Product details
Overview
MAX4853ETE from Maxim Integrated is a quad SPST analog switch IC designed for USB 2.0 full-speed (12Mbps) and audio signal routing in portable electronics. It operates from a single +2V to +5.5V supply, delivers 3.5Ω on-resistance on channels 1 and 3, 7Ω on channels 2 and 4, supports over-rail signal handling up to 5.5V, and features 150MHz -3dB bandwidth with 0.01µA supply current at VCC = 5.5V.
For engineers reviewing the MAX4853ETE datasheet, MAX4853ETE pinout, MAX4853ETE application, or MAX4853ETE equivalent, this page provides verified electrical parameters, package-validated pin functions, confirmed over-rail pass-through behavior, and real-world USB/audio switching use cases - all specific to the MAX4853ETE variant without comparator circuitry.
Technical Context
The MAX4853ETE implements four independent SPST switches with asymmetric on-resistance: NO1/COM1 and NO3/COM3 use 3.5Ω switches optimized for low-loss D+/D− USB data paths, while NO2/COM2 and NO4/COM4 use 7Ω switches suited for lower-bandwidth audio or control signals. All switches support bidirectional signal flow and tolerate analog inputs up to 5.5V regardless of VCC (2.0V–5.5V), enabling robust interface bridging between mixed-voltage subsystems.
Unlike the MAX4851 series, the MAX4853ETE omits the integrated comparator and CIN/COUT pins, simplifying layout for pure switching applications. Its 16-pin 3mm × 3mm thin QFN package with exposed paddle ensures thermal stability in space-constrained handheld designs, and its guaranteed 1ns skew across channels meets USB 2.0 full-speed timing integrity requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +5.5V - enables direct interfacing with 2.5V, 3.3V, and 5V logic domains without level shifters |
| On-Resistance (Ch1/Ch3) | 3.5Ω max at VCC = 3V, TA = +85°C - minimizes insertion loss and voltage drop in high-fidelity USB D+/D− paths |
| On-Resistance (Ch2/Ch4) | 7Ω max at VCC = 3V, TA = +85°C - balances low capacitance and power efficiency for auxiliary audio/control lines |
| -3dB Bandwidth | 150MHz - supports clean transmission of USB 2.0 full-speed (12Mbps) eye diagrams with <1ns skew |
| Supply Current | 0.01µA typical at VCC = 5.5V - enables always-on USB detection or audio mute switching in battery-powered devices |
| Over-Rail Handling | Pass-through mode up to 5.5V - allows unclamped analog signals exceeding VCC (e.g., 5V USB signals on 3.3V systems) |
| Operating Temperature | -40°C to +85°C - qualified for industrial and mobile end equipment environments |
Pinout & Package
MAX4853ETE is housed in a 16-pin, 3mm × 3mm thin QFN package with exposed thermal pad (EP), compatible with standard reflow profiles and offering low-inductance grounding via the soldered EP connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 7, 10, 12 | NO1, NO2, NO3, NO4, COM4 | Normally open and common terminals for four independent SPST analog switches; bidirectional, rail-to-rail capable |
| 3, 9, 13, 15 | IN1, IN2, IN3, IN4 | Digital control inputs accepting 1.4V/1.8V logic thresholds - compatible with 1.8V, 2.5V, 3.3V, and 5V GPIO |
| 4, 8, 16 | COM2, COM3, COM1 | Common analog I/O nodes; each pairs with corresponding NOx pin to form a complete switch path |
| 6 | GND | Ground reference for analog and digital sections; must be connected to system ground plane |
| 14 | VCC | Single positive supply input; requires local 0.01µF ceramic bypass capacitor to GND |
| 2, 11 | N.C. | No internal connection - left floating per MAX4853-specific pinout (no comparator circuitry) |
| EP | GND (exposed pad) | Thermal and electrical ground tie; must be soldered to PCB ground plane for thermal dissipation and noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetric on-resistance configuration | 3.5Ω on Ch1/Ch3 + 7Ω on Ch2/Ch4 - optimizes USB signal integrity while reducing leakage and capacitance on auxiliary lines |
