Functional Features

• Octal D-type transparent latches with 3-state outputs
• Latch enable and output enable inputs for control
• High-speed operation with a maximum frequency of 125 MHz
• Wide supply voltage range allows compatibility with various systems
• 3-state outputs provide flexibility in signal routing

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data processing - Wide supply voltage range enhances compatibility - 3-state outputs offer flexibility in signal routing

Disadvantages: - Limited number of latches (8) may not be sufficient for certain applications requiring more inputs/outputs - SSOP package may require specialized handling during assembly

Working Principles

The 74LV573DB,118 operates as an octal D-type transparent latch with 3-state outputs. It can store data at its inputs and hold it until the latch enable (LE) input is activated. When the LE input is high, the data at the inputs is transferred to the outputs. The output enable (OE) input controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The 74LV573DB,118 can be used in various applications that require logic level shifting and signal storage. Some potential application fields include: - Microcontroller interfacing - Data communication systems - Memory address decoding - Bus drivers
