Additional Details

The TC74VHCT244AF operates from a supply voltage of 4.5V to 5.5V. It has a typical propagation delay of around 5 ns. The output enable (OE) pin controls the three-state outputs, allowing for bus isolation and multiplexing. The device is available in a surface-mount package, such as a SOIC or TSSOP. The operating temperature range typically spans from -40°C to +85°C. It's essential to review the datasheet for precise electrical characteristics, timing diagrams, and application recommendations to ensure proper functionality within the intended system.
