MAX3346E Datasheet | Maxim Integrated

Description The MAX3346E bidirectional transceiver converts logiclevel signals to USB signals, and USB signals to logiclevel 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 ±15k V 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 patibility 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 pliant 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 chipscale package (UCSPTM), as well as the small 14-pin TSSOP, and is rated for the -40°C to +85°C extended temperature range.
