3. - EOB and EIB pins works as input terminals.
ENABLE F/F stops display data at "H" level input. ENABLE F/F starts display data at "L" level input.
- EOB and EIB pins work as output terminals. These terminals are set to the "H" level immediately after ENABLE F/F is
initialized by the load pulse. Upon completion of 80-bit serial/parallel conversion using the shift clock input from the
CL2 terminal, these terminals are then set to the "L" level.
- The operation of ENABLE F/F is terminated and held unchanged until the next load pulse is detected. (For cascade
connection, refer to the application circuit drawing)
POWER DOWN FUNCTION
In order to reduce the power consumption, in case of cascade connection, S6B2104 has a "power down
function".
