Product details
Overview
The MAX4620EUD from Maxim Integrated is a low-voltage, ±15kV ESD-protected, quad single-pole/single-throw (SPST) analog switch with four normally open (NO) channels, 70Ω max on-resistance at +5V, 0.5nA off-leakage at +25°C, and rail-to-rail signal handling - used in battery-powered audio routing and automated 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, 14-pin TSSOP package, and ESD robustness per IEC 1000-4-2 air-gap (±15kV) and contact (±8kV) discharge standards.
Technical Context
The MAX4620EUD implements four independent CMOS SPST switches, each controlled by a dedicated TTL/CMOS-level digital input (IN1–IN4), with NO/NC pins protected by on-chip bidirectional SCRs that latch at ~3V and require current limiting below 70mA at +85°C to ensure turn-off after ESD events.
It operates from a single +2V to +12V supply, supports rail-to-rail analog signals (0V to V+), delivers >300MHz -3dB bandwidth, and achieves 0.015% THD in 20Hz–20kHz audio paths - all while consuming only 1µA typical supply current and exhibiting matched on-resistance (0.5Ω typ) and flat on-resistance (2Ω typ) over its full signal range.

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 for thermal enhancement (not electrically connected). 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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (COM1) | Analog Switch 1 – Common terminal | Signal path junction between NO1 and system load; rail-to-rail capable; 12pF off-capacitance |
| 5 (IN2) | Digital Control Input 2 | TTL/CMOS-compatible (VIH = 2.4V min, VIL = 0.8V max); controls NO2/COM2 state |
| 7 (GND) | Ground reference | Return path for supply and logic; must be low-impedance for ESD current dissipation |
| 14 (V+) | Positive Supply Voltage Input | Accepts +2V to +12V; requires 0.1µF bypass capacitor near pin for high-voltage stability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4610EUD | Single-supply +2.7V to +12V; 75Ω max RON at +5V; same 14-TSSOP package; no ESD rating specified in datasheet | Lacks ±15kV ESD protection on NO/NC pins - requires external protection in connector-facing designs | Select when ESD robustness is not required and legacy compatibility with MAX4610 footprint is critical |
| ADG1419BRUZ | +5V/+15V dual-supply operation; 1.3Ω max RON; 16-pin TSSOP; ±20kV HBM ESD; higher supply current (200µA) | Requires dual supply and larger PCB footprint; superior RON but incompatible pinout and control logic | Select for ultra-low on-resistance in precision instrumentation where dual supply is available and layout redesign is acceptable |
Compared with MAX4610EUD, MAX4620EUD adds certified ±15kV ESD protection and tighter on-resistance matching (0.5Ω vs. unspecified), while ADG1419BRUZ offers lower RON but demands dual supplies and cannot replace MAX4620EUD without schematic and layout changes.

FAQ
What is the maximum supply voltage rating for the MAX4620EUD?
The MAX4620EUD has an absolute maximum V+ rating of +13V referenced to GND, but its specified operational range is +2V to +12V. Operation near +12V requires a minimum 0.1µF ceramic bypass capacitor placed directly between Pin 14 (V+) and Pin 7 (GND) to suppress supply transients induced by ESD SCR conduction. Exceeding +13V risks permanent damage.
Does the MAX4620EUD support rail-to-rail analog signal switching?
Yes, the MAX4620EUD supports true rail-to-rail analog signal switching - its COM, NO, and NC terminals handle voltages from 0V to V+ without distortion or clipping. This capability is enabled by its CMOS process and internal level-shifting circuitry, making it suitable for interfacing directly with ADCs, DACs, and op-amps operating at the supply rails.
How does the ESD protection mechanism work in the MAX4620EUD?
The MAX4620EUD uses on-chip bidirectional silicon-controlled rectifiers (SCRs) between NO/NC pins and GND to clamp ±15kV ESD strikes. When triggered, the SCR latches until current falls below its holding current (~110mA at +25°C, ~70mA at +85°C). System design must current-limit external sources connected to NO/NC to <35mA to guarantee safe turn-off after discharge.
What is the on-resistance flatness specification for the MAX4620EUD at +5V?
At +5V supply and +25°C, the MAX4620EUD exhibits 2Ω typical on-resistance flatness - 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 audio and video signal paths, especially critical in AC-coupled applications.
Can the MAX4620EUD replace the 74HC4066 in existing designs?
Yes, the MAX4620EUD is explicitly designed as a pin-compatible replacement for the 74HC4066, sharing identical 14-pin TSSOP/SO/DIP footprints and logic-level control (TTL/CMOS compatible). It improves upon the 74HC4066 with ±15kV ESD protection, lower on-resistance (70Ω vs. ~100Ω), and guaranteed leakage (0.5nA vs. ~100nA), requiring no PCB changes but offering enhanced reliability.
