Functional Features

The SN74LVC374APWT is a D-Type Transparent Latch with 8 flip-flops. It operates at low voltage and utilizes CMOS technology. The latch allows data to be stored and transferred based on the clock input. The output enable pin controls the output state, while the master reset pin resets all flip-flops to a known state.

Advantages and Disadvantages

Advantages: - Low voltage operation - High-speed performance - Compact package size - Easy integration into various circuits

Disadvantages: - Limited number of flip-flops - Not suitable for high-power applications

Working Principles

The SN74LVC374APWT works by latching the input data when the clock signal transitions from low to high. The latched data is then available at the output pins. The output enable pin can be used to disable the outputs, allowing for easy control of the data flow. The master reset pin resets all flip-flops to a low state when activated.

Detailed Application Field Plans

The SN74LVC374APWT is commonly used in various digital systems and applications, including:

  1. Microcontrollers
