The 74VCX16244GX device is a highly-integrated logic device belonging to the category of logic devices known as Buffers, Drivers, Receivers and Transceivers. This device is designed to perform data transmission between multiple buses. The device is capable of data transmission between two systems where one is typically operating within the 3.3V voltage domain, and the other is residing within the 5V voltage domain. The device is also able to provide bus communication between signals from different systems operating at different speeds, such as burst communication and handshake communication. The 74VCX16244GX is specifically designed for applications utilizing the IEEE-1284 parallel bus protocol. The device is able to support the bidirectional transfer of information, including the synchronization and resynchronization of various features of the protocol.

The 74VCX16244GX is designed to support data transfer between two banks of 8 data lines and one combination of control lines. Additionally, the device is also capable of routing data between two systems or buses as well as providing line buffering to support mode selection and also to ensure that data output is ready in both directions. The device’s logic architecture allows it to be used in a variety of application scenarios, such as network data interfaces, controller peripherals, embedded systems, or data acquisition. It is designed to handle data rate of up to 33 MHz.

The working principle of the 74VCX16244GX is based on its on-chip bidirectional capability. When the device is configured as a bidirectional programmable I/O, it can function as either a transfer register or a logic-level buffer. In the event that the 74VCX16244GX is configured to function as a transfer register, it will couple two buses together in the same fashion as other parallel I/O devices. Alternatively, when the device is configured as a logic-level buffer, it will isolate the two buses from each other, allowing the signals from each bus to maintain their individual characteristics. Furthermore, when the device is configured in the logic-level buffer mode, it is able to perform level conversion between the two buses, allowing the device to accommodate signals from different voltage domains.

The 74VCX16244GX is a further integration of the bidirectional data transfer solutions by providing two transfer registers, one for data input and one for data output. The device also provides one combination control line to enable various features as well as for direction control for the data transfer. Additionally, the device also provides a control signal bus which is used to synchronize clock signals from the host and target devices.

In the event of an error on one of the buses or during data transfer, the 74VCX16244GX provides a signal which may be used to diagose the error and facilitate its correction. Lastly, the device is able to provide data protection by automatically shielding buses from potential harmful portions of signals and also by supporting bidirectional static signal control.

In summary, the 74VCX16244GX device is a highly-integrated logic device belonging to the Buffers, Drivers, Receivers, Transceivers category. The device is designed to perform data transmission between multiple buses, and is capable of data transmission between two systems operating within different voltage domains. The device is specifically designed for applications utilizing the IEEE-1284 parallel bus protocol, and is also able to provide line buffering to support mode selection, as well as data protection features. The device’s logic architecture and features make it suitable for a variety of application scenarios.
