Product Summary

The 74HC595N is a 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 74HC595N is an 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 74HC595N 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 74HC595N 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. The storage register 74HC595N has 8 parallel 3-state bus driver outputs. Data in the storage register appears at the output whenever the output enable input (OE) is LOW.
