74HC595D,112 Datasheet PDF - Nexperia

The 74HC595D,112 is a 8-bit Serial-in, Serial or Parallel-out Shift Register with output latches, 3-state. The 74HC595 is high-speed Si-gate CMOS device and is pin compatible with low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard No. 7A. The 74HC595 is 8-stage serial shift register with a storage register and 3-state outputs. The register has separate clocks. Data is shifted on the positive-going transitions of the shift register clock input (SHCP). The data in each register is transferred to the storage register on a positive-going transition of the storage register clock input (STCP). If both clocks are connected together, the shift register will always be one clock pulse ahead of the storage register. The shift register has a serial input (DS) and a serial standard output (Q7S) for cascading. It is also provided with asynchronous reset (active LOW) for all 8 shift register stages.
