Description

    These octal edge-triggered D-type flip-flops of SN54HC574 feature 3-state outputs designed specifically for bus driving. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

    The eight flip-flops of SN54HC574 enter data on the low-to-high transition of the clock (CLK) input.

    A buffered output-enable (OE) input of SN54HC574 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 of SN54HC574 neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without interface or pullup components.
