this 8-bit flip-flop features 3-state outputs designed specifically for driving highly-capacitive or relatively low-impedance loads. it is particularly suitable for implementing buffer registers i/o ports bidirectional bus drivers and working registers. the eight flip-flops of the 74act11374 are edge-triggered d-type 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. an output-enable () input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a high-impedance state. in the high-impedance state the outputs neither load nor drive the bus lines significantly. view all in datasheet
