description
These octal D-type flip-flops are designed for
2.7-V to 5.5-V V_CC operation.
The ’LV273 are positive-edge-triggered flip-flops
with direct clear (CLR) input. Information at
the data (D) inputs meeting the setup time
requirements is transferred to the Q outputs on the
positive-going edge of the clock pulse. Clock
triggering occurs at a particular voltage level and
is not directly related to the transition time of the
positive-going pulse. When the clock (CLK) input
is at either the high or low level, the D-input signal
has no effect at the output.

The SN74LV273 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count
and functionality of standard small-outline packages in less than half the printed-circuit-board area.
The SN54LV273 is characterized for operation over the full military temperature range of –55°C to 125°C. The
SN74LV273 is characterized for operation from –40°C to 85°C.
