Working Principles

The 74LV4094D,118 is a serial-in, parallel-out shift register with output latches. It operates by shifting data bits into the register through the SER pin using the SRCLK input. The RCLK input latches the data into the parallel outputs (QH) when required. The OE pin enables or disables the outputs, allowing for tri-state operation.

Detailed Application Field Plans

  • Data storage and transfer in microcontrollers and digital systems
  • Serial-to-parallel conversion in communication protocols
  • LED matrix control in display applications
  • Address generation in memory devices

Detailed and Complete Alternative Models

  • 74HC4094: Similar shift register with higher voltage tolerance (up to 6V)
  • CD4094: Shift register with similar functionality but different logic family (CMOS)
