  • Latch Enable (LE) input allows data to be entered into the flip-flops
  • Clock (CLK) input controls the latching action
  • Output Enable (OE) input enables/disables the outputs
  • 3-state outputs allow multiple devices to be connected to a common bus

Advantages and Disadvantages

Advantages: - High-speed operation - Wide supply voltage range - 3-state outputs for bus sharing applications - Small package size for space-constrained designs

Disadvantages: - Limited number of inputs and outputs - Not suitable for high-power applications

Working Principles

The SN74AC563NSRE4 is an octal latch that stores data using D-type flip-flops. When the Latch Enable (LE) input is high, the data on the Data Inputs (D0-D7) is transferred to the outputs (Q0-Q7) on the rising edge of the Clock (CLK) input. The Output Enable (OE) input controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74AC563NSRE4 can be used in various digital systems where storage of data is required. Some potential application fields include:

  1. Microcontrollers and microprocessors
