Functional Features

  • Serial-to-parallel conversion: The SN74HC165ANSR can convert serial data input into parallel output.
  • High-speed operation: It operates at a maximum clock frequency of 100 MHz, allowing for fast data transfer.
  • Cascadable: Multiple SN74HC165ANSR ICs can be cascaded to increase the number of parallel outputs.
  • Master reset: The MR pin allows for resetting the shift register to its initial state.
  • Shift/load control: The SH/LD pin controls the shift or load operation of the shift register.

Advantages and Disadvantages

Advantages: - High-speed operation enables quick data transfer. - Cascadable feature allows for expanding the number of parallel outputs. - Small package size (SOIC) makes it suitable for space-constrained applications.

Disadvantages: - Limited number of parallel outputs (8 bits). - Requires an external clock signal for operation.

Working Principles

The SN74HC165ANSR is a serial-in, parallel-out shift register. It receives serial data input through the SER pin and shifts the data into its internal storage registers on each rising edge of the clock signal applied to the CLK pin. The parallel output is available on the D0-D7 pins. The shift/load operation is controlled by the SH/LD pin. When SH/LD is low, the shift operation is enabled, allowing the data to be shifted in. When SH/LD is high, the load operation is enabled, latching the data from the serial input into the parallel output registers.

Detailed Application Field Plans

The SN74HC165ANSR can be used in various applications, including:

  1. Data acquisition systems
  2. Serial-to-parallel conversion in communication interfaces
  3. Industrial automation and control systems
  4. LED matrix displays
  5. Keypad scanning circuits
  6. Digital counters and timers
