Product details
Overview
The MAX14510EEVB+T from Maxim Integrated is a USB 2.0 Hi-Speed and audio DPDT analog switch with VBUS detection, enabling automatic path selection between USB and AC-coupled audio signals. It operates from +2.7V to +5.0V, delivers 950MHz -3dB bandwidth, 2.4Ω typical on-resistance, and supports analog signal swings down to VCC − 5.0V-used in smartphone docking interfaces requiring seamless USB/audio source switching.
For engineers reviewing the MAX14510EEVB+T datasheet, MAX14510EEVB+T pinout, MAX14510EEVB+T application, or MAX14510EEVB+T equivalent, this page provides verified functional context, validated pin roles, confirmed fault-protection behavior (+5.5V COM protection), VBUS-triggered auto-switching logic, and real-world audio/USB coexistence design constraints.
Technical Context
The MAX14510EEVB+T implements a dual-pole, double-throw (DPDT) architecture with independent control of two bidirectional signal paths (COM1/COM2 ↔ ANO1/UNC1 and COM2/COM2 ↔ ANO2/UNC2). Its internal charge pump generates a negative supply to pass analog signals below ground without clipping, activated only when EN = high and COM voltage remains below fault threshold VFP.
VBUS detection (VB input) triggers automatic switching to the USB path (UNC_ → COM_) when VVB ≥ VVBDET (VCC + 0.2V to VCC + 1.0V); AOR input overrides VB control-driving AOR low enables VB-based selection, while driving AOR high forces audio path (ANO_ → COM_), eliminating external logic for mode arbitration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | +2.7V to +5.0V - single-supply operation compatible with Li-ion battery and USB VBUS rails. |
| -3dB Bandwidth | 950MHz (typ) - preserves USB 2.0 Hi-Speed eye integrity and wideband audio fidelity up to 20kHz. |
| On-Resistance (RON) | 2.4Ω (typ) - minimizes insertion loss and THD+N degradation in audio paths (0.05% measured). |
| COM Fault Protection | +5.5V tolerance on COM1/COM2 - meets USB 2.0 fault-protection specification and prevents downstream transceiver damage. |
| VBUS Detection Threshold | VCC + 0.2V to VCC + 1.0V - ensures reliable USB presence detection across full supply range and temperature (-40°C to +85°C). |
| Shunt Resistor Value | 100Ω to 200Ω - discharges ANO_ node capacitance during path transitions to suppress audible click-and-pop. |
| ESD Rating (COM pins) | ±15kV HBM - withstands handling and system-level ESD events without latch-up or parametric shift. |
Pinout & Package
MAX14510EEVB+T is housed in a 10-pin Ultra-Thin QFN (UTQFN) package measuring 1.4mm × 1.8mm, with 0.4mm pitch and exposed thermal pad. Pin 1 is marked by top-side laser etch "AAJ".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 UNC1 | USB Input 1 (normally closed) | Connects to COM1 when VB > VVBDET; carries Hi-Speed USB D+/D− signals with <8pF off-capacitance. |
| 2 ANO2 | Audio Input 2 (normally open) | AC-coupled audio path terminal supporting VCC − 5.0V to VCC swing; includes internal 100–200Ω shunt for pop suppression. |
| 3 ANO1 | Audio Input 1 (normally open) | Primary audio channel input; same negative-swing capability and shunt as ANO2; matched RON ≤ 0.2Ω vs. ANO2. |
| 4 GND | Ground reference | Common return for analog, digital, and charge-pump circuits; must connect directly to low-impedance PCB ground plane. |
| 5 VCC | Positive supply input | +2.7V to +5.0V power rail; requires local 0.1µF ceramic bypass capacitor placed within 1mm of pin. |
| 6 COM1 | Common terminal, Switch 1 | Bidirectional I/O shared between UNC1 and ANO1; fault-protected to +5.5V; supports ±100mA continuous current. |
| 7 COM2 | Common terminal, Switch 2 | Identical functionality to COM1; independent fault protection and signal routing; enables dual-path USB/audio multiplexing. |
| 8 AOR | Audio Override Input | Active-low control: AOR = low enables VB-driven auto-switching; AOR = high forces ANO_ → COM_ path regardless of VB state. |
| 9 VB | VBUS Detection Input | Analog comparator input monitoring USB VBUS; triggers automatic UNC_ → COM_ connection when VB ≥ VVBDET (VCC + 0.2V to +1.0V). |
| 10 UNC2 | USB Input 2 (normally closed) | Second USB differential pair input; identical electrical specs to UNC1; enables full USB 2.0 data lane switching. |
