The SNJ54AS74J is an integrated circuit (IC) component manufactured by Texas Instruments. As a dual D-type flip-flop, it is a versatile and widely used IC in digital electronics. Here is an overview of its key features:
1. D-type flip-flops: The SNJ54AS74J contains two individual D-type flip-flops with active-high inputs. Each flip-flop has a data (D) input, a clock (CLK) input, a preset (PR) input, and a clear (CLR) input.
2. Complementary outputs: It provides complementary outputs (Q and Q?) for each flip-flop, giving the user flexibility in signal routing and logic design.
3. Active-high clock: The IC operates with an active-high clock (CLK) input. When a positive edge is applied to this input, it transfers the logic level from the D input to the Q output.
4. Asynchronous preset (PR) and clear (CLR) inputs: The SNJ54AS74J offers an asynchronous preset (PR) input and an asynchronous clear (CLR) input for each flip-flop. The PR input sets the Q output to logic HIGH when asserted, overriding the D input. Similarly, the CLR input clears the Q output to logic LOW when activated, regardless of the D input.
5. Wide supply voltage range: It can operate within a wide supply voltage range of 4.5 V to 5
