Характеристики
74HC574D.653, 8-и разрядный триггер D-типа со срабатыванием …The 74HC574D is a 8-bit positive-edge triggered D-type Flip-flop with 3-state outputs. The device features a clock and 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 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.
