  • Shift register function: Enables serial-to-parallel or parallel-to-serial data conversion.
  • 3-state outputs: Provides high impedance state when disabled, allowing multiple devices to share a common bus.

Advantages

  • High-speed operation allows for efficient data processing.
  • Low power consumption makes it suitable for battery-powered applications.
  • Wide operating voltage range provides flexibility in various electronic systems.
  • Schmitt-trigger inputs ensure reliable operation in noisy environments.

Disadvantages

  • Limited number of addressable latches (8-bit).
  • Not suitable for applications requiring higher clock frequencies.

Working Principles

The MC74VHCT259ADTR2G is designed as an 8-bit addressable latch/shift register. It can operate in two modes: latch mode and shift mode. In latch mode, the data inputs are latched and stored in the internal registers based on the clock and latch control signals. In shift mode, the data is shifted through the internal registers based on the clock signal. The output enable signal controls the output state of the device.

Detailed Application Field Plans

  • Data multiplexing/demultiplexing in digital systems.
  • Serial-to-parallel or parallel-to-serial data conversion.
  • Addressable memory storage and retrieval.
  • Control signal generation and distribution.

Detailed and Complete Alternative Models

  1. SN74HC595N: 8-bit serial-in, parallel-out shift register with output latches.
  2. CD4015BE: Dual 4-stage static shift register with serial input and parallel output.
  3. 74HC164N: 8-bit serial-in, parallel-out shift register with asynchronous reset.

Note: These alternative models offer similar functionality but may have different specifications and pin configurations.
