  • The latch clock input transfers the data from the shift register to the output latches.
  • Output enable input allows for disabling the outputs.
  • Master reset input resets the shift register and output latches to their initial state.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows for compatibility with various systems. - High clock frequency enables fast data transfer. - Low power consumption due to LV logic family.

Disadvantages: - Limited number of stages (8) may not be sufficient for certain applications. - SSOP package may require specialized equipment for soldering.

Working Principles

The 74LV4094DB,118 is a serial-in, parallel-out shift register with output latches. It operates by shifting data into the shift register on each rising edge of the shift clock. The data is then transferred to the output latches upon receiving a pulse on the latch clock input. The outputs can be enabled or disabled using the output enable input. The master reset input resets the shift register and output latches to their initial state.

Detailed Application Field Plans

The 74LV4094DB,118 can be used in various applications, including: 1. Data storage and transfer in microcontrollers and microprocessors. 2. Serial-to-parallel data conversion in communication systems. 3. LED matrix control in display panels. 4. Address decoding in memory systems. 5. Control signal generation in industrial automation.
