Additional Details
The PI74FCT244TLC operates from a 5V power supply and is characterized for operation over the industrial temperature range. The device has two output enable (OE) pins, each controlling four of the eight output buffers. When the OE pin is low, the outputs are enabled; when high, the outputs are in a high-impedance state. The non-inverting configuration ensures that the output signal matches the input signal in polarity. The low ground bounce characteristic minimizes noise generation, contributing to improved signal integrity. The device's high-speed operation makes it suitable for demanding applications where data rates are critical. Further details regarding timing characteristics, power dissipation, and package dimensions can be found in the manufacturer's datasheet.
