onsemi MC74AC373DWR2G

The MC74AC373/74ACT373 consists of eight latches with 3−state outputs for bus organized system applications. The flip−flops appear transparent to the data when Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup time is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH, the bus output is in the high impedance state. The MC74AC373/74ACT373 contains eight D−type latches with 3−state standard outputs. When the Latch Enable (LE) input is HIGH, data on the Dₙ inputs enters the latches. In this condition the latches are transparent, i.e., a latch output will change state each time its D input changes. When LE is LOW, the latches store the information that was present on the D inputs a setup time preceding the HIGH−to−LOW transition of LE. The 3 - state standard outputs are controlled by the Output Enable (OE(overline)) input. When OE(overline) is LOW, the standard outputs are in the 2−state mode. When OE(overline) is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the latches.
