Working Principles

The 74ALVCHR16269ALRG4 is a logic level translator IC designed to enable communication between devices operating at different voltage levels. It utilizes a combination of voltage level shifters and bidirectional buffers to ensure seamless data transfer.

The IC features separate power supply pins (VCCA and VCCB) for the input and output sides, allowing it to interface between voltage domains with different power supplies. The OEAB and OEBA pins control the direction of data flow, enabling bidirectional communication.

When an input signal is applied to one side of the IC, it undergoes level shifting to match the voltage requirements of the other side. The translated signal is then available at the corresponding output pin.

Detailed Application Field Plans

The 74ALVCHR16269ALRG4 is commonly used in various applications where logic level translation is required. Some of the typical application fields include:

  1. Microcontroller interfacing with different voltage peripherals
  2. Communication interfaces between devices operating at different voltage levels
  3. Battery-powered systems requiring efficient voltage level shifting
  4. Industrial automation and control systems
  5. Consumer electronics, such as smartphones and tablets
