TECHNICAL DATA
Octal 3-State Noninverting
Transparent Latch
High-Performance Silicon-Gate CMOS
KK74ACT573
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.
• TTL/NMOS Compatible Input Levels
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 µA; 0.1 µA @ 25°C
• Outputs Source/Sink 24 mA
