Functional Features

• Octal D-Type Transparent Latch: The SN74ACT563DBRG4 provides eight individual transparent D-type latches, allowing for easy storage and retrieval of data.
• 3-State Outputs: Each latch has a 3-state output, which enables the user to control whether the output is actively driving the signal or in a high-impedance state.
• Latch Enable (LE) and Output Enable (OE): The LE pin controls the latching function, while the OE pin enables or disables the outputs.

Advantages and Disadvantages

Advantages: - High operating frequency allows for fast data processing. - 3-state outputs provide flexibility in controlling the signal flow. - Compact package size saves board space.

Disadvantages: - Limited voltage supply range (2 V to 6 V). - Propagation delay time may affect timing-sensitive applications.

Working Principles

The SN74ACT563DBRG4 operates by latching the input data when the latch enable (LE) signal is high. When the output enable (OE) signal is also high, the latched data is available at the outputs. If the OE signal is low, the outputs are in a high-impedance state, effectively disconnecting them from the circuit.

Detailed Application Field Plans

The SN74ACT563DBRG4 can be used in various digital logic applications, including but not limited to: - Data storage and retrieval systems - Address decoding circuits - Bus interface units - Register banks - Memory modules
