The MAX13342E/MAX13345E USB-compliant transceivers are designed to minimize the area and external components required to interface low-voltage ASICs to USB. The devices comply with USB 2.0 specification for full-speed-only (12Mbps) operation. The transceivers include an internal 3.3V regulator, an internal 1.5kΩ D+ pullup resistor, and built-in ±15kV ESD protection circuitry to protect the USB I/0 ports (D+,D-). The MAX13345E also has internal series resistors, allowing it to be wired directly to a USB connector. These devices operate with logic-supply voltages as low as +2.3V, ensuring compatibility with low-voltage ASICs. A low-power mode reduces current consumption to less than 45µA. An enumerate function controls the D+ pullup resistor, allowing devices to logically disconnect while remaining plugged in. The MAX13342E has controlled output impedance of 2Ω (max) on D+/D-, allowing the use of external switches to multiplex two different USB devices onto a single USB connector. The MAX13345E has 43.5Ω (max) internal resistors on D+/D- for direct connection to the USB connector. The MAX13342E/MAX13345E are equipped with DAT and SE0 interface signals. These transceivers provide a USB detection function that monitors the presence of USB VBUS and signals the event. These devices operate over the extended -40°C to +85°C temperature range and are available in UCSP™ 2.0mm x 1.5mm and 14-pin TDFN (3mm x 3mm) packages. UCSP™ is a trademark of Maxim Integ
The MAX13342E and MAX13345E are full‑speed (12 Mbps) USB‑compliant transceivers designed to minimize board area and external components when interfacing low‑voltage ASICs. They include an internal 3.3 V regulator, a 1.5 kΩ D+ pull‑up resistor, ±15 kV ESD protection, and optional internal series resistors for direct USB connector attachment.
The devices operate from a VBUS of 4.0‑5.5 V and a logic supply (VL) of 2.3‑3.6 V, with a regulated 3.3 V output (VTRM). They support low‑power mode (current <45 µA) and provide USB VBUS detection, DAT/SE0 3‑wire interface, and configurable operation modes (normal, suspend, sharing, disable). Available in UCSP 2.0 mm×1.5 mm and 14‑pin TDFN 3 mm×3 mm packages.
