74HC595PW Datasheet

Logic - Shift Registers


The 74HC595 and 74HC595PW are high-speed Si-gate CMOS devicesand are pin compatible with low power Schottky TTL(LSTTL). They are specified in compliance with JEDECstandard no. 7A.The 74HC/HCT595 is an 8-stage serial shift register with astorage register and 3-state outputs. The shift register andstorage register have separate clocks.Data is shifted on the positive-going transitions of theSH_CP input. The data in each register is transferred tothe storage register on a positive-going transition of theST_CP input. If both clocks are connected together, theshift register will always be one clock pulse ahead of thestorage register.The shift register has a serial input (DS) and a serialstandard output (Q7’) for cascading. It is also providedwith asynchronous reset (active LOW) for all 8 shiftregister stages. The storage register has 8 parallel 3-statebus driver outputs. Data in the storage register appears atthe output whenever the output enable input (OE) is LOW. 74HC595PW Features • 8-bit serial input• 8-bit serial or parallel output• Storage register with 3-state outputs• Shift register with direct clear• 100 MHz (typical) shift out frequency• ESD protection:HBM EIA/JESD22-A114-A exceeds 2000 VMM EIA/JESD22-A115-A exceeds 200 V. 74HC595PW Applications • Serial-to-parallel data conversion• Remote control holding register
