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.
