Working Principles

The SN74AHC595NSRE4 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 transferred to the output latches on the rising edge of the RCLK input. The stored data can be accessed simultaneously from the eight output pins (QA to QH).
