asynchronously) when Latch Enable is high. When Latch Enable goes
low, data meeting the setup and hold times becomes latched.
when Output Enable is high, all device outputs are forced to the
high–impedance state. Thus, data may be latched even when the
outputs are not enabled.
Data Inputs on the opposite side of the package from the outputs to
facilitate PC board layout.
