Please be aware that an important notice concerningavailability, standard warranty, and use in critical applications ofTexasInstruments semiconductor products and disclaimers theretoappears at the end of this data sheet.
These devices are positive-edge-triggered D-type flip-flops with acommon enable input. The 'HCT273 are similar to the 'HCT377, butfeature a common clear enable (
) input instead of a latched clock.
Information at the data (D) inputs meeting the setup timerequirements is transferred to the Q outputs on the positive-goingedge of the clock (CLK) pulse. Clock triggering occurs at aparticular voltage level and is not directly related to thepositive-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 toprevent false clocking by transitions at
The SN54HCT273 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. TheSN74HCT273 is characterized for operation from -40°C to85°C.
