Additional Details

The TC74VCX164245FT is characterized for operation from -40°C to +85°C, making it suitable for both commercial and industrial applications. The device includes power-down protection, which prevents current backflow when the device is powered off. The direction of data flow is controlled by the DIR input. When DIR is high, data flows from A to B, and when DIR is low, data flows from B to A. The output enable (OE) input controls the 3-state outputs. When OE is low, the outputs are enabled, and when OE is high, the outputs are in a high-impedance state. This device is an ideal solution for level translation applications requiring high-speed and reliable data communication.
