带三态控制的8位上升沿触发D型触发器

The AiP74HC/HCT574 is an octal positive-edge triggered D-type flip-flop with 3-state outputs. The device features a clock (CP) and output enable (OE(—)) inputs. 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 • Input levels:\n• For AiP74HC574: CMOS level\n• For AiP74HCT574: TTL level\n• 3-state non-inverting outputs for bus oriented applications\n• 8-bit positive, edge-triggered register\n• Specified from -40℃ to +125℃\n• Packaging information: DIP20/SOP20/TSSOP20;

Octal D-type flip-flop; positive edge-trigger; 3-state
