Maxim MAX3346E USB Bidirectional Transceiver Datasheet
The MAX3346E converts logic‑level signals to USB signals and vice‑versa. It includes an internal 1.5 kΩ pull‑up resistor, a linear regulator that provides a 3.3 V output, and a logic‑selectable suspend mode that reduces current draw to under 40 µA.
The device operates from 1.65 V to 3.6 V on the system side and from 4.0 V to 5.5 V on the USB side, supporting both full‑speed (12 Mbps) and low‑speed (1.5 Mbps) USB specifications. It is offered in a 4 × 4 mm UCSP package and a 14‑pin TSSOP package, and is rated for –40 °C to +85 °C operation.
