SL74HCT573
Octal 3-State Noninverting Transparent Latch
High-Performance Silicon-Gate CMOS
The SL74HCT573 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.
• 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
