Maxim MAX3346E Manuals

The MAX3346E is a bidirectional transceiver that converts logic-level signals to USB signals, and USB signals to logic-level signals. It includes an internal 1.5kΩ USB pullup resistor and supports both full-speed (12Mbps) and low-speed (1.5Mbps) USB operation. The device features built-in ±15kV ESD protection circuitry for the USB I/O pins, D+ and D-. It operates with VL voltages as low as 1.65V, ensuring compatibility with low-voltage ASICs. The MAX3346E has a logic-selectable suspend mode that reduces current draw to less than 40µA. It also has an enumerate function that allows devices to logically disconnect while plugged in. The MAX3346E is fully compliant with USB specification 1.1 and supports full-speed and low-speed operation under USB specification 2.0. It 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.

Introduces the working principle, features and applications of MAX3346E bidirectional transceiver. MAX3346E is a USB transceiver that supports full-speed and low-speed USB communication, has an internal 1.5kΩ USB pull-up resistor, supports logic-selectable suspend mode, and operates at a voltage range of 1.65-5.5V.
