Description

The MAX3344E/MAX3345E USB transceivers convert logic-level signals to USB signals, and USB signals to logic-level signals. An internal 1.5kΩ USB pullup resistor supports full-speed (12Mbps) USB operation. The MAX3344E/MAX3345E provide built-in ±15kV ESD-protection circuitry on the USB I/O pins, D+ and D-, and VCC. The MAX3344E/MAX3345E operate with logic supply voltages as low as 1.65V, ensuring compatibility with low-voltage ASICs. The suspend mode lowers supply current to less than 40µA. An enumerate function allows devices to logically disconnect while plugged in. The MAX3344E/MAX3345E are fully compliant with USB specification 1.1, and full-speed operation under USB specification 2.0. The MAX3344E/MAX3345E have a USB detect that monitors the USB bus for insertion and signals this event. The MAX3344E USB_DET threshold is between 3.6V (min) and 4V (max), while the MAX3345E USB_DET threshold is between 1V (min) and 2.8V (max). The MAX3344E/MAX3345E are available in the miniature 4 x 4 UCSP™, as well as the small 16-pin TSSOP, and are specified over the extended temperature range, -40°C to +85°C.
