Additional Details

The PI74FCT244CTQX operates from a 5V supply voltage. It has two output enable (OE) inputs. When OE is low, the corresponding outputs are enabled, and the buffered signal is present. When OE is high, the outputs are in a high-impedance state, allowing other devices to drive the bus. The non-inverting characteristic of the outputs ensures that the output signal is the same polarity as the input signal. The device’s low ground bounce characteristic is crucial for maintaining signal integrity, especially in high-speed environments. It is commonly used in applications where high speed, low power, and high reliability are important factors. The specific timing characteristics, power dissipation, and package details can be found in the manufacturer's datasheet.
