description

These octal D-type flip-flops are designed for

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.
