Working Principles

The 74HCT4094DB,112 is a serial-in, parallel-out shift register with storage capability. It receives data serially through the SER pin and shifts it into its internal register upon receiving a clock signal at the SRCLK pin. The RCLK pin is used to latch the parallel outputs (Q0-Q7) from the internal register. The OE pin enables or disables the output stage, allowing control over when the parallel outputs are active.
