The
KK
74HCT573A is identical in pinout to the LS/ALS573. This
device may be used as a level converter for interfacing TTL or NMOS
outputs to High-Speed CMOS inputs.
These latches appear transparent to data (i.e., the outputs change
asynchronously) when Latch Enable is high. 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.
