It has four address inputs (DA to DD), an active HIGH latch disable input (LD), an active HIGH blanking input (BI), an active HIGH phase input (PH) and seven buffered segment outputs (Oa to Og).
The circuit provides the function of a 4-bit storage latch and an 8-4-2-1 BCD to 7-segment decoder/driver.
It can invert the logic levels of the output combination.
The phase (PH), blanking (BI) and latch disable (LD) inputs are used to reverse the functio...
