FUNCTIONAL DESCRIPTION
As R8A66161 uses silicon gate CMOS process. It realizes high-speed and high-output currents sufficient for
LED drive while maintaining low power consumption and allowance for high noises.
Each bit of a shift register consists of two flip-flop having independent clocks for shifting and latching.
As for clock input, shift clock input CKS and latch clock input CKL are independent from each other, shift and
latch operations being made when “L” changes to “H”.
Serial data input A is the data input of the first-step shift register and the signal of A shifts shifting registers
one by one when a pulse is impressed to CKS. When A is “H”, the signal of “L” shifts.
When the pulse is impressed to CKL, the contents of the shifting register at that time are stored in a latching
register, and they appear in the parallel data outputs from QA ~ QP.
Outputs QA ~ QP are open drain outputs.
To extend the number of bits, use the serial data output SQP which shows the output of the shifting register
of the 16th bit.
When reset input R is changed to “L”, QA ~ QP and SQP are reset. In this case, shifting and latching register
are set.
If “H” is impressed to output enable input OE, QA ~ QP reaches the high impedance state, but SQP does not
reach the high impedance state. Furthermore, change in OE does not affect shift operation.
