TECHNICAL DATA
KK74ACT533
Octal 3-State Inverting
Transparent Latch
High-Speed Silicon-Gate CMOS
The KK74ACT533 is identical in pinout to the LS/ALS533,
HC/HCT533. The KK74ACT533 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. The data appears as 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.
