Features
Description
• True and Complementary Outputs
• Buffered Inputs and Outputs
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.
