±15kV ESD-Protected USB Level Transceivers in UCSP with USB Detect

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 USBDET threshold is between 3.7V (min) and 4V (max), while the MAX3342E USBDET 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.
