  • 3-state outputs: Enables bus-oriented applications by providing a high-impedance state when disabled.
  • Schmitt-trigger inputs: Enhances noise immunity by providing hysteresis.

Advantages and Disadvantages

Advantages

  • Low voltage operation: Can operate at low supply voltages, making it suitable for battery-powered devices.
  • High-speed operation: Provides fast data storage and output capabilities.
  • Noise immunity: Schmitt-trigger inputs ensure reliable operation in noisy environments.

Disadvantages

  • Limited output current: The maximum output current is ±24mA, which may not be sufficient for certain applications requiring higher current levels.
  • Temperature limitations: The operating temperature range of -40°C to +85°C may restrict its use in extreme temperature conditions.

Working Principles

SN74LV373ATPW operates as an octal transparent latch with 3-state outputs. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the corresponding outputs (Q0-Q7). The output enable (OE) input controls the output state, allowing the outputs to be either active or in a high-impedance state.

Detailed Application Field Plans

SN74LV373ATPW finds applications in various fields, including: 1. Microprocessor systems 2. Data storage systems 3. Communication equipment 4. Industrial automation 5. Automotive electronics
