General 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.
