Working Principles
The 74HC299DB,112 is a serial-in, parallel-out shift register IC. It receives data serially through the SER pin and shifts it into its internal register upon each rising edge of the SRCLK input. The RCLK input latches the data from the internal register to the parallel outputs (QH). The OE pin controls the tri-state outputs, allowing them to be disabled when necessary. The QH' pin provides a serial output of the last shifted bit.
Detailed Application Field Plans

- Serial-to-parallel data conversion
- Digital communication protocols
- Microcontroller interfacing
- LED matrix control
