Functional Features

The SN74ACT563NSR is an octal D-type transparent latch with 3-state outputs. It is designed to store and transfer data in digital systems. The latch is transparent, meaning that the input data is directly transferred to the output when the latch enable (LE) signal is high. The latch also features 3-state outputs, allowing the outputs to be disabled or put into a high-impedance state when the output enable (OE) signal is low.

Advantages and Disadvantages

Advantages: - High-speed operation - Wide operating voltage range - 3-state outputs for bus-oriented applications - Compact SOIC package for space-saving designs

Disadvantages: - Limited number of bits (8) - Not suitable for applications requiring higher bit counts

Working Principles

The SN74ACT563NSR works by latching the input data when the latch enable (LE) signal is high. When the clock (CLK) signal transitions from low to high, the input data is transferred to the outputs. The latch remains transparent as long as the LE signal is high. The output enable (OE) signal controls the 3-state outputs, allowing them to be enabled or disabled.

Detailed Application Field Plans

The SN74ACT563NSR can be used in various digital logic applications, including but not limited to: - Data storage and transfer in microprocessors - Address decoding in memory systems - Bus interface control in communication systems - State machine implementation in control systems
