The SP208EET-L/TR is an interface-integrated signal driver from Exar Corporation. It is a two-channel, half-duplex EET transceiver based on the EIA-485 standard, using BiCMOS technology for high performance, low power and low pin-count applications. The SP208EET-L/TR is designed to interface directly with EET systems where point-to-point low speed communications is required. It features fast data rates up to 1Mb/s and low propagation delay of less than 10ns. The SP208EET-L/TR is ideal for industrial and medical applications, such as point-to-point communication between PCs and peripheral devices, or large scale distributed control systems.

The SP208EET-L/TR supports three standard logic levels: RS-422, HSTL and TTL for high speed data transmission and low power logic levels. It is designed to provide a low EMI/RFI interface and is fully compliant with the EIA-485 standard. It also features a wide variety of features that enable users to customize the device for their particular applications. These features include programmable slew rate limiting, loop-back capability and adjustable transmit and receive FIFOs.

The SP208EET-L/TR has two main sections: a transmitter and a receiver. The transmitter takes data from the user-selected logic level and buffers it before feeding it to the bus. The transmitter can be configured for data rates up to 1Mb/s. It also includes programmable slew-rate limiting, loop-back functionality and voltage clamping.

The receiver portion of the SP208EET-L/TR is responsible for receiving data from the bus and converting the data back to the logic levels the user has selected. It includes a receive FIFO for storing the data before it is sent to the user and a transmitter FIFO that is used to store data prior to transmission. The transmitter FIFO can be programmed to operate with different data rates.

The SP208EET-L/TR is also designed to meet the requirements of a wide variety of industrial and medical applications. It has a built-in temperature range of -40C to +85C and a high-accuracy data transfer across the entire temperature range. It also features adjustable power consumption, allowing users to optimize their device for their application. In addition, the SP208EET-L/TR is ESD and EMI/RFI immune, providing reliable performance in harsh operational environments where immunity to surrounding noise is crucial.

The SP208EET-L/TR is a versatile, low pin-count and low power interface device from Exar Corporation that provides a simple, low EMI/RFI solution for low-speed signaling tasks. It is an ideal choice for point-to-point communications in industrial and medical applications. Its fast data rates and adjustable power consumption allows users to easily customize their devices for their particular applications. The SP208EET-L/TR also provides immunity to ESD and EMI/RFI, ensuring reliable performance in harsh operational environments.
