USB 2.0 half-duplex transceiver for 12 Mbps links
The Maxim Integrated MAX3456EETE+ is a single-channel half-duplex transceiver supporting the USB 2.0 protocol at a data rate of 12 Mbps. The device operates from a 3V to 3.6V supply and is specified over the industrial temperature range of -40°C to 85°C, making it suitable for equipment that sees outdoor or factory-floor conditions.
Supply rail and signal integrity
The 3V to 3.6V supply range ties this transceiver to a 3.3V nominal rail, which is common in mixed-voltage systems with an FPGA, MCU, or USB hub controller. The receiver hysteresis of 250 mV provides noise immunity on the USB differential pair, reducing the risk of false triggering on a lossy cable run or in an electrically noisy environment. For a BOM fit, confirm the system's 3.3V rail stays within the 3V to 3.6V window under load — a 3.0V LDO with tight tolerance is fine; a 2.5V rail is not.
