NXP 74HC595 8-Bit Shift Register SOIC-16

The NXP 74HC595 8-Bit Shift Register is a high-speed Si-gate CMOS device that is pin compatible with low-power Schottky TTL (LSTTL). Specified in compliance with JEDEC standard No. 7A, this device functions as an 8-stage serial shift register equipped with a storage register and 3-state outputs.

The registers feature separate clocks for precise control. Data is shifted on the positive-going transitions of the shift register clock input (SHCP), while the data in each register transfers 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.

This shift register includes a serial input (DS) and a serial standard output (Q7S) for easy cascading. It is also provided with an asynchronous reset (active LOW) for all 8 shift register stages. The storage register features 8 parallel 3-state bus driver outputs, with data appearing at the output whenever the output enable input (OE) is LOW.

• 8-bit serial input and 8-bit serial or parallel output
