ON Semiconductor MC74AC109DR2 Dual JK Positive Edge-Triggered Flip-Flop

The ON Semiconductor MC74AC109DR2 is a high-performance, dual JK flip-flop integrated circuit that features individual J, K, set, reset, and clock inputs for each flip-flop. This component is designed for use in a wide range of digital applications where reliable edge-triggered state changes are required. Its positive edge-triggered operation ensures precise control over the timing of state changes, making it an ideal choice for timing circuits, counters, and control systems.

Constructed with advanced CMOS technology, the MC74AC109DR2 offers a combination of low power consumption and high speed, operating at a voltage range of 2V to 6V. This makes it suitable for battery-operated devices and portable electronics, as well as high-speed systems that require efficient power management. The device is characterized for operation from -55°C to 125°C, ensuring reliable performance across a wide range of environmental conditions.

Each flip-flop in the MC74AC109DR2 has independent inputs including a direct clear (CLR) and a direct set (SET), which are asynchronous. This means that the flip-flop can be set or reset at any time, regardless of the clock input, providing additional flexibility in circuit design. The JK inputs, when both high, allow the flip-flop to toggle on each clock pulse, adding versatility to the possible logic functions that can be implemented.

The device is provided in a space-saving SOIC-16 package, which is ideal for applications where board space is at a premium. The MC74AC109DR2's surface-mount package allows for efficient assembly in modern printed circuit board manufacturing processes, contributing to a reduction in overall production costs.

ON Semiconductor's commitment to quality ensures that the MC74AC109DR2 meets stringent industry standards for performance and reliability. Whether used in complex digital systems or simple timing applications, this dual JK flip-flop provides designers with a robust and flexible component that enhances the functionality and stability of their electronic designs.

Overall, the MC74AC109DR2 from ON Semiconductor is a versatile and reliable choice for any application requiring a dual JK positive edge-triggered flip-flop.
