  • Non-inverting outputs for direct interface with microcontrollers and other digital logic devices
  • Output enable input allows the outputs to be disabled, putting them in a high-impedance state
  • Schmitt-trigger inputs provide improved noise immunity

Advantages and Disadvantages

Advantages: - High-speed operation - Low power consumption - Wide operating voltage range - Noise immunity due to Schmitt-trigger inputs - 3-state outputs for bus-oriented applications

Disadvantages: - Limited output current capacity - Not suitable for high-voltage applications

Working Principles

The SN74LVC373APWR operates as an octal transparent latch. When the output enable (OE) input is low, the latch is transparent, allowing the data inputs to pass through to the outputs. When OE is high, the latch holds the last data input values and the outputs are in a high-impedance state.

Detailed Application Field Plans

The SN74LVC373APWR is widely used in various digital systems, including but not limited to: - Microcontroller-based systems - Data storage and transfer systems - Address and data buses in computer systems - Communication systems - Industrial control systems
