This 8-bit latch is designed specifically for storing the contents of the input data bus and providing the capability of reading back the stored data onto the input data bus. While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. Read back is provided through the output-enable (OERB) input.
