Логическая ИС SN74AUC1G74DCUR

Триггер , 74AUC1G74, D, 1.8 нс, 275 МГц, 9 мА, US8

The SN74AUC1G74DCUR is a single positive-edge-triggered D-type Flip-flop with clear and preset. A low level at the preset (PRE\) or clear (CLR\) input sets or resets the outputs, regardless of the levels of the other inputs. When PRE\ and CLR\ are inactive (high), data at the data (D) input meeting the setup time requirements is transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not related directly to the rise time of the clock pulse. Following the hold-time interval, data at the D input can be changed without affecting the levels at the outputs. To better optimize the flip-flop for higher frequencies, the CLR\ input overrides the PRE\ input when they are both low. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
