ANALOG DEVICES MAX3344EEUE+ ESD-Protected USB Transceiver

MAX3344EEUE+ is a ±15kV ESD-protected USB transceiver with USB detect in a 16 pin TSSOP package. The USB transceiver converts logic-level signals to USB signals, and USB signals to logic-level signals. An internal 1.5k? USB pullup resistor supports full-speed (12Mbps) USB operation. The MAX3344E provides built-in ±15kV ESD-protection circuitry on the USB I/O pins, D+ and D-, and VCC. The MAX3344E operates 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 is fully compliant with USB specification 1.1, and full-speed operation under USB specification 2.0. The MAX3344E has 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).

• Enumerate input�allows USB connection through software
• Allow single-ended or differential logic I/O
• Internal linear regulator allows direct powering from the USB
• Internal pullup resistor for full-speed operation
• Three-state outputs
• No power-supply sequencing required
• Driver active in suspend mode
• Temperature range from -40°C to +85°C
