The MC74LVX374 is an advanced high speed CMOS octal D–type
flip–flop with 3–state outputs. The inputs tolerate voltages up to 7V,
allowing the interface of 5V systems to 3V systems.
This 8–bit D–type flip–flop is controlled by a clock input and an output
enable input. When the output enable input is high, the eight outputs are
in a high impedance state.
