54LS74A/BCAJC

This device contains two independent positive-edge-triggered D flip-flops with complementary outputs. The information on the D input is accepted by the flip-flops on the positive going edge of the clock pulse. The triggering occurs at a voltage level and is not directly related to the transition time of the rising edge of the clock. The data on the D input may be changed while the clock is low or high without affecting the outputs as long as the data setup and hold times are not violated. A low logic level on the preset or clear inputs will set or reset the outputs regardless of the logic levels.

Key specifications include an operating voltage range of 4.5V to 5.5V, a maximum supply current of 8mA, and a propagation delay of 35ns. The flip-flop operates at a frequency of up to 20MHz and is designed for use in a DIP package.

This component is suitable for digital logic applications requiring reliable data storage and transfer. Its dual flip-flop configuration allows for independent operation, making it versatile for various circuit designs.
