Description

The SN74LVC2G74DCUR is a dual positive-edge-triggered D-type flip-flop with clear and preset features. It belongs to the Texas Instruments LVC family, designed for low-voltage operation and high-speed performance. This device operates with supply voltage levels ranging from 1.65 V to 5.5 V, making it suitable for a variety of digital applications.
Each flip-flop in the SN74LVC2G74DCUR has independent data, clock, preset (asynchronous set), and clear (asynchronous reset) inputs, along with complementary Q and Q-bar outputs. The device changes state on the rising edge of the clock pulse, storing the data present at the input D.
The clear function resets the output to low, while the preset function sets the output to high, regardless of the clock or data input states, offering flexibility in circuit design. It is packaged in small-outline (SOT) form factors, ideal for space-constrained applications. With features like 5.5 V tolerant inputs, low power consumption, and fast switching capabilities, the SN74LVC2G74DCUR is widely used in memory storage circuits, data registers, and digital data processing systems.
