description/ordering information

The ’ACT74 dual positive-edge-triggered devices are D-type flip-flops.
A low level at the preset (PRE) or clear (CLR) input sets or resets the outputs, regardless of the levels of the
other inputs. When PRE and CLR are inactive (high), data at the data (D) input meeting the setup-time
requirements is transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs
at a voltage level and is not directly related to the rise time of the clock pulse. Following the hold-time interval,
data at D can be changed without affecting the levels at the outputs.
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.
