The MAX3346EEUD+ is a ±15kV ESD-protected USB transceiver in 14 pin TSSOP package. This bidirectional transceiver converts logic level signals to USB signals and USB signals to logic level signals. It includes 1.5Kohm USB pull-up resistor internally and supports both full speed (12Mbps) and low speed (1.5Mbps) USB operation. The device has built-in ±15kV ESD protection circuitry to guard USB I/O pins, D+ and D-. It operates with VL voltages as low as 1.65V ensuring compatibility with low voltage ASICs. The device features a logic selectable suspend mode that lowers current draw to less than 40μA. It has an enumerate function that allows device to logically disconnect while plugged in. It is fully compliant with USB specification 1.1 and full speed and low-speed operation under USB specification 2.0. It is used in cell phones, PC peripherals, data cradles, PDAs and MP3 players.
