DESCRIPTION

The M74HC574 is an high speed CMOS OCTAL D-TYPE FLIP FLOP WITH 3-STATE OUTPUTS INVERTING fabricated with sub-micron silicon gate C

MOS technology. This 8 bit D-TYPE FLIP FLOP is con trolled by a clock input (CK) and an o utpu t enable input (OE On the positive transition of the clock, the Q outputs will be set to the logic state that were setup at the D inputs. While the OE

input is at low level, the eight outputs

will be in a norm al logic state (high or low logic

while the outputs are off. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
