!
The MC74LVX573 is an advanced high speed CMOS octal latch 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 latch is controlled by a latch enable input and an
output enable input. When the output enable input is high, the eight
outputs are in a high impedance state.
