The MAX3491EESD is a 1.9 to 5.5V low voltage universal asynchronous receiver-transmitter (UART) with full-duplex capability, offering true logic-level compatibility on all data, control, and handshake signals. It is suitable for applications that require fast setup, regulation of data flow, and enumeration.

The device is designed for IEEE 1394 (firewire) compliant products and applications, including serial communication between two or more low-voltage peripheral components or microcontrollers. The device is ideal for applications that desire minimal power consumption and high performance, especially at low voltage operation, where higher speeds are available with lower power dissipation.

Used as a basic UART, the MAX3491EESD supports six of the most common UART protocols: Start-stop, 8N1, 8O1, 8E1, 6N2, and 7E2. The device also supports data rates of up to 2Mbps, which is sufficient for applications requiring faster data transfer rates. Additionally, the MAX3491EESD is designed to be used as an 8-bit or 16-bit data port and can be integrated into a system for high speed data transfer.

The MAX3491EESD has two main blocks: an 8-pin LED driver and a 6-pin re-driver. The LED driver is used to detect and drive current and can be used on either side of the IC. The 6-pin re-driver is used to reduce noise due to crosstalk and reduces ringing on short traces. This allows the MAX3491EESD to be used on a smaller PCB.

The MAX3491EESD features several other features that aid in its overall operation. One such feature is its Loopback mode, which allows testing of the data lines and receiver logic while eliminating external components. This is a valuable debugging tool and allows the user to quickly isolate faults and verify the integrity of the design. Additionally, the device can be configured with clock stretching and flow control for extra robustness.

The MAX3491EESD\'s power consumption is also quite low when compared to other devices in its class. In active operation, the device consumes close to 30mA of current. When idle, the power consumption drops to a mere 5mA. The MAX3491EESD also incorporates a sleep mode to reduce power consumption even further when the device is not in use.

In summary, the MAX3491EESD is a versatile device providing UART capability for fast, low voltage application. It is designed for IEEE 1394 protocol-compliant products and applications, and features an 8-pin LED driver, a 6-pin re-driver, low power consumption, and clock stretching and flow control options. Its loopback mode offers a valuable debugging tool and the device can be used as an 8-bit or 16-bit data port.
