Product details
Overview
MAX4620EUD+T from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO) analog switch IC designed for low-voltage signal routing in precision analog systems. 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 up to 300MHz bandwidth-ideal for battery-powered audio routing and data-acquisition front-ends.
For engineers reviewing the MAX4620EUD+T datasheet, MAX4620EUD+T pinout, MAX4620EUD+T application, or MAX4620EUD+T equivalent, key selection criteria include ±15kV HBM ESD protection on NO/NC pins, guaranteed on-resistance matching (0.5Ω typ), TTL/CMOS-compatible control inputs, low distortion (0.015%), and TSSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4620EUD+T implements four independent CMOS SPST switches with bidirectional SCR-based ESD protection on all NO terminals, enabling ±15kV air-gap and contact discharge immunity without latchup. Its architecture ensures rail-to-rail signal handling and bilateral operation, with logic-level inputs directly compatible with TTL and CMOS voltage thresholds (VIH = 2.4V, VIL = 0.8V at 5V).
Each switch features guaranteed on-resistance flatness (2Ω typ at 5V), matched channel resistance (0.5Ω typ), and sub-nanoampere leakage-critical for high-impedance sample-and-hold and sensor multiplexing. The device is specified across –40°C to +85°C and draws only 1µA typical supply current at +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 9V battery systems without level-shifting. |
| On-Resistance (max) | 70Ω at 5V - ensures minimal signal attenuation and gain error in precision instrumentation paths. |
| Off-Leakage Current | ±0.5nA at TA = +25°C - preserves accuracy in high-impedance (>1MΩ) sensor and DAC output switching. |
| -3dB Bandwidth | >300MHz - supports video, RF sampling, and fast data-acquisition signal routing without roll-off. |
| ESD Protection | ±15kV HBM, ±15kV IEC 1000-4-2 air-gap, ±8kV contact - eliminates need for external TVS diodes in handheld or field-deployable equipment. |
| THD + Noise | 0.015% at 20Hz–20kHz - meets fidelity requirements for professional audio signal path switching. |
| Turn-On/Off Time | 90ns/50ns typ at 5V - enables precise timing control in multiplexed ADC/DAC interfaces and automated test sequencing. |
Pinout & Package
MAX4620EUD+T is housed in a 14-pin Thin Shrink Small Outline Package (TSSOP) with 0.65mm pitch, optimized for compact PCB layouts and thermal performance in industrial and portable applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog switch terminals - connect to signal sources only when corresponding INx is HIGH; isolated otherwise. |
| 2, 4, 9, 10 | COM1–COM4 | Common analog node per switch - serves as bidirectional signal path between NO and load/sink. |
| 5–6, 12–13 | IN2–IN4, IN1 | TTL/CMOS digital control inputs - drive respective NO/COM path ON (HIGH) or OFF (LOW) with no external pull-ups required. |
| 7 | GND | Analog/digital ground reference - must be low-impedance connection to minimize noise coupling into analog channels. |
| 14 | V+ | Positive supply input - bypass with 0.1µF ceramic capacitor close to pin to suppress ESD transients and supply ripple. |
Key Features
| Feature | Design Value |
|---|---|
| ±15kV ESD protection on NO pins | Integrated SCRs eliminate need for external protection components and prevent latchup during handling or field operation. |
| On-resistance matching | 0.5Ω typical between channels at 5V - ensures consistent gain and phase response across multiplexed signal paths. |
| Rail-to-rail analog signal range | Supports full V+ to GND swing - enables seamless interfacing with op-amps, ADCs, and DACs operating at supply rails. |
| Low distortion | 0.015% THD+N - preserves signal integrity in audio line-level switching and precision measurement front-ends. |
| Guaranteed 0.5nA leakage | Validated at +25°C and correlated over temperature - critical for maintaining accuracy in high-Z sample-and-hold and sensor multiplexing. |

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; 80Ω max RON at 5V; same ESD rating and leakage specs. | Lower channel count requires four devices to match MAX4620EUD+T's quad functionality; larger board footprint. | Select when board layout permits discrete channel isolation or when thermal derating favors smaller packages. |
| ADG1412BRUZ | Quad SPST NO switch in 16-pin TSSOP; 1.8Ω max RON at 5V; ±15kV HBM but no IEC 1000-4-2 certification. | Superior on-resistance and lower charge injection (0.2pC), but lacks guaranteed IEC-level ESD robustness for industrial field use. | Select for ultra-low-distortion lab-grade instrumentation where ESD exposure is controlled and RON matching is paramount. |
Compared with MAX4610ESA+, MAX4620EUD+T integrates four channels in one TSSOP-14 package, reducing component count and interconnect parasitics. Against ADG1412BRUZ, it trades lower RON for broader ESD compliance-making it preferred for ruggedized portable and industrial deployments where field reliability outweighs marginal on-resistance gains.

FAQ
What is the maximum supply voltage rating for MAX4620EUD+T?
The MAX4620EUD+T 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 IC pad to suppress ESD-induced supply transients and ensure stable switching behavior.
Does MAX4620EUD+T support rail-to-rail analog signal switching?
Yes, MAX4620EUD+T fully supports rail-to-rail analog signal switching-the input voltage range on COM, NO, and NC pins extends from GND to V+ across the full operating temperature range. This enables direct interfacing with op-amps, ADCs, and DACs operating at supply rails without signal clipping or distortion.
What is the on-resistance matching specification for MAX4620EUD+T?
The MAX4620EUD+T guarantees on-resistance matching (∆RON) of 0.5Ω typical and 3Ω maximum at +25°C with V+ = 4.5V. This tight matching ensures uniform gain and phase response across all four channels-essential for multi-channel instrumentation, balanced audio routing, and precision multiplexing applications.
Can MAX4620EUD+T replace the 74HC4066 in existing designs?
Yes, MAX4620EUD+T is explicitly designed as a pin-compatible replacement for the 74HC4066, offering identical 14-pin TSSOP/SO/DIP footprints and logic-level compatibility. It improves upon the 74HC4066 with ±15kV ESD protection, lower on-resistance (70Ω vs. ~100Ω), and guaranteed leakage performance-requiring no PCB changes for drop-in upgrades.
What ESD standards does MAX4620EUD+T meet on its NO pins?
MAX4620EUD+T meets ±15kV per Human Body Model (HBM), ±15kV per IEC 1000-4-2 air-gap discharge, and ±8kV per IEC 1000-4-2 contact discharge on all NO pins. These ratings are achieved via integrated bidirectional SCRs and series current-limiting resistors-enabling system-level IEC 61000-4-2 Level 4 compliance without external protection components.
