M66310P/FP
Functional Description
As M66310P/FP 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-flops 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 “L”, 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 outputs from QA to QP.
Outputs from QA to 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.
If CKS and CKL are connected, the state of the shifting register with one clock delay is outputted to QA to QP.
When reset input R is changed to “L”, QA to QP and SQP are reset. In this case, shifting and latching registers are reset.
If “H” is impressed to output enable input OE, QA to QP reaches the high impedance state, but SQP does not reach the
high impedance state. Furthermore, change in OE does not affect shift operation.
