SN74LS74AD Description

Short technical summary and product information.

The SN74LS74AD is a dual D-type flip-flop IC manufactured by Texas Instruments. Each flip-flop features independent set (preset) and reset functions, with data transferred on the positive-going edge of the clock pulse. This device operates with a supply voltage range of 4.75V to 5.25V and supports a maximum clock frequency of 35 MHz.

 

Designed for surface mounting, the SN74LS74AD comes in a 14-SOIC package with dimensions of 0.154 inches (3.90mm) in width. It is characterized for operation within an ambient temperature range of 0°C to 70°C. The output type is complementary, and it has a maximum propagation delay of 40ns at 5V and 15pF. This component is suitable for various digital logic applications requiring reliable flip-flop functionality.

 

Key electrical characteristics include a maximum IOL of 8 mA and a maximum IOH of -0.4 mA. The maximum supply current is 8000 µA. The device contains two independent flip-flop elements, each handling one bit of data. Its high-speed capability, indicated by a propagation delay of 10-50ns, makes it suitable for time-sensitive digital circuits.