| Over-rail pass-through capability | Signals up to 5.5V pass undistorted even at VCC = 2.0V - eliminates need for external clamping diodes in mixed-voltage USB interfaces |
| Ultra-low quiescent current | 0.01µA typical ICC at VCC = 5.5V - extends battery life in always-on USB accessory detection or headset presence circuits |
| Guaranteed 1ns channel-to-channel skew | Measured at RS = 39Ω, CL = 50pF - ensures matched D+/D− propagation for USB 2.0 full-speed compliance |
| 150MHz -3dB bandwidth | Validated with RL = 50Ω, CL = 5pF - preserves rise/fall times and eye opening for 12Mbps data streams |

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 |
|---|---|---|---|
| MAX4851ETE | Includes integrated comparator (CIN/COUT pins); 3.5Ω on all four channels; 5µA supply current | Suitable for headphone detection/mute key sensing; not drop-in due to extra pins and higher ICC | Select MAX4851ETE only if comparator functionality is required; MAX4853ETE saves board space and power when comparator is unused |
| TS5A3157DCKR | Single 2:1 SPDT switch (not quad SPST); 0.75Ω on-resistance; 1.65V–5.5V supply; no over-rail capability | Limited to single-path switching; cannot replace quad topology without redesign | Use TS5A3157DCKR only for point-to-point signal routing where over-rail handling and multi-channel integration are unnecessary |
Compared with MAX4851ETE and TS5A3157DCKR, the MAX4853ETE uniquely combines quad SPST topology, asymmetric resistance optimization, over-rail pass-through, and sub-µA quiescent current - making it the only option that satisfies USB 2.0 full-speed switching with zero additional components in compact portable designs.

FAQ
What is the maximum analog signal voltage the MAX4853ETE can handle?
The MAX4853ETE supports analog signals up to 5.5V - even when VCC is as low as 2.0V - thanks to its over-rail pass-through architecture. This allows 5V USB signals to route cleanly through a 3.3V-powered MAX4853ETE without clamping, distortion, or external protection components. The absolute maximum rating for NO_, COM_, and IN_ pins is -0.3V to +6.0V relative to GND.
Does the MAX4853ETE include a comparator like the MAX4851ETE?
No, the MAX4853ETE does not include a comparator. Pins 2 (CIN) and 11 (COUT) are No Connect (N.C.) in the MAX4853ETE, as confirmed by the pin configuration diagram and selector guide. This distinguishes it from the MAX4851ETE, which integrates a comparator for headphone detection. The MAX4853ETE is optimized purely for analog switching with lower supply current (0.01µA vs. 5µA).
What is the on-resistance mismatch between channels in the MAX4853ETE?
The MAX4853ETE specifies on-resistance match (∆RON) of ≤0.5Ω across temperature (-40°C to +85°C) for the 7Ω switches (Ch2/Ch4) and ≤0.25Ω for the 3.5Ω switches (Ch1/Ch3), measured at VCC = 3V and ICOM = 10mA. This tight matching ensures balanced signal attenuation across parallel paths - critical for differential USB D+/D− integrity and stereo audio channel tracking.
Can the MAX4853ETE be used for USB 2.0 high-speed (480Mbps) applications?
No, the MAX4853ETE is rated for USB 2.0 full-speed (12Mbps) only. Its 150MHz -3dB bandwidth and guaranteed 1ns skew are sufficient for full-speed but insufficient for high-speed USB (480Mbps), which requires >400MHz bandwidth and sub-100ps skew. For high-speed applications, consider dedicated USB 2.0 high-speed switches such as the MAX14533 or similar.
How should the exposed pad (EP) of the MAX4853ETE be connected?
The exposed pad (EP) of the MAX4853ETE must be soldered directly to the PCB ground plane. It serves as both a thermal dissipation path and a low-inductance ground connection for analog and digital sections. Maxim recommends using a 3×3 array of thermal vias under the pad, connected to an internal or bottom-layer ground plane, to maintain junction temperature within limits during continuous operation.
