Description

The MAX3346E bidirectional transceiver converts logic-level signals to USB signals, and USB signals to logic-level signals. The MAX3346E includes the 1.5kΩ USB pullup 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 the USB I/O pins, D+ and D-.

The MAX3346E 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. The MAX3346E has an enumerate function that allows devices to logically disconnect while plugged in. The MAX3346E is fully compliant with USB specification 1.1, and the full-speed and low-speed operation under USB specification 2.0.

The MAX3346E is available in the miniature 4 x 4 chip-scale package (UCSP™), as well as the small 14-pin TSSOP, and is rated for the -40°C to +85°C extended temperature range.
