The 74LVC573A consists of eight D-type transparent latches, featuring separate D-type inputs for each latch and 3-state true outputs for bus-oriented applications. A Latch Enable (LE) input and an Output Enable (OE) input are common to all internal latches. When LE is HIGH, data at the Dn inputs enters the latches. In this condition, the latches are transparent, that is, a latch output will change each time its corresponding D-input changes.
