8 Bit Serial to Parallel Converter Test Circuit - 74HC595

In this experiment, we will examine the 74HC595 IC. Many digital applications can be made with this integration that converts a serial data to parallel data in the binary number system. It is mostly used as SPI interface in Microcontroller systems.

In a digital system, the 74HC595 IC is one of the most used CMOS ICs when serial data needs to be converted and processed into parallel data.
The 74HC595 integrated has DIP production as well as SOIC-16, TSSOP-16 sheathed productions. Some other technical features are as follows:
2 volts-7 volts supply voltage,
TTL compatibility,
1 micro amp input current,
Operating frequency up to 35 MHz,
8 pcs D type Latch

74HC595 Timing Diagram:

The functions of the pins of the 74HC595 are as follows:
Shift Clock: When it drops from 1 to 0, the data starts to shift.
Latch Clock: The data-bit progressing in the shift register is transferred to the output.
Reset: When it drops from 1 to 0, the shift register is reset.
Output Enable: When 0, the floating bits are exported.
Serial Data Input: Input end of serial data.

We also used a signal generator in our application circuit. We have already assembled this generator, which also produces square waves. We observed the progress of the serial data by changing the frequency between 1Hz and 10Hz.
