Description and Introduction
3.3V Octal buffer/line driver with 30Ohm series termination resistors (3-State) The 74LVT2244 is a 3.3V Octal Buffer/Line Driver with 3-State Outputs, manufactured by Fairchild Semiconductor. It is designed for low-voltage (3.3V) VCC operation but is 5V tolerant on the inputs and outputs. The device features eight non-inverting buffers with 3-state outputs, which are controlled by two output enable (OE) inputs. Each OE input controls four buffers. The 74LVT2244 is part of the LVT (Low Voltage Technology) family, which offers high-speed performance with low power consumption. It is available in various package options, including TSSOP and SSOP. The device is suitable for applications requiring high-speed bus interfacing and driving heavy loads.
