  • Outputs can be disabled by setting the output enable (OE) signal low
  • High-speed operation and low power consumption due to CMOS technology

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer - Low power consumption helps in reducing overall system energy requirements - Wide operating voltage range provides flexibility in different applications - 3-state outputs allow for bus sharing and easy interfacing with other devices

Disadvantages: - Limited output drive capability may restrict its use in certain high-current applications - Propagation delay of 13ns may not be suitable for ultra-high-speed systems

Working Principles

The 74HCT573DB,118 operates as an octal D-type transparent latch. When the latch enable (LE) signal is high, the data inputs (D0-D7) are latched to the outputs (Q0-Q7). The latch holds the data until a new set of inputs is provided. The output enable (OE) signal can be used to disable the outputs, allowing for bus sharing or tri-state operation.

Detailed Application Field Plans

The 74HCT573DB,118 is commonly used in various digital systems where temporary storage and data transfer are required. Some application fields include:

  1. Microprocessor-based systems
