MAX3390EEUD+T is a dual-channel bidirectional bus transceiver integrated with four I2C / SMBus logic-level translators, four fault-protected I2C / SMBus level-shifters and a fault-protected 4.5V to 5.5V transceiver. The MAX3390EEUD+T is a perfect choice for applications like FPGA and CPLD interfacing as it operates over a wide voltage range and can be used to transmit I2C/SMBus signals up to 400kHz. The integrated low-level logic-level translator helps to level-shift between VTT and regular I2C/SMBus logic levels.

MAX3390EEUD+T has two fault-protected two-channel bus transceivers with integrated low-level logic-level translators, four fault-protected I2C / SMBus-level shifters and two fault-protected 4.5V to 5.5V transceivers. The integrated logic-level translator helps to solve the problem of level-shifting between regular I2C/SMBus logic levels and VTT levels, as well as between 3V, 3.3V and 5V levels (if needed) so the proper levels can be used no matter the voltage levels of the communication bus. The integrated level-shifters allow the outcome of the logic-level translator to be translated back up to the proper I2C/SMBus levels (a.k.a. protocol levels). This enables the transmission of I2C/SMBus signals up to 400kHz.

Moreover, MAX3390EEUD+T can be used to connect two different buses with different voltages (up to 4.5V and 5.5V) without the need for external components. This makes it ideal for applications involving devices with multiple logic levels, such as smart cards and PC cards. It also allows for a combination of 5V and 3V I/Os, eliminating the need for additional level-shifters.

MAX3390EEUD+T includes a thermal protection feature to help protect it from damage caused by excess temperature. This feature is particularly helpful in high temperature applications such as in the automotive and industrial environments. The built-in thermal protection ensures that the device remains functional while avoiding any damage caused by overheat conditions.

In addition, MAX3390EEUD+T is designed with an internal power-on reset circuit, which eliminates the need for an additional reset/enable circuit. This helps save power, design complexity and cost.

MAX3390EEUD+T is ideal for a variety of applications. This includes, but is not limited to, interfacing between FPGAs and CPLDs, level-shifting and bus-extending for I2C/SMBus networks, interfacing between two different buses with varying voltage levels, and connecting devices with multiple logic levels, such as smart cards and PC cards. This integrated bus-transceiver also simplifies level-shifting requirements and eliminates the need for additional level-shifters.

Overall, MAX3390EEUD+T is a great choice for applications that require level-shifting, bus-extending and interfacing between two different busses with varying voltage levels, as it features a wide voltage range, a thermal protection feature, an internal power-on reset circuit, and four I2C/SMBus logic-level translators and four fault-protected I2C/SMBus level-shifters.
