Data is input to serial input S-IN, and clock pulses are input to clock input T. When the clock changes from low to high, the input Enable input 36 VCC registers is shifted sequentially. O12 2 35 O13 The serial output S-OUT is used to connect multiple M54992 to O11 3 34 O14 O10 4 33 O15 O9 5 32 O16 O8 6 31 O17 7 30 O18 8 29 expand the number of parallel outputs. S-OUT is connected to S-IN of the next stage. Parallel outputs For parallel output. When the clock pulse changes from low to high, latch input (LATCH) is high and output enable input (EN) is EN O7 low the serial input data at S-IN appears at output O1 and the other data already present is shifted sequentially to outputs O2 through GND O24. 9 10 The parallel outputs are inverted. M54992FP 1 data enters the first shift register and data already in the shift 28 GND 27 When the latch input is held low, the latch retains the stored data. O6 11 When the EN input is high, outputs O 1 through O24 all turn off. As O5 12 25 O20 26 O19 O4 13 24 O21 input should be kept high (setting outputs O1 through O24 off) until O3 14 23 O22 input data is set and the internal logic is initialized. O2 15 22 O23 L-GND is the GND of CMOS logic circuit and P-GND is the GND of O1 16 21 O24 Serial input S-IN 17 20 SO Clock T 18 the internal logic is unstable when the power is turned on, the EN output driver circuits O1 through O24 which employ bipolar transistors capable of large drive currents. Parallel outputs Parallel outputs Parallel outputs Serial input 19 LATCH Latch input An output load prevention circuit is built in this IC to prevent misoperation at power ON/OFF. Therefore, when VCC falls short of the fixed level, all outputs (O1 – O24) are compulsorily set to the OFF state.
