MAX3341E

±15kV ESD保护、USB收发器,UCSP封装,带有USB检测


点击查看特定型号的库存状况。

说明

The MAX3341E/MAX3342E USB transceivers convert logic-level signals to USB signals, and USB signals to logic-level signals. An internal 1.5k? USB termination resistor supports full-speed (12Mbps) USB operation. The MAX3341E/MAX3342E provide built-in ±15kV ESD-protection circuitry on the USB I/O pins, D+ and D-, and VCC.

The MAX3341E/MAX3342E operate with logic supply voltages as low as 1.8V, ensuring compatibility with low-voltage ASICs. The suspend mode lowers supply current to less than 50µA. A unique enumerate feature allows changes in USB communication protocol while power is applied. The MAX3341E/MAX3342E are fully compliant with USB specification 1.1, and full-speed operation under USB specification 2.0.

The MAX3341E/MAX3342E have a USB detect that monitors the USB bus for insertion and signals this event. The MAX3341E USB_DET threshold is between 3.7V (min) and 4V (max), while the MAX3342E USB_DET threshold is between 1V (min) and 2.8V (max).

The MAX3341E/MAX3342E are available in the miniature 4 5 4 UCSP™, as well as the small 16-pin TSSOP, and are specified over the extended temperature range, -40°C to +85°C.
