About this manual

The 74VHC574 is an advanced high-speed CMOS octal D-type flip-flop with 3-state non-inverting outputs. It is fabricated with sub-micron silicon gate and double-layer metal wiring CMOS technology. The device is controlled by a clock input (CK) and an output enable input (OE). On the positive transition of the clock, the Q outputs are set to the logic states that were setup at the D inputs. While the OE input is low, the 8 outputs are in a normal logic state; while high, the outputs are in a high impedance state. Power down protection is provided on all inputs, allowing 0 to 7V to be accepted on inputs with no regard to the supply voltage. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity.
