Functional Features

  • The 74FCT543CTSOG is an octal transparent latch, meaning it can store and output eight bits of data.
  • It features tri-state outputs, allowing the outputs to be disabled or put into a high-impedance state when not in use.
  • The latch is controlled by a clock signal (CLK), which determines when the input data is latched and transferred to the outputs.
  • The Output Enable (OE) pin enables or disables the outputs.

Advantages and Disadvantages

Advantages: - High-speed operation, making it suitable for applications requiring fast data transfer. - Tri-state outputs allow for bus sharing and reduce the number of required control signals. - Compact SOG package offers space-saving benefits.

Disadvantages: - Limited voltage range (4.5V to 5.5V) may restrict compatibility with certain systems. - Propagation delay of 3.5ns may be relatively high for some high-performance applications.

Working Principles

The 74FCT543CTSOG operates based on the principle of transparent latching. When the clock signal (CLK) is active, the input data is latched and transferred to the outputs. The tri-state outputs can be enabled or disabled using the Output Enable (OE) pin. When disabled, the outputs enter a high-impedance state, allowing other devices to drive the shared bus.

Detailed Application Field Plans

The 74FCT543CTSOG is commonly used in various digital systems, including:

  1. Data communication equipment
  2. Networking devices
  3. Microprocessor-based systems
  4. Memory modules
  5. Industrial control systems
