MAX13342E Datasheet | Maxim Integrated

Description The MAX13342E/MAX13345E USB-pliant transceivers are designed to minimize the area and external ponents required to interface low-voltage ASICs to USB. The devices ply 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 ±15k V 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 patibility 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.
