8-Bit Shift Register SC74HC595 ic

SC74HC595 utilizes advanced CMOS technology, and has 8-bit shift register with serial input, serial/parallel output and 8-bit tri-state output flip-latch. The pin configuration is in accord with the 54LS/74LS series, and the operating speed is similar to 54LS/74LS. This circuit has the protecting circuit for all the inputs and outputs to avoid the damage caused by the static discharge. And it has the ability of driving load and features high noise immunity. The register and flip-latch both have separate clock inputs (SCK and RCK). The serial input data (IS) is stored into register at the rising edge of SCK; the data of register is stored into flip-latch at the rising edge of RCK.The low level of clear port (SCLR) only reset the register, and is no effect to flip-latch. When the control enable (G) is high level, the parallel-out is level Z.
