Product Description

The SN74AC563DWR is designed to store data that is inputted when the latch-enable (LE) input is high. The data is retained when LE is taken low. The device provides a convenient way to interface with bus-oriented systems because of its output-enable (OE) feature. When OE is low, the eight outputs are active and reflect the data that has been latched. When OE is high, the outputs are in a high-impedance state, which is ideal for connecting multiple outputs to a bus without the risk of bus contention.

With its wide operating voltage range and the ability to drive up to 24 mA at the outputs, this latch is suitable for interfacing with a wide range of other digital components. Additionally, the SN74AC563DWR offers edge-rate control circuitry that significantly improves noise immunity when used in a typical system environment.

Common applications for the SN74AC563DWR include buffer storage, memory address latching, and data transmission systems where it is necessary to isolate the input from the output. Its robustness and reliability make it a preferred choice for complex digital systems that require stable and consistent performance.

Overall, the SN74AC563DWR is a versatile and reliable component that provides high-speed latching capabilities with the added benefit of three-state outputs for bus-oriented systems.
