Product details
Overview
The MAX4620EUD-T from Maxim Integrated is a low-voltage, ±15kV ESD-protected, quad 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-designed for audio routing and battery-powered test equipment where mechanical relay replacement is required.
For engineers reviewing the MAX4620EUD-T datasheet, MAX4620EUD-T pinout, MAX4620EUD-T application, or MAX4620EUD-T equivalent, key selection criteria include guaranteed on-resistance flatness (2Ω typ), TTL/CMOS-compatible control inputs, single +2V to +12V supply operation, and ESD robustness per IEC 1000-4-2 air-gap (±15kV) and contact (±8kV) discharge standards.
Technical Context
This device implements CMOS-based SPST switching with integrated bidirectional SCRs on NO/NC terminals for ±15kV HBM and IEC 1000-4-2 ESD protection. Each channel operates bilaterally with rail-to-rail analog signal range and features guaranteed turn-on/off times (150ns/80ns typ at +5V) and <0.015% THD across 20Hz–20kHz.
The MAX4620EUD-T uses a 14-pin TSSOP package with dedicated INx control inputs and isolated NOx/COMx paths. Its on-resistance matching (0.5Ω typ at +5V) and flatness (2Ω typ) ensure minimal crosstalk (<−90dB at 1MHz) and consistent signal integrity across all four switches under varying VCOM conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 70Ω at +5V - ensures low insertion loss and minimal voltage drop in signal paths up to ±5V |
| Off-Leakage Current | 0.5nA at +25°C - preserves accuracy 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 field-deployable systems |
| Supply Range | +2V to +12V single supply - supports direct integration into 3.3V, 5V, and 9V battery-powered designs without level-shifting |
| Bandwidth (-3dB) | >300MHz - enables clean switching of video, RF sampling, and high-speed data signals |
| THD + Noise | 0.015% at 600Ω load - meets fidelity requirements for professional audio routing and instrumentation-grade signal chains |
| Turn-On/Off Time | 150ns/80ns typ at +5V - supports multiplexing rates up to ~5MHz in data acquisition systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4610EUD-T | Single SPST NO switch; same 70Ω RON, 0.5nA leakage, and ±15kV ESD rating but only one channel | Suitable for point-of-use switching where quad density is unnecessary and board space is constrained | Select MAX4610EUD-T when only one switch is needed and layout area must be minimized |
| ADG1414BRUZ | Quad SPST NO switch with 1.8Ω RON (typ), −40°C to +125°C temp range, but only ±4kV HBM ESD rating | Better for high-precision, high-temp industrial control; lacks ESD robustness for handheld or field-test use | Choose ADG1414BRUZ for ultra-low on-resistance needs in benign ESD environments |
Compared with MAX4610EUD-T and ADG1414BRUZ, the MAX4620EUD-T uniquely delivers quad-channel density, ±15kV ESD protection, and rail-to-rail operation within a single 14-pin TSSOP-making it optimal for space-constrained, field-deployable systems requiring reliability and signal integrity.

FAQ
What is the maximum supply voltage rating for the MAX4620EUD-T?
The MAX4620EUD-T has an absolute maximum supply voltage (V+) of +13V referenced to GND, with guaranteed functional operation from +2V to +12V. Operation near +12V requires a minimum 0.1µF ceramic bypass capacitor placed close to the V+ and GND pins to suppress supply transients induced during ESD events or fast switching.
Does the MAX4620EUD-T require external ESD protection components?
No, the MAX4620EUD-T does not require external ESD protection components on its NO/NC pins. It integrates on-die bidirectional SCRs that provide ±15kV protection per IEC 1000-4-2 air-gap discharge and ±8kV per contact discharge, meeting Level 4 system-level ESD immunity without added discretes.
Can the MAX4620EUD-T switch signals beyond the supply rails?
No, the MAX4620EUD-T cannot switch signals beyond the supply rails. Its analog input voltage range is strictly 0V to V+, and signals exceeding these limits are clamped by internal diodes. For Beyond-the-Rails™ operation, consider Maxim's MAX469x family, which explicitly supports overvoltage tolerant switching.
What is the typical on-resistance flatness of the MAX4620EUD-T at +3V supply?
At +3V supply, the MAX4620EUD-T exhibits 6Ω typical on-resistance flatness over the full analog signal range (0V to +3V). This value is specified in the +3V electrical characteristics table and reflects the peak-to-peak variation in RON as VCOM sweeps across the rail-to-rail span.
Is the MAX4620EUD-T pin-compatible with the 74HC4066?
Yes, the MAX4620EUD-T is pin-compatible with the industry-standard 74HC4066 quad analog switch. Both devices use the same 14-pin SO/TSSOP/DIP footprint and share identical pin assignments for INx, COMx, NOx, V+, and GND-enabling drop-in replacement without PCB redesign.
