描述 Description

The ’HC75 and ’HCT75 are dual 2-bit bistable transparent

latches. Each one of the 2-bit latches is controlled by

separate Enable inputs (1E and 2E) which are active LOW.

When the Enable input is HIGH data enters the latch and

appears at the Q output. When the Enable input (1E and 2E)

is LOW the output is not affected.
