74HCT574

The 74HC574; 74HCT574 is an 8-bit positive-edge triggered D-type flip-flop with 3-state outputs. The device features a clock (CP) and output enable (OE) inputs. The flip-flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Z80 Arduino Using Mega as Debugger

“Ever since the 80’s I’ve wanted to build a Z80 computer. I even bought the chips, but never used them. The reasons for this are varied. I never liked erasing and reprogramming EPROMs. My EPROM eraser died. I …
