74HC574N Octal D-Type Flip Flop (Arduino/PIC) 20Pin DIP x 5Pcs
These octal edge-triggered D-type flip-flops 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 enter data on the low-to-high
transition of the clock (CLK) input.
A buffered output-enable (OE) input can be usedto place the eight outputs in either a normal logic state (high or low logic levels) or thehigh-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 without interface or pullup components.
