Functional Features

• Octal transparent latch: The SN74LVC373APWE4 can store and control data on its eight input pins (D0-D7) using the latch enable (LE) pin.
• 3-state outputs: The device features 3-state outputs (Q0-Q7), allowing multiple devices to be connected to a common bus without interference.
• High-speed operation: The SN74LVC373APWE4 operates at high speeds, making it suitable for applications requiring fast data transfer.
• Low power consumption: It is designed to consume low power, making it energy-efficient.
• Schmitt-trigger inputs: The device incorporates Schmitt-trigger inputs, providing improved noise immunity.

Advantages and Disadvantages

Advantages

• High-speed operation enables efficient data transfer.
• Low power consumption helps conserve energy.
• Schmitt-trigger inputs enhance noise immunity, ensuring reliable performance in noisy environments.
• 3-state outputs allow for easy integration into bus-oriented systems.

Disadvantages

• Limited voltage range (1.65V to 5.5V) may restrict compatibility with certain systems.
• TSSOP package may require careful handling during assembly.

Working Principles

The SN74LVC373APWE4 operates as an octal transparent latch. When the latch enable (LE) input is high, the data on the eight input pins (D0-D7) is stored and reflected on the corresponding output pins (Q0-Q7). When the LE input is low, the outputs are in a high-impedance state, allowing other devices to drive the bus.
