  • Latch enable (LE) input allows data to be stored or transferred to the outputs
  • Output enable (OE) input enables/disables the outputs
  • Schmitt-trigger action on all inputs provides hysteresis for improved noise immunity

Advantages and Disadvantages

Advantages: - High-speed operation - Low power consumption - ESD protection for robustness - Schmitt-trigger action for noise immunity

Disadvantages: - Limited output current capacity - Restricted supply voltage range

Working Principles

The 74HCT573D-Q100,118 is an octal D-type transparent latch. It stores data when the latch enable (LE) input is high and transfers the stored data to the outputs when LE is low. The output enable (OE) input controls the state of the outputs. The Schmitt-trigger action on all inputs ensures reliable operation in the presence of noise.

Detailed Application Field Plans

The 74HCT573D-Q100,118 can be used in various applications, including: - Data storage and transfer in microcontrollers and microprocessors - Address decoding in memory systems - Bus interfacing in digital systems - General-purpose logic-level conversion
