com 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 highimpedance state.
Thus...
