![]() SHIFT/LOAD Pin 15 Pin 15 is an enable pin of the IC, after activating the enable pin the parallel 8-bit parallel and serial input will be a shift with according to each clock pulse. ![]() H Pin 14 Pin 14 is used by the LSB of the 8-bit parallel data. F Pin 11 G Pin 12 SERIAL OUT Pin 13 Pin 13 is a serial output pin used to receive the converted 8 bit parallel data in a serial form. E Pin 10 After Pin 2 to 5, Pin 10 to 12 are used to give the remaining 3 -bits of the 8-bit parallel data as an input. CLEAR Pin 9 Pin 9 is a clear pin used to reset the output data and all internally stored data. GND Pin 8 Pin 8 is a ground pin used as common ground by IC with power supply, receiver and sender device. CLOCK Pin 7 Pin 7 is a clock pulse input pin used to change the state of the IC with respect to time. B Pin 3 C Pin 4 D Pin 5 CLOCK INHIBIT Pin 6 Pin 6 is a clock inhibit pin it is used to control the clock pulse signal. A Pin 2 Pin 2 to Pin 5 are the input pins, which are used to input the first 4 bits of 8-bits parallel data. PINS DETAIL SERIAL IN Pin 1 Pin 1 is a serial input pin used to input the serial data to the IC.
