Additional Details

The TC74VCX2244FT operates over a temperature range of -40°C to +85°C, suitable for industrial and commercial applications. Power-down protection prevents backflow current when the device is powered off, enhancing system reliability. 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 octal buffer/line driver is ideal for applications that require high-speed signal transmission and buffering with controlled bus interfacing.
