TECHNICAL DATA
KK74ACT573
Octal 3-State Noninverting
Transparent Latch
High-Performance Silicon-Gate CMOS
The KK74ACT573 is identical in pinout to the LS/ALS573,
HC/HCT573. The KK74ACT573 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.
