Product details
Overview
MAX4853HETE from Maxim Integrated is a quad SPST analog switch with over-rail high-impedance mode, 3.5Ω/7Ω channel on-resistance, 150MHz -3dB bandwidth, and 1.8V logic compatibility - designed for USB 2.0 full-speed (12Mbps) signal routing in portable audio and data interfaces.
For engineers reviewing the MAX4853HETE datasheet, MAX4853HETE pinout, MAX4853HETE application, or MAX4853HETE equivalent, this device supports rail-to-rail analog switching up to 5.5V with supply as low as +2V, delivers sub-1ns skew for D+/D− USB paths, and enables robust signal isolation during over-voltage events without distortion or latch-up.
Technical Context
The MAX4853HETE implements four independent SPST switches with asymmetric on-resistance: channels 1 and 3 use 3.5Ω switches; channels 2 and 4 use 7Ω switches. It operates from a single +2V to +5.5V supply and enters high-impedance mode when input signals exceed VCC - unlike the pass-through behavior of MAX4853 variants.
This high-impedance over-rail response is implemented via internal voltage-sensing circuitry that disables conduction above VCC, ensuring signal integrity and preventing backdrive in mixed-supply systems. The device features 30pF COM on-capacitance (7Ω channels) and 40pF NO off-capacitance, optimized for low crosstalk (-95dB) and minimal charge injection (8pC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +5.5V - supports direct interface with 1.8V/3.3V/5V logic and analog sources without level shifters. |
| On-Resistance (Ch1/Ch3) | 3.5Ω max at VCC = 3V, TA = +85°C - ensures <0.5% signal attenuation for 600Ω audio loads and low insertion loss in USB paths. |
| On-Resistance (Ch2/Ch4) | 7Ω max at VCC = 3V, TA = +85°C - balances low capacitance and power handling for differential data lines. |
| -3dB Bandwidth | 150MHz - fully supports USB 2.0 full-speed (12Mbps) eye diagram compliance with margin. |
| Logic Compatibility | 1.8V input threshold - enables direct control from low-voltage microcontrollers without pull-ups or translators. |
| Leakage Current | ±10nA max (TA = -40°C to +85°C) - preserves signal fidelity in high-impedance sensor or audio bias networks. |
| Switching Time (tON/tOFF) | 100ns/60ns max (TA = -40°C to +85°C) - meets USB timing budgets for hot-plug detection and dynamic reconfiguration. |
Pinout & Package
MAX4853HETE is housed in a 16-pin, 3mm × 3mm thin QFN package with exposed thermal pad (EP), rated for -40°C to +85°C operation. Pin 1 is marked by a dot or notch; pin numbering follows JEDEC MO-220 standard, counterclockwise from top-left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 7, 10, 12, 16 | NO1, NO2, NO3, NO4, COM4, COM1 | Analog switch terminals - bidirectional; NOx open when INx = low; COMx connects to NOx when INx = high. |
| 3, 9, 13, 15 | IN1, IN2, IN3, IN4 | Digital control inputs - accept 0V to VCC or up to +5.5V; 1.8V-compatible thresholds enable mixed-supply control. |
| 6 | GND | Ground reference for analog and digital domains - must be connected to system ground; EP also tied to GND. |
| 14 | VCC | Single positive supply input - requires local 0.01µF ceramic bypass capacitor to GND for noise suppression. |
| 2, 11 | N.C. | No internal connection - left floating; not bonded or routed on die (confirmed for MAX4853H variant). |
Key Features
| Feature | Design Value |
|---|---|
| Over-rail high-impedance mode | Input signal > VCC forces switch into Hi-Z state - prevents backfeeding and protects downstream circuitry without clamping diodes. |
| Asymmetric channel configuration | Ch1/Ch3: 3.5Ω low-RON for critical analog paths; Ch2/Ch4: 7Ω higher-RON for lower capacitance in high-speed data lanes. |
| Sub-1ns channel skew | 0.1ns typical skew (RS = 39Ω, CL = 50pF) - maintains D+/D− signal alignment essential for USB 2.0 eye mask compliance. |
| Ultra-low leakage | ±10nA max off-leakage and on-leakage - avoids DC offset drift in precision audio bias networks and sensor interfaces. |
| 1.8V logic compatible inputs | VIH = 1.4V min at VCC = 2.0V - enables direct drive from low-power MCUs and PMICs without external level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4853ETE | Same pinout and package; uses pass-through over-rail mode instead of high-impedance mode. | Suitable where over-voltage signals must pass unattenuated (e.g., legacy USB hubs), not where isolation is required. | Select MAX4853ETE only if system design mandates signal continuity above VCC; otherwise MAX4853HETE provides superior fault containment. |
| TS3USB30E | 3-channel USB switch; 6Ω RON; 200MHz bandwidth; no over-rail handling; requires external VDD control. | Limited to 3-switch configurations; lacks high-impedance response to over-voltage - unsuitable for mixed-rail safety-critical paths. | Choose TS3USB30E only for cost-sensitive 3-channel designs without over-rail requirements; MAX4853HETE remains preferred for 4-channel + safety. |
Compared with MAX4853ETE and TS3USB30E, MAX4853HETE uniquely combines quad-channel count, asymmetric RON optimization, and deterministic high-impedance over-rail response - making it the only option for compact, safety-aware USB/audio multiplexing in space-constrained portable designs.

FAQ
What is the over-rail behavior of MAX4853HETE compared to MAX4853ETE?
The MAX4853HETE enters high-impedance mode when analog input exceeds VCC, blocking signal flow to protect downstream circuitry. In contrast, MAX4853ETE passes over-rail signals through without attenuation. This makes MAX4853HETE ideal for fault-tolerant USB/audio routing where voltage domain isolation is critical - a key differentiator confirmed in the datasheet's "Over-Rail Handling" selector guide.
Does MAX4853HETE support USB 2.0 full-speed (12Mbps) without signal degradation?
Yes. MAX4853HETE guarantees 150MHz -3dB bandwidth and <1ns channel skew (typical 0.1ns), both measured under USB-compliant conditions (RS = 39Ω, CL = 50pF). Its 3.5Ω/7Ω on-resistance and 30pF COM on-capacitance ensure minimal insertion loss and jitter accumulation - directly validated in Figure 2 and Table "Dynamic Characteristics" of the MAX4853HETE datasheet.
Can MAX4853HETE be controlled by a 1.8V microcontroller?
Yes. MAX4853HETE accepts 1.8V logic levels: VIH is 1.4V min at VCC = 2.0V and 1.8V min at VCC = 3.6V–5.5V. Its inputs tolerate up to +5.5V regardless of VCC, enabling direct interface with 1.8V GPIOs without level shifters - a feature explicitly specified in the "Digital I/O (IN_)" section of the electrical characteristics table.
What is the maximum analog signal range supported by MAX4853HETE?
MAX4853HETE supports analog signals from 0V to +5.5V - independent of VCC, which can be as low as +2.0V. This rail-to-rail capability is enabled by its proprietary over-rail architecture and confirmed in the "Analog Signal Range" parameter (VNO_, VCOM_ = 0 to 5.5V) across all operating temperatures in the datasheet's Electrical Characteristics tables.
Is the exposed thermal pad (EP) of MAX4853HETE required to be grounded?
Yes. The exposed pad (EP) must be soldered to a PCB ground plane per Maxim's package drawing T1633-1 and Pin Description table. It serves as both thermal dissipation path and electrical ground reference; leaving it unconnected degrades thermal performance and may cause instability. This requirement is explicitly stated in the "Pin Configurations" section and package outline notes.
