74LVC273A OCTAL D-TYPE FLIP-FLOP WITH CLEAR Description Pin Assignments The 74LVC273A provides eight positive-edge-triggered D-type flip- flops with a direct clear (CLR) input. The device is designed for operation with a power supply range of 1.65V to 3.6V. The device is fully specified for partial power down applications using I . The I circuitry disables the output preventing OFF OFF damaging current backflow when the device is powered down. Features Supply Voltage Range from 1.65V to 3.6V Sinks or Sources 24mA at V = 3V CC CMOS Low Power Consumption I Supports Partial Power Down Operation OFF Inputs or Outputs accept up to 5.5V Inputs Can Be Driven by 3.3V or 5V Allowing for Mixed Voltage Applications Schmitt Trigger Action at All Inputs Typical V (Quiet Output Ground Bounce) less than 0.8V with OLP Applications V = 3.3V and T = +25C CC A Typical V (Quiet Output dynamic VOH) greater than 2.0V with OHV General Purpose Logic V = 3.3V and T = +25C CC A Bus Driving ESD Protection Tested per JESD 22 Power Down Signal Isolation Exceeds 200-V Machine Model (A115-A) Wide array of products such as: Exceeds 2000-V Human Body Model (A114-A) PCs, Notebooks, Netbooks, Ultrabooks Exceeds 1000-V Charged Device Model (C101C) Networking Computer Peripherals, Hard Drives, CD/DVD Latch-Up Exceeds 250mA per JESD 78, Class II ROM All devices are: TV, DVD, DVR, Set Top Box Totally Lead-Free & Fully RoHS compliant (Notes 1 & 2) Halogen and Antimony Free. Green Device (Note 3) Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 2.
