... Dot drivers of thermal printer heads, serial/parallel conversion. Drivers for relays and solenoids. FUNCTION The M54992 consists of 24 stages of D-type flip flops connected to 24 latches. 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 data enters the first shift register and data already in the shift registers is shifted sequentially ...
