• Compact Footprint: SOP package saves board space.

Additional Details:

The 74VHCT74AMXSOP39 consists of two independent D-type flip-flops with individual data, clock, set, and reset inputs. Information at the D input is transferred to the Q output on the positive-going edge of the clock pulse. The preset and clear inputs are active-low asynchronous inputs that override the clock and data inputs, allowing the flip-flops to be set or reset independently. The device is designed to interface directly with HC, HCT, and TTL logic families. Operating temperature range is -40°C to +85°C. The outputs are capable of driving 15 LSTTL loads.
