High–Performance Silicon–Gate CMOS
The MC54/74HC533A is identical in pinout to the LS533. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
These latches appear transparent to data (i.e., the outputs change
asynchronously) when Latch Enable is high. The Data appears at the
outputs in inverted form. When Latch Enable goes low, data meeting the
setup and hold time becomes latched.
The Output Enable input does not affect the state of the latches, but 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.
The HC533A is identical in function to the HC563 but has the data inputs
on the opposite side of the package from the outputs to facilitate PC board
layout.
This device is similar in function to the HC373A, which has noninverting
outputs.
