Product Summary
The 74ABT573CPC is an octal latch with buffered common Latch Enable (LE) and buffered common Output Enable (OE) inputs. This device is functionally identical to the ABT373 but has broadside pinouts. The 74ABT573CPC contains eight D-type latches with 3-STATE output buffers. When the Latch Enable (LE) input is HIGH, data on the Dn inputs enters the latches. In this condition the latches of the 74ABT573CPC 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 buffers of the 74ABT573CPC are controlled by the Output Enable (OE) input. When OE is LOW, the buffers are in the bi-state mode. When OE is HIGH the buffers are in the high impedance mode but this does not interfere with entering new data into the latches.
