The 74HC109D-Q100J is an IC (Integrated Circuit) component featuring dual J-K flip-flops, manufactured by Nexperia. It is specifically designed for automotive applications and complies with the AEC-Q100 standard, ensuring high reliability in harsh automotive environments. Below are the key features and an overview of this component:
1. Dual Flip-Flops: The 74HC109D-Q100J consists of two independent J-K type flip-flops with individual clock (CP), preset (PR), and clear (CLR) inputs. This dual configuration makes it suitable for applications requiring multiple flip-flops.
2. High-Speed Operation: This IC operates at high speed, allowing for fast switching and data transfer. It can handle clock frequencies up to 99 MHz, which makes it suitable for various time-critical applications.
3. Schmitt Trigger Inputs: The inputs (CP, PR, CLR) are equipped with Schmitt triggers, which provide hysteresis, ensuring improved noise immunity in noisy environments.
4. Asynchronous Clear and Preset Inputs: The 74HC109D-Q100J offers asynchronous clear and preset inputs, which allow for immediate clearing or setting of the flip-flop outputs independent of the clock input. This feature enhances flexibility and ease of control.
5. Direct Set/Reset Inputs: The IC provides direct set (SD) and reset (RD) inputs for each flip-flop, enabling direct control over the outputs
