Functional Description
The employment of silicon gate CMOS process of the M66313FP guarantees low power dissipation and maintains high
noise margin as well as high output current and high speed required to drive LEDs.
Each shift register bit consists of a flip-flop for shifting and an output latch.
The shift operation takes place when the clock input CK changes from low-level to high-level.
The serial data input A corresponds to the data input of the first-stage shift register, and the shift register is shifted in
sequence when a pulse is applied to CK.
The parallel outputs Q1 to Q32 are open-drain outputs.
If the latch-enable input LE is turned high–level, the content of the shift register at that instant is latched.
To expand the number of bits, use the serial data output SQ32 which shows the output of the shift register of the 32nd bit.
If the direct set input SD is turned low-level, shift register and latches are set.
If the high-level input is applied to the output enable input OE, Q1 to Q32 are set to the high-impedance state, but SQ32 is
not set to the high-impedance state. The shift operation is not affected when OE is changed.
