Product details
Overview
The MAX4568EUK-T from Maxim Integrated is a single-pole/single-throw (SPST), normally open (NO) analog switch optimized for low-voltage, high-ESD-sensitivity signal routing. It operates from +1.8V to +12V, delivers 70Ω on-resistance at +5V, supports rail-to-rail analog signals, and provides ±15kV HBM ESD protection on NO/NC terminals-enabling robust audio switching in portable medical sensors.
For engineers reviewing the MAX4568EUK-T datasheet, MAX4568EUK-T pinout, MAX4568EUK-T application, or MAX4568EUK-T equivalent, key selection criteria include its 5-pin SOT23 package, guaranteed 2Ω max on-resistance match, 0.5nA off-leakage at +25°C, and TTL/CMOS logic compatibility with +5V supply-critical for battery-powered data-acquisition front-ends.
Technical Context
This SPST NO switch uses CMOS process technology with integrated bidirectional SCRs on NO/NC terminals to achieve ±15kV IEC 1000-4-2 air-gap and HBM ESD protection. Its analog path handles rail-to-rail signals up to V+ while maintaining flat on-resistance (≤4Ω variation over full signal range) and low charge injection (6pC typical).
Digital control accepts +0.8V to +2.4V logic thresholds for reliable operation with +5V TTL/CMOS systems. The device features guaranteed break-before-make timing only in the MAX4561 SPDT variant-not applicable to MAX4568EUK-T-and exhibits 150ns max turn-on time at +5V with 35pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | SPST, Normally Open (NO)-enables simple signal path enable/disable without NC terminal routing |
| Supply Voltage Range | +1.8V to +12V-supports direct integration into Li-ion (3.3V/3.7V) and industrial (5V/9V/12V) power domains |
| On-Resistance (RON) | 70Ω at +5V-ensures minimal signal attenuation and voltage drop in precision sensor interfaces |
| On-Resistance Match | ≤2Ω max between channels-critical for matched gain paths in differential or dual-channel instrumentation |
| Off-Leakage Current | 0.5nA at +25°C-preserves accuracy in high-impedance sample-and-hold or pH probe circuits |
| ESD Protection | ±15kV HBM / ±15kV IEC 1000-4-2 air-gap on NO-eliminates need for external TVS diodes in handheld test equipment |
| Logic Compatibility | +0.8V to +2.4V input thresholds-guarantees clean switching with standard +5V microcontroller GPIOs |
Pinout & Package
MAX4568EUK-T is housed in a RoHS-compliant 5-pin SOT23 package (package code U5+2, outline 21-0057), with 0.95mm pitch and 2.9mm × 1.6mm footprint-compatible with standard automated pick-and-place and reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Logic control input-active-high enables NO-to-COM conduction; ties directly to MCU output |
| 2 | V+ | Positive supply rail-must be bypassed with ≥0.1µF capacitor to GND near pin for ESD immunity |
| 3 | GND | Analog/digital ground reference-shared return for supply, logic, and signal paths |
| 4 | NC | No connection-pin 4 is unconnected in MAX4568EUK-T (distinct from MAX4569's NC configuration) |
| 5 | COM | Common analog terminal-routes signal to NO when IN = high; connects to sensor output or DAC |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs from GND to V+-enables full-scale use of ADC dynamic range in 3.3V systems |
| Guaranteed on-resistance flatness | ≤4Ω variation across signal range-minimizes harmonic distortion in audio band (20Hz–20kHz) |
| Low charge injection | 6pC typical-reduces settling error in sample-and-hold stages after switching |
| Industry-standard pinout | PIN-compatible with MAX4514-allows drop-in replacement in existing layouts using same footprint |
| ESD-protected NO terminal | ±15kV IEC 1000-4-2 contact discharge-meets Level 4 immunity for medical handheld devices per IEC 60601-1-2 |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4514EUK+T | Identical 5-pin SOT23 pinout, same ±15kV ESD rating, but 100Ω RON at +5V (vs. 70Ω) | Suitable where lower cost outweighs 30Ω higher on-resistance; acceptable in non-precision audio routing | Select MAX4514EUK+T if budget constraints dominate and RON tolerance >100Ω is acceptable. |
| ADG849BRMZ-REEL7 | 3.3V-only supply (1.8–3.6V), 0.5Ω RON match, but only ±4kV HBM ESD rating | Requires external ESD protection in handheld environments; better for board-level protected industrial modules | Choose ADG849BRMZ-REEL7 only in fully enclosed, low-ESD-risk systems with added board-level TVS. |
Compared with MAX4568EUK-T, MAX4514EUK+T trades 30Ω higher on-resistance for lower unit cost, while ADG849BRMZ-REEL7 offers superior matching and lower RON but lacks system-level ESD robustness-making MAX4568EUK-T optimal for unshielded, user-accessible signal paths.

FAQ
What is the maximum supply voltage supported by the MAX4568EUK-T?
The MAX4568EUK-T supports a maximum supply voltage of +12V, with absolute maximum rating of +13V referenced to GND. Operation at +12V requires a minimum 0.1µF bypass capacitor from V+ to GND placed adjacent to the device to maintain ESD immunity and stability, as specified in the Applications Information section of the MAX4568EUK-T datasheet.
Does the MAX4568EUK-T provide break-before-make functionality?
No, the MAX4568EUK-T does not provide break-before-make functionality. That feature is guaranteed only for the MAX4561EUT+T SPDT variant (with 5ns typical delay). The MAX4568EUK-T is an SPST NO switch with no NC terminal or associated timing specification-its switching action is simple make/break without overlap or intentional dead-time control.
What is the on-resistance flatness specification for the MAX4568EUK-T at +5V?
The MAX4568EUK-T guarantees on-resistance flatness of ≤4Ω maximum over the full analog signal range (0V to V+) when operated at +5V supply. This parameter-defined as the difference between maximum and minimum RON measured at VCOM = 1V, 2.25V, and 3.5V-is critical for minimizing harmonic distortion in audio and precision measurement applications.
Can the MAX4568EUK-T operate from a +3.3V supply, and what is its on-resistance in that condition?
Yes, the MAX4568EUK-T operates from +3.3V (within its +2.7V to +3.6V specified range for +3V mode). At +3.3V, typical on-resistance is 120Ω, with a maximum of 150Ω across temperature. This value is confirmed in the Electrical Characteristics table for Single +3V Supply, ensuring predictable performance in modern low-voltage embedded systems.
Is the MAX4568EUK-T pin-compatible with any other Maxim analog switches?
Yes, the MAX4568EUK-T is pin-compatible with the MAX4514EUK+T in the 5-pin SOT23 package, sharing identical pin assignments (IN, V+, GND, NC, COM). This allows direct substitution in existing layouts. However, note that MAX4514EUK+T has higher on-resistance (100Ω vs. 70Ω at +5V) and slightly different ESD test margin documentation-verify system-level immunity requirements before replacement.
