产品描述

This 10-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.

The ten latches are transparent D-type latches. 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. When OERB\ is taken low, the data present at the output of the data latches passes back onto the input data bus. When OERB\ is taken high, the output of the data latches is isolated from the D inputs. OERB\ does not affect the internal operation of the latches; however, precautions should be taken to avoid a bus conflict.

The SN74ALS994 is characterized for operation from 0°C to 70°C.
