DESCRIPTION
The 74ABT845 consists of eight D-type latches with 3-State outputs. In addition to the LE, OE, MR and PRE pins, the 74ABT845 has two additional OE pins, making a total of three Output Enable (OE0, OE1, OE2) pins. The multiple Output enables allow multiuser control of the interface, e.g., CS, DMA, and RD/WR.
