74HC5958-BIT SHIFT REGISTER WITH 8-BIT OUTPUT REGISTERDescriptionPin AssignmentsThe 74HC595 is an high speed CMOS device.( Top View )An eight bit shift register accpets data from the serial input (DS) oneach positive transition of the shift register clock (SHCP). Whenasserted low the reset function () sets all shift register values tozero and is indepent of all clocks.Data from the input serial shift register is placed in the output registerwith a rising pulse on the storages resister clock (STCP). With theoutput enable ( E asserted low the 3-state outputs Q0-Q7 becomeactive and present thAll registers capture data on rising edge and change output on thefalling edge. If both clocks are connected together the input shiftregister is always one clock cycle ahead of the output 11SHCPQ7710MR89GNDSO-16 / TSSOP-16FeaturesApplications Wide Supply Voltage Range from 2.0V to 6.0V Sinks or Sources 8mA at VCC 4.5V CMOS Low Power Consumption Schmitt Trigger Action at All Inputs Inputs Accept up to 6.0V ESD Protection Tested per JESD 22 Exceeds 200-V Machine Model (A115-A) Exceeds 2000-V Human Body Model (A114-A) Exceeds 1000-V Charged Device Model (C101C) Latch-Up Exceeds 250mA per JESD 78, Class II Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3)Notes:Q7SGeneral Purpose LogicSerial to Parallel Data ConversionCapture and Hold Data for Extended Periods of TimeAllow Simple Serial Bit Streams from a Microcontroller to Controlas Many Peripheral Lines as NeededWide Array of Products such as: Computer Peripherals Appliances Industrial Control1.
