Description

The KK74ACT373 is identical in pinout to the LS/ALS373, HC/HCT373. The KK74ACT373 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.
