Maxim MAX3349E USB Transceiver Datasheet
The MAX3349E is a full‑speed USB 2.0 transceiver that also supports a UART multiplexing mode, allowing external UART signals to be routed to the USB D+ and D‑ lines. It provides ±15 kV ESD protection, internal series termination, a 1.5 kΩ pull‑up on D+, and a separate UART voltage supply for legacy devices.
Key specifications include operation from –40 °C to +85 °C, a maximum UART baud rate of 921 kbaud, VBUS input range of 3.0 V‑5.5 V, and availability in 16‑pin TQFN (4 mm × 4 mm) and 16‑bump UCSP (2 mm × 2 mm) packages.
