The parallel output will yield a signal that is inverted with respect to When data is applied to the serial data input (S-IN) and a clock the serial data input. pulse is applied to clock input (T), an “L” to “H” change of the clock Setting the LATCH input to “L” will prevent data from entering the will cause the data input signals to enter the internal shift registers latch. and the data in the shift registers will be shifted in order. When the EN input is set to “H”, all outputs (O1 – O8) will be set to OFF. Since the internal logic state of the IC is uncertain at poweron time, set the EN input to “H” (and outputs O1 – O8 will set to Parallel outputs BLOCK DIAGRAM Power supply VCC 4 Enable input EN 7 O1 O2 O3 O4 O5 O6 O7 O8 16 15 14 13 12 11 10 9 8 P-GND Driver GND Q Q Q Q Q Q Q Q L D L D L D L D L D L D L D L D D Q D Q D Q D Q D Q D Q D Q D Q Latch input LATCH 6 Serial input S-IN 2 T Clock T 1 3 L-GND Logic GND T T T T T T T 5 S-OUT Serial output MITSUBISHI <CONTROL / DRIVER IC> M54975P/FP Bi-CMOS 8-BIT SERIAL-INPUT LATCHED DRIVER OFF) until the input data is set and the internal logic state has been is the ground for the output driver section (O1 – O8), which is determined. made up of bipolar transistors that are capable of driving large L-GND is the ground of the CMOS logic circuit section and P-GND currents.
