FK PACKAGE (TOP VIEW) 1D 1Q OE VCC The eight latches are D-type transparent latches. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the logic levels set up at the D inputs. 2D 2Q 3Q 3D 4D 4 3 2 1 20 19 18 5 17 6 16 7 15 8 14 9 10 11 12 13 8D 7D 7Q 6Q 6D 4Q GND LE 5Q 5D A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines in bus-organized systems without need for interface or pullup components. 8Q D D D D OE does not affect the internal operations of the latches. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.
