onsemi MC74HCT573ADWGOS, Voltage Level Translator 1, 20-Pin SOIC

High-Performance Silicon-Gate CMOS
The MC74HCT573A is identical in pinout to the LS573. 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 times 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.
The HCT573A is identical in function to the HCT373A but has the Data Inputs on the opposite side of the package from the outputs to facilitate PC board layout.
