA at +25°C). The device avoids latch-up because the SCR is designed to self-reset when external current sources are limited below 70mA (worst-case at +85°C), ensuring reliable recovery after ESD events.
Can MAX4620EUD+ replace the 74HC4066 in existing designs?
Yes, MAX4620EUD+ is explicitly specified as a pin-compatible replacement for the 74HC4066, sharing identical 14-pin TSSOP pinout, logic-level compatibility (TTL/CMOS inputs), and SPST NO functionality. However, MAX4620EUD+ adds ±15kV ESD protection, lower on-resistance (70Ω vs. ~100Ω), and guaranteed flatness-requiring no PCB changes but offering improved robustness and signal fidelity.
What is the typical on-resistance matching between channels in MAX4620EUD+?
The typical on-resistance matching (∆RON = RON(MAX) − RON(MIN)) for MAX4620EUD+ is 0.5Ω at +5V and +25°C, with a maximum of 3Ω over the full operating temperature range (−40°C to +85°C). This tight matching ensures consistent gain and phase response across all four channels in multi-path signal processing applications like balanced audio or differential sensor multiplexing.
