Working Principles

The 74HC595PW,118 is a serial-in, parallel-out shift register with output latches. It receives data serially through the SER pin and shifts it into the shift register on each rising edge of the SRCLK input. The data is then latched to the parallel outputs (QA-QH) on the rising edge of the RCLK input. The QH' pin provides a serial output for cascading multiple devices.
