Functional Features

  • Octal transparent D-type latches with 3-state outputs
  • Latches store data when the latch enable (LE) input is high
  • Outputs are in a high-impedance state when the output enable (OE) input is low
  • Schmitt-trigger inputs provide noise immunity and allow slow input transition and better signal integrity

Advantages and Disadvantages

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

Disadvantages: - Limited output current capacity - Sensitive to electrostatic discharge (ESD) - Requires careful handling during assembly and usage

Working Principles

The SN74LVC373ADBRE4 operates as an octal transparent latch. When the latch enable (LE) input is high, the data inputs (D0-D7) are stored in the internal flip-flops. The stored data can be accessed through the corresponding data outputs (Q0-Q7). The output enable (OE) input controls the state of the outputs. When OE is low, the outputs are in a high-impedance state, allowing multiple devices to share a common bus.

Detailed Application Field Plans

The SN74LVC373ADBRE4 is commonly used in various electronic systems, including but not limited to: - Microprocessors and microcontrollers - Data storage systems - Communication devices - Industrial automation equipment - Automotive electronics
