74LVC273A
OCTAL D-TYPE FLIP-FLOP WITH CLEAR
Description
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 IOFF. The IOFF circuitry disables the output preventing
damaging current backflow when the device is powered down.
Features
• Supply Voltage Range from 1.65V to 3.6V
• Sinks or Sources 24mA at VCC = 3V
• CMOS Low Power Consumption
• IOFF Supports Partial Power Down Operation
• 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 VOLP (Quiet Output Ground Bounce) less than 0.8V with
VCC = 3.3V and TA = +25°C
• Typical VOHV (Quiet Output dynamic VOH) greater than 2.0V with
VCC = 3.3V and TA = +25°C
• 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
• All devices are:
Totally Lead-Free & Fully RoHS compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
Pin Assignments
Applications
• General Purpose Logic
• Bus Driving
• Power Down Signal Isolation
• Wide array of products such as:
PCs, Notebooks, Netbooks, Ultrabooks
Networking Computer Peripherals, Hard Drives, CD/DVD
ROM
TV, DVD, DVR, Set Top Box
Notes:
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen and Antimony free,
"Green" and Lead-Free.
3. Halogen and Antimony free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and
<1000ppm antimony compounds.

Notes:
6. Stresses beyond the absolute maximum may result in immediate failure or reduced reliability. These are stress values and device operation should be
within recommend values.
7. Forcing the maximum allowed voltage could cause a condition exceeding the maximum current or conversely forcing the maximum current could
cause a condition exceeding the maximum voltage. The ratings of both current and voltage must be maintained within the controlled range.
