74LVC273A
NEW PRODUCT
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 I
OFF
. The I
OFF
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 V
CC
= 3V
• CMOS Low Power Consumption
• I
OFF
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 V

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.
