Product details
Overview
The MAX3341EEUE from Maxim Integrated is a ±15kV ESD-protected USB 1.1/2.0 full-speed (12Mbps) transceiver that converts logic-level signals to USB differential signals and vice versa. It operates with VL as low as 1.8V, features integrated 1.5kΩ USB pullup resistor controlled by ENUM, and includes USB_DET output with 3.7V–4V threshold for host presence detection. Used in cell phones and digital cameras for robust USB interface bridging.
For engineers reviewing the MAX3341EEUE datasheet, MAX3341EEUE pinout, MAX3341EEUE application, or MAX3341EEUE equivalent, key selection considerations include its TSSOP-16 package, suspend-mode current <50µA, internal linear regulator (VTRM = 3.0–3.6V), ±15kV HBM ESD protection on D+/D-/VCC, and USB detect threshold compatibility with 5V USB power rails.
Technical Context
The MAX3341EEUE implements bidirectional level translation between single-ended or differential logic (VL = 1.8V–3.6V) and USB differential signaling (D+/D−), with MODE pin selecting input configuration. Its internal 1.5kΩ pullup resistor connects D+ to VTRM under ENUM control, enabling re-enumeration without power cycle.
USB_DET provides host-voltage detection with fixed 3.7V–4V threshold; SUSP enables low-power mode where RCV goes low but VPI/VMI remain active for wake-up sensing. The device maintains USB skew independence from input skew up to 10ns and supports transmission during suspend at ≤200kbps.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3342EEUE | Identical architecture and pinout, but USB_DET threshold is 1V–2.8V (not 3.7V–4V). | Suitable for systems where USB_DET must trigger at lower VCC (e.g., battery-backed USB ports). | Select MAX3342EEUE only if host-detection voltage threshold must be below 3.7V. |
| SP3243EBCY-L | 3.3V-only VL supply, no internal VTRM regulator, requires external 3.3V rail; ±15kV ESD, TSSOP-28. | Designed for RS-232/USB dual-interface applications; larger footprint and higher pin count. | Choose SP3243EBCY-L only when RS-232 co-integration is required alongside USB. |
Compared with MAX3342EEUE, the MAX3341EEUE provides higher USB_DET threshold for reliable 5V host detection; compared with SP3243EBCY-L, it reduces system BOM by integrating VTRM and supports 1.8V logic, enabling direct interfacing with ultra-low-voltage processors.

FAQ
What is the USB_DET threshold voltage range for MAX3341EEUE?
The MAX3341EEUE USB_DET output asserts high when VCC reaches 3.7V (minimum) and remains asserted up to 4.0V (maximum). This 3.7V–4.0V window ensures reliable detection of standard 5V USB host power while avoiding false triggers from noise or brown-out conditions. The threshold is factory-trimmed and specified over −40°C to +85°C. MAX3341EEUE uses this signal to inform the connected ASIC that a USB host is present and powered.
Does MAX3341EEUE require external resistors on D+ and D− lines?
Yes, MAX3341EEUE requires two 23.7Ω ±1% external resistors - one in series with D+ and one in series with D− - placed between the IC and the USB connector. These resistors set the USB driver output impedance to meet full-speed USB specification requirements (28.5Ω–43.5Ω total including internal contributions). Omitting them causes signal integrity violations and non-compliance with USB electrical standards. MAX3341EEUE's internal circuitry assumes these resistors are present for proper termination and slew rate control.
Can MAX3341EEUE operate with a 1.8V logic supply (VL)?
Yes, MAX3341EEUE fully supports VL from 1.8V to 3.6V, enabling direct interfacing with low-voltage ASICs and microcontrollers. All logic-side I/O (VPO, VMO, VPI, VMI, RCV, MODE, OE, SUSP, ENUM, USB_DET) are VL-referenced and specified across this range. Input thresholds scale with VL (e.g., VIH = 2/3 × VL), and output drive strength is maintained. MAX3341EEUE leverages this capability to eliminate level-shifters in modern portable designs where core logic runs at 1.8V.
How does the ENUM pin function in MAX3341EEUE?
The ENUM pin in MAX3341EEUE controls connection of the internal 1.5kΩ pullup resistor between D+ and VTRM. When ENUM = high, the resistor is connected - enabling USB enumeration per full-speed specification. When ENUM = low, the resistor is disconnected - allowing dynamic reconfiguration of USB communication protocols without cycling power or disconnecting the cable. This feature is unique to MAX3341EEUE and critical for firmware-updatable devices. MAX3341EEUE uses ENUM to maintain USB compliance while supporting field-upgrade scenarios.
What is the maximum supply current for MAX3341EEUE during active USB data transfer?
During active 12Mbps full-speed USB data transfer with CL = 50pF, MAX3341EEUE draws 10mA (minimum) to 20mA (maximum) from VCC. This current includes driver, receiver, and internal regulator overhead. At typical conditions (VCC = 5V, VL = 2.5V, TA = +25°C), ICC is approximately 15mA. MAX3341EEUE specifies this value across temperature and voltage ranges to ensure thermal and power-delivery margin in host-powered applications.
