74HCT595 8-BIT SHIFT REGISTER WITH 8-BIT OUTPUT REGISTER Description Pin Assignments The 74HCT595 is an high speed CMOS device that is designed to be pin compatable with 74LS low power Schottky types. An eight bit shift register accpets data from the serial input (DS) on each positive transition of the shift register clock (STCP). When asserted low the reset function (MR) sets all shift register Preliminary values to zero and is indepent of all clocks. Data from the input serial shift register is placed in the output register with a rising pulse on the storages resister clock (SHCP). With the output enable (OEሻ asserted low the 3-state outputs Q0Q7 become active and present th All registers capture data on rising edge and change output on the falling edge. If both clocks are connected together the input shift register is always one clock cycle ahead of the output register. Features Applications • Supply Voltage Range from 4.5V to 5.5V • General Purpose Logic • Sinks or sources 8mA at VCC = 4.5V • Serial to Parallel Data conversion • CMOS low power consumption • Capture and hold data for extended periods of time. • Schmitt Trigger Action at All Inputs • Allow simple serial bit streams from a microcontroller to • Inputs accept up to 6.0V • ESD Protection Tested per JESD 22 control as many peripheral lines as needed. • Exceeds 200-V Machine Model (A115-A) o Computer peripherals Exceeds 2000-V Human Body Model (A114-A) o Appliances Exceeds 1000-V Charged Device Model (C101C) o Industrial control • 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: Wide array of products such as: 1.
