IN74LV574 Octal D-type flip-flop; positive edge-trigger (3-State)
The 74LV574 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT574. The 74LV574 is an octal D-type flip–flop featuring separate D-type inputs for each flip-flop and non-inverting 3-state outputs for oriented applications. A clock (CP) and an output enable (OE) input are common to all flip-flops. The eight flip-flops will store the state of their individual Dinputs that meet the set-up and hold times requirements on the LOW-toHIGH CP transition. When OE is LOW, the contents of the eight flip-flops are available at the outputs. When OE is HIGH, the outputs go to the high impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops.
