Description

The CD74AC174 and ’ACT174arehex D flip-flops with reset
that utilize AdvancedCMOSLogictechnology. Information at
the D input is transferred to the Q output on the positive­going edge of the clock pulse. All six flip-flops are controlled
by a common clock (CP) and a common reset (

MR). Reset­ting is accomplished by a low voltage level independent of
the clock.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTES:

3. For up to 4 outputs per device, add ±25mA for each additional output.

4. Unless otherwise specified, all voltages are referenced to ground.

5. θJA is measured with the component mounted on an evaluation PC board in free air.
