Additional Details

The HD74LV2G74AUSE-E comes in a US8 package. The propagation delay is typically in the nanosecond range. It operates over a temperature range of -40°C to +85°C. Each flip-flop has independent data (D), clock (CLK), clear (CLR), and preset (PR) inputs. The CLR and PR inputs are asynchronous, meaning they operate independently of the clock signal. The device is often used in applications requiring reliable data storage and high-speed operation. The inputs are also ESD protected.
