POWER DOWN FUNCTION
In order to reduce the power consumption, in case of cascade connection, S6B2104 has a "power down
function".
.
- EOB and EIB pins works as input terminals.
- EOB and EIB pins work as output terminals. These terminals are set to the "H" level immediately after ENABLE F/F is
- The operation of ENABLE F/F is terminated and held unchanged until the next load pulse is detected. (For cascade
ENABLE F/F stops display data at "H" level input. ENABLE F/F starts display data at "L" level input.
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.
