The M74HC595 is an high speed CMOS 8-BIT SHIFT REGISTERS/OUTPUT LATCHES (3-STATE)
The M74HC595 is a high-speed CMOS 8-bit shift register with output latches (3-state) fabricated with silicon gate C2MOS technology. It contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register with 3-state outputs. The device supports cascading via serial output pins and features separate clocks for the shift and storage registers.
