SC74HC595 8-BIT SHIFT REGISTER (SERIAL INPUT, 3S PARALLEL OUTPUT WITH LATCHES) DESCRIPTION SC74HC595 utilizes advanced CMOS technology, and has 8-bit shift register with serial input, serial/parallel output and 8bit tri-state output flip-latch. The pin configuration is in accord SOP-16-300-1.27 SOP-16-225-1.27 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 SSOP-16-300-0.65 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 DIP-16-300-2.54 TSSOP-16-225-0.65 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 fliplatch. When the control enable ( G ) is high level, the parallel- ORDERING INFORMATION out is level Z.
