__ __ A1 |1 \__/ 20| VCC B1 |2 19| OE# A2 |3 18| I/O1B B2 |4 17| I/O2B A3 |5 16| I/O3B B3 |6 15| I/O4B A4 |7 14| I/O5B B4 |8 13| I/O6B GND |9 12| I/O7B OE# |10 11| I/O8B ----------

Functional Features

  • Bidirectional voltage level translation: Allows data transfer between devices operating at different voltage levels.
  • Automatic direction control: Determines the direction of data flow based on the voltage levels of the A and B ports.
  • Output enable control: Enables or disables the outputs, providing flexibility in controlling data flow.

Advantages and Disadvantages

Advantages: - High-speed operation: Supports a maximum operating frequency of 400 MHz. - Low power consumption: Operates at low supply voltages, reducing power consumption. - Bidirectional communication: Facilitates data transfer in both directions.

Disadvantages: - Limited voltage range: Supports voltage translation between 1.2V and 3.6V only. - Package size: The SOIC package may not be suitable for space-constrained applications.

Working Principles

The 74LVT245BD,112 is a bidirectional level shifter/transceiver that allows data transfer between devices operating at different voltage levels. It utilizes automatic direction control to determine the direction of data flow based on the voltage levels of the A and B ports. When the OE# (Output Enable) pin is low, the outputs are enabled, and data can flow in either direction. Conversely, when the OE# pin is high, the outputs are disabled, preventing any data transfer.

Detailed Application Field Plans

The 74LVT245BD,112 is commonly used in various applications where voltage level translation is required. Some typical application fields include: - Communication systems - Data acquisition systems - Industrial automation - Consumer electronics - Embedded systems
