Additional Details
The PI74FCT244TQA operates from a 5V power supply and is specified for operation over the industrial temperature range. The device has two output enable (OE) inputs, each controlling four of the eight output buffers. When the OE input is low, the corresponding outputs are enabled; when the OE input is high, the outputs are in a high-impedance state. The non-inverting configuration ensures that the output signal matches the input signal in polarity and timing. The low ground bounce characteristic helps to minimize noise and signal distortion.
