description/ordering information

These devices are positive-edge-triggered D-type flip-flops with a common enable input. The ’HCT273 devices
are similar to the ’HCT377 devices, but feature a common clear enable (CLR) input instead of a latched clock.
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 (CLK) pulse. Clock triggering occurs at a particular voltage level and is not
directly related to the positive-going pulse. When CLK is at either the high or low level, the D input has no effect
at the output. The circuits are designed to prevent false clocking by transitions at CLR.
ORDERING INFORMATION

†Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are
available at www.ti.com/sc/package.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
