Additional Details

The TC74VCX244FT is characterized for operation from -40°C to +85°C, making it suitable for both commercial and industrial environments. The device includes power-down protection, which prevents current backflow when the device is powered off. 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, effectively disconnecting the device from the bus. This octal buffer/line driver is ideal for applications requiring high-speed and reliable signal transmission and buffering with controlled bus interfacing, ensuring efficient data handling in various digital systems.
