74ACT109SC

74ACT109SC Description

The 74ACT109SC is a dual JK-type flip-flop IC designed for high-performance digital applications. Manufactured by Fairchild Semiconductor (now part of onsemi), this logic IC chip offers robust performance and reliability. It features a clock frequency of up to 210 MHz, ensuring fast operation and efficient data handling. The maximum propagation delay is 11ns at 5V with a maximum load capacitance of 50pF, making it suitable for high-speed circuits. The quiescent current is a mere 20 µA, which is ideal for low-power applications.

Each flip-flop element in the 74ACT109SC is capable of handling one bit of data, and the output is complementary, providing both true and inverted outputs. The flip-flops are triggered on the positive edge of the clock signal, ensuring precise timing control. The supply voltage range is 4.5V to 5.5V, making it compatible with standard 5V digital systems. The device is housed in a surface-mount package, specifically a tube, which facilitates easy integration into modern PCB designs.
