Functional Features

The CD74HCT573M is an octal transparent D-type latch with 3-state outputs. It is designed to store and transfer data in digital systems. The latch can be enabled or disabled using the Latch Enable (LE) pin, and the outputs can be enabled or disabled using the Output Enable (OE) pin. When the latch is enabled, the data inputs are transferred to the outputs. The 3-state outputs allow multiple devices to share a common bus.

Advantages and Disadvantages

Advantages: - High-speed operation - CMOS technology for low power consumption - 3-state outputs for bus sharing - Wide operating voltage range

Disadvantages: - Limited output current capacity - Propagation delay may affect timing-sensitive applications

Working Principles

The CD74HCT573M operates based on the principles of digital logic. When the Latch Enable (LE) pin is high, the latch is enabled, and the data inputs are latched and transferred to the outputs. The Output Enable (OE) pin controls the state of the outputs. When OE is low, the outputs are enabled and reflect the stored data. When OE is high, the outputs are in a high-impedance state, allowing other devices to drive the bus.

Detailed Application Field Plans

The CD74HCT573M is commonly used in various digital systems and applications, including:

  1. Microcontrollers and microprocessors
  2. Data storage and retrieval systems
