HEF4508B Description
The HEF4508B is a dual 4-bit latch, which consists of two identical independent 4-bit latches with separate strobe (ST), master reset (MR), output-enable input (EO) and 3-state outputs (O). With the ST input in the HIGH state, the data on the D inputs appear at the corresponding outputs provided EO is LOW. Changing the ST input to the LOW state locks the HEF4508B MSI data into the latch.
