The devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The eight flip-flops of the ’ACT374 devices are D-type edge-triggered flip-flops. On the positive transition of the clock (CLK) input, the Q outputs are set to the logic levels set up at the data (D) inputs. 1 20 2 19 3 18 4 17 5 16 6 15 7 14 8 13 9 12 10 11 VCC 8Q 8D 7D 7Q 6Q 6D 5D 5Q CLK 1D 1Q OE VCC SN54ACT374 . . . FK PACKAGE (TOP VIEW) 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 the increased drive provide the capability to drive bus lines in bus-organized systems without need for interface or pullup components. 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 CLK 5Q 5D 2D 2Q 3Q 3D 4D 8Q D D D D OE does not affect internal operations of the flip-flop. Old data can be retained or new data can be entered while the outputs are in the high-impedance state. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
