点击查看特定型号的库存状况。

说明

The MAX3340E/MAX3343E bidirectional level translators convert logic-level signals to USB signals, and USB signals to logic-level signals. They include the 1.5kΩ USB termination resistor internally, and support both full-speed (12Mbps) and low-speed (1.5Mbps) USB operation. They have built-in ±15kV ESD protection circuitry to guard the USB I/O pins, D+ and D-.

The MAX3340E/MAX3343E operate with VL at voltages as low as 1.8V, ensuring compatibility with low-voltage ASICs. The MAX3340E/MAX3343E feature a logic- selectable suspend mode that lowers current draw to less than 200µA. The MAX3340E/MAX3343E have a unique reenumerate feature that allows changes in USB communication protocol while the power is on. The MAX3340E/MAX3343E are fully compliant with USB specification 1.1, and the full-speed and low-speed operation under USB specification 2.0.

The MAX3340E/MAX3343E are available in the miniature 4 x 4 chip-scale package, as well as the small 14-pin TSSOP, and are rated for the -40°C to +85°C extended temperature range.
