The 74FR244SJX is a low-power, hex-buffered bidirectional transceiver designed to handle data, control, and address signals. It features separate output enables (OE) for each of the 3-state buffers which allows the user to directly control the output or to latch it with one of the inputs. The device is able to intake and output 24 different signals, with 8 inputs and 8 outputs, making it perfect for efficient switching applications.

Application Field

The 74FR244SJX is most commonly used in applications such as computer buses, data transmission links, high speed data enable/disable circuits, clock systems, data multiplexers and collectors, high speed video enable/disable circuits, and communications links. Regardless of the application, the device is designed to handle inputs and outputs in reliable manner.

Working Principle

The 74FR244SJX transceiver functions by allowing the user to program external logic to control the input and output of the signals sent through the device. An internal buffer allows for consolidation of the signals to be outgoing and incoming, enabling multiple signals to be sent through the device simultaneously. Through the application of select control signals, the device can be brought into an active state, where the internal logic of the device is enabled and signals sent to the device are interpreted by the device. In active state, the data received by the device is directed to the appropriate output, and the data output from the device is directed to the desired signal. The device also features a tri-state output configuration, allowing for the user to assign the output state which best suits the needs of their application.

The device can alternate between the active state and the inactive state, allowing the user to cycle through multiple signals through the device. When the device is in the inactive state, signals being sent or received by the device will remain in the state they were in prior to the device entering the inactive state. The inputs of the device can be latched with one of the outputs of the device, allowing the application using the device to maintain its current state even when the device is switched to an inactive state.

Conclusion

The 74FR244SJX is a highly efficient and reliable transceiver, making it an ideal choice for applications which require data, control and address signal transmission. With its 8 inputs and 8 outputs, it can be used to efficiently handle multiple signals simultaneously. It also features tri-state output configurable, allowing for the user to program the necessary output state for their application. The device can also easily alternate between active and inactive states, allowing for a smooth transition from one signal to another. With its reliability and efficiency, the 74FR244SJX is the perfect choice for reliable and efficient data management.
