The SN74ACT563DBRE4 is a 16-bit edge triggered D-type flip-flop with 3-state outputs, manufactured by Texas Instruments. It is suited for a wide range of logic applications and is available in both standard and low power versions.

Primary Uses

The SN74ACT563DBRE4 has primary uses in the fields of memory systems, clocking, pulse and signal conditioning, data synchronization, and computer control systems. It is especially suited for cases where high density and flexibility are needed, such as in programmable logic controllers (PLCs).

Features

The device features a powerful logic system consisting of a 16-bit single input latch, a 16-bit output latch, and an integrated output bus. It also comes with integrated static data latching and output flip-flop functionality, making it an ideal choice for a wide range of logic applications. The input and output latches are capable of both synchronous and asynchronous operations, allowing for flexibility in the types of operations that can be performed. It also features a 3-state output buffer, which can be used to create a wide variety of bus topologies.

Working Principle

The SN74ACT563DBRE4 is a static device, meaning that it does not require a continuous electrical power source for operation. When the device is reset, the input latches are set to their low state. To set the output latch, a signal (usually from a clock input) is applied to the input. When the signal is active, the internal logic determines whether the output latch should be set to “0” or “1”, depending on the signal received. The output latch will then remain in the state determined by the signal, until the signal changes. The 3-state output buffer allows the output to be driven to a high impedance state, so that multiple devices can share the same bus.

Application Examples

The SN74ACT563DBRE4 can be used in a variety of applications, such as memory systems, clocking, pulse and signal conditioning, and computer control systems. It is well-suited for programmable logic controllers, as it can be used to handle the complex data manipulations needed in the operation of these systems. It can also be used to extend the capability of existing latches, such as by allowing one to be connected to multiple data sources. Finally, it can be used to provide a means of synchronization between multiple device latches, ensuring that data is read at the same time.

Conclusion

The SN74ACT563DBRE4 is an extremely versatile component, with applications in memory, clocking, and computer control systems. It is well-suited for use in programmable logic controllers, and can be used to extend the capability of existing latches. It is a static device, requiring no power for operation, and featuring a 3-state output buffer for enhanced flexibility. With its wide range of possible uses, the SN74ACT563DBRE4 is an incredibly valuable resource for system designers.
