Functional Features

The MC74HC165ADTR2 is a high-speed CMOS logic integrated circuit that serves as an 8-bit parallel-in/serial-out shift register. It allows for the conversion of serial data into parallel format. The device operates within a wide supply voltage range of 2.0V to 6.0V and can handle clock frequencies up to 80 MHz.

The shift register has a serial data input (SER) and a serial data output (QH, QH', QH''). It also features a parallel data output (QA-QG) that provides the converted parallel data. The shift/load input (SH/LD) controls the shifting and loading operations, while the clock input (CLK) synchronizes the data transfer.

Advantages and Disadvantages

Advantages: - High-speed operation - Wide supply voltage range - Compact TSSOP-16 package - Easy conversion from serial to parallel data

Disadvantages: - Limited number of bits (8) - Requires an external clock signal for proper functioning

Working Principles

The MC74HC165ADTR2 operates based on the principle of serial-to-parallel data conversion. When the shift/load input (SH/LD) is low, the device shifts the data present at the serial data input (SER) into its internal shift register on each rising edge of the clock input (CLK). The shifted data can be read from the parallel data outputs (QA-QG).

When the shift/load input is high, the device enters the parallel load mode. In this mode, the data present at the serial data input is loaded into the shift register on the next rising edge of the clock input. This allows for the parallel transfer of data.

Detailed Application Field Plans

The MC74HC165ADTR2 finds applications in various fields where serial-to-parallel data conversion is required. Some potential application areas include:

1. Data communication systems
2. Industrial automation
3. Robotics
4. Instrumentation
5. Automotive electronics
