Working Principles

The SN74HC590ADRE4 is a counter shift register that converts serial data into parallel format. It consists of eight flip-flops connected in series, forming an 8-bit shift register. The serial data input (DS) receives data bit by bit, which is then shifted through the flip-flops on each clock pulse (CP). The shifted data is stored in the storage register and can be accessed through the parallel outputs (QA to QH). The output enable (OE) pin controls the output state, and the master reset (MR) pin clears the register.