Key Features
| Feature | Design Value |
|---|---|

| Integrated click-and-pop suppression | 100–200Ω internal shunt resistors discharge ANO1/ANO2 node capacitance during path transitions, measurably reducing audible artifacts in portable audio systems. |
| +5.5V COM fault protection | Hardware-enforced overvoltage cutoff protects downstream USB transceivers from hot-plug transients and cable ESD events per USB 2.0 spec. |
| ±15kV HBM ESD on COM pins | Robust front-end protection allows direct integration into handheld device connectors without additional TVS diodes or layout derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB/audio analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX14508EEVB+ | Uses EN/CB control instead of VB/AOR; lacks VBUS detection; includes enable input for shutdown mode. | Suitable for manually controlled USB/audio mux where microcontroller GPIO drives CB and EN; no auto-detection capability. | Select MAX14508EEVB+ when deterministic software-controlled switching is required and VBUS sensing is unnecessary. |
| MAX14511EEVB+ | Same VB/AOR architecture as MAX14510EEVB+T but omits internal shunt resistors on ANO1/ANO2. | Applicable where click-and-pop is mitigated externally (e.g., via mute sequencing or external RC networks). | Choose MAX14511EEVB+ when board space is constrained and external pop suppression is already implemented. |
Compared with MAX14508EEVB+ and MAX14511EEVB+, the MAX14510EEVB+T uniquely combines VBUS-triggered auto-switching, internal shunt-based pop suppression, and full USB 2.0 fault protection-making it optimal for consumer docking and adapter designs requiring zero-firmware mode arbitration and clean audio transitions.

FAQ
What is the function of the AOR pin on the MAX14510EEVB+T?
The AOR (Audio Override) pin on the MAX14510EEVB+T controls whether VBUS detection governs path selection. When AOR is driven low, the VB input determines switching (UNC_ → COM_ if VVB ≥ VVBDET). When AOR is high, the switch defaults to the audio path (ANO_ → COM_) regardless of VB state-enabling manual override without firmware intervention. This behavior is confirmed in the MAX14510E truth table and functional diagram.
Does the MAX14510EEVB+T support analog signals below ground?
Yes, the MAX14510EEVB+T supports analog signals as low as VCC − 5.0V on ANO1 and ANO2 terminals due to an internal charge pump that generates a negative supply rail. This capability is active only when EN is high and COM voltage remains below the fault-protection threshold VFP. The feature enables distortion-free transmission of AC-coupled audio signals without external negative supplies-verified in the Absolute Maximum Ratings and Detailed Description sections.
What is the maximum fault voltage the COM pins tolerate on the MAX14510EEVB+T?
The COM1 and COM2 pins of the MAX14510EEVB+T tolerate up to +5.5V continuously, as specified in the Absolute Maximum Ratings and confirmed in the Fault Protection section. This rating ensures compliance with the USB 2.0 fault-protection specification and protects downstream transceivers during hot-plug events or cable-induced transients. Operation above this voltage risks permanent damage.
How does the MAX14510EEVB+T reduce audio click-and-pop noise?
The MAX14510EEVB+T reduces audio click-and-pop noise using integrated 100Ω to 200Ω shunt resistors on the ANO1 and ANO2 terminals. These resistors automatically discharge residual capacitance at the ANO_ nodes when the switch disconnects from COM_, preventing voltage spikes that cause audible transients. This mechanism is explicitly documented in the Benefits and Features list and Electrical Characteristics table under "Shunt Switch Resistance."
Is the MAX14510EEVB+T pin-compatible with other devices in the MAX14508E–MAX14511E family?
No, the MAX14510EEVB+T is not pin-compatible with MAX14508EEVB+ or MAX14509EEVB+ due to differing control pin assignments: MAX14510EEVB+T uses VB and AOR (pins 9 and 8), whereas MAX14508EEVB+ uses EN and CB (pins 9 and 8). Pin mapping is confirmed in the Pin Configurations diagram and Pin Description table-substitution requires PCB layout revision.
