The MC74LVX574 is an advanced high speed CMOS octal flip-flopwith 3-state outputs. The inputs tolerate voltages up to 7V allowing theinterface of 5V systems to 3V systems. This 8-bit D-type flip-flop is controlled by a clock pulse input and anoutput enable input. When the output enable input is high the eightoutputs are in a high impedance state.
