Product details
Overview
MAX4568EUK+T from Maxim Integrated is a ±15kV ESD-protected, single-pole/single-throw (SPST) normally open (NO) analog switch in 5-pin SOT23 package, operating from +1.8V to +12V supply, with 70Ω on-resistance at +5V, 4Ω max on-resistance flatness, and 0.5nA off-leakage at +25°C - used for robust signal routing in battery-powered audio/video systems.
For engineers reviewing the MAX4568EUK+T datasheet, MAX4568EUK+T pinout, MAX4568EUK+T application, or MAX4568EUK+T equivalent, key selection criteria include ESD robustness (±15kV HBM/IEC air-gap), rail-to-rail analog handling, low leakage across temperature, guaranteed on-resistance match, and compatibility with TTL/CMOS logic at +5V.
Technical Context
The MAX4568EUK+T implements a CMOS transmission-gate architecture with integrated bidirectional SCRs on NO and NC terminals for ±15kV IEC 1000-4-2 air-gap and human-body ESD protection. Its control logic accepts +0.8V to +2.4V thresholds, enabling direct interface with +5V TTL/CMOS without level shifting.
It supports rail-to-rail analog signal switching up to V+ = +12V, with on-resistance flatness of ≤4Ω over full signal range and guaranteed break-before-make timing not applicable (SPST-NO configuration). The device draws only 1µA typical supply current at +25°C and features 20pF NO/NC off-capacitance and 12pF COM off-capacitance at +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +12V - enables operation from single-cell Li-ion to industrial rails without external regulation |
| On-Resistance (RON) | 70Ω max at +5V - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-Resistance Flatness | 4Ω max - maintains consistent gain and linearity across full 0V to V+ analog input range |
| Off-Leakage Current | 5nA max at +85°C - preserves accuracy in high-impedance sample-and-hold or sensor front-ends |
| ESD Protection | ±15kV HBM & IEC 1000-4-2 air-gap on NO/NC - eliminates need for external TVS diodes in handheld interfaces |
| Logic Compatibility | +0.8V to +2.4V input thresholds - ensures reliable switching with standard +5V CMOS/TTL drivers |
| Turn-On/Off Time | 180ns/100ns max - supports audio-band and low-speed data-acquisition switching without timing constraints |
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, 2.9mm × 1.6mm footprint, and thermal pad omitted - suitable for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO | Normally open analog terminal - connects to COM only when IN = logic high; rated for ±15kV ESD |
| 2 | V+ | Positive supply input - must be bypassed with ≥0.1µF capacitor to GND near pin for ESD immunity and stability |
| 3 | GND | Ground reference - shared return for analog and digital domains; critical for SCR-based ESD path integrity |
| 4 | IN | Digital control input - TTL/CMOS-compatible; rising edge enables NO-to-COM conduction |
| 5 | COM | Common analog terminal - carries rail-to-rail signals up to V+; protected to ±2.5kV ESD |
Key Features
| Feature | Design Value |
|---|---|
| ±15kV ESD protection on NO/NC | Eliminates external protection components in USB ports, headphone jacks, and industrial I/O connectors |
| Rail-to-rail analog signal handling | Supports full-scale sensor outputs (e.g., 0–5V thermocouple amps) without clipping or distortion |
| 70Ω on-resistance at +5V | Minimizes insertion loss in audio routing paths (<0.3dB at 600Ω load) and preserves ADC dynamic range |
| 4Ω on-resistance flatness | Ensures <0.1% THD in 20Hz–20kHz audio applications and stable gain in programmable-gain amplifiers |
| 0.5nA off-leakage at +25°C | Enables >10MΩ effective isolation in high-impedance medical electrode multiplexing |

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 | Same 5-pin SOT23 package and pinout; identical ±15kV ESD rating but 100Ω RON at +5V (vs. 70Ω) | Suitable where higher on-resistance is acceptable for cost-sensitive consumer audio | Select MAX4514EUK+T if budget constraints outweigh 30Ω RON penalty and leakage specs align |
| TMUX1101DBVR | Lower 0.5Ω RON but only ±2kV HBM ESD rating; requires external protection in harsh environments | Preferred in lab-grade data loggers with controlled ESD zones and ultra-low-loss requirements | Choose TMUX1101DBVR only when board-level ESD mitigation is already implemented and sub-1Ω RON is mandatory |
Compared with MAX4514EUK+T, MAX4568EUK+T delivers 30Ω lower on-resistance for improved signal fidelity; versus TMUX1101DBVR, it trades 0.5Ω RON for integrated ±15kV ESD robustness - making it optimal for unshielded portable or industrial interfaces where reliability trumps marginal RON reduction.

FAQ
What is the maximum supply voltage rating for MAX4568EUK+T?
The MAX4568EUK+T has an absolute maximum supply voltage (V+) of +13V referenced to GND. It operates reliably across +1.8V to +12V, with on-resistance degrading above +12V. For +12V operation, a minimum 0.1µF ceramic bypass capacitor must be placed directly between V+ and GND pins to maintain ESD immunity and prevent supply rail coupling during SCR latch events.
Does MAX4568EUK+T support rail-to-rail analog signal switching?
Yes, MAX4568EUK+T supports true rail-to-rail analog signal handling - its analog terminals (NO, COM) pass signals from 0V up to V+ without clipping or distortion. This is enabled by its CMOS transmission-gate design and internal level-shifting circuitry, allowing direct interfacing with sensors, DACs, and ADCs operating at full supply rails.
What is the ESD protection level on the COM pin of MAX4568EUK+T?
The COM pin of MAX4568EUK+T is protected to ±2.5kV per IEC 1000-4-2 and ±2.5kV per Human Body Model, as confirmed in the Absolute Maximum Ratings table. This is lower than the ±15kV rating on NO/NC pins because COM lacks integrated SCRs and relies on diode clamping to V+ and GND - sufficient for most system-level ESD but not direct user-contact points.
Can MAX4568EUK+T be used with a +3V supply?
Yes, MAX4568EUK+T is fully specified for +3V operation: on-resistance is 120Ω max, turn-on time is 300ns max, and logic thresholds shift to VIH = +2.0V / VIL = +0.6V. Its 1.8V minimum supply enables use with single Li-ion cells (2.7–4.2V) and regulated 3.3V rails, maintaining 5nA off-leakage at +85°C for long battery life.
Is MAX4568EUK+T pin-compatible with other Maxim analog switches?
Yes, MAX4568EUK+T uses the industry-standard 5-pin SOT23 pinout and is explicitly pin-compatible with MAX4514EUK+T and MAX4515EUK+T per the datasheet's "Features" section - enabling drop-in replacement in existing layouts where ESD robustness or on-resistance matching is upgraded without PCB revision.
