74LS107 Product Details

The 74LS107 is a dual J-K flip-flop integrated circuit (IC) produced by Texas Instruments. J-K flip-flops are a type of digital circuit that can be used to store binary data and implement a wide range of sequential logic functions.

The 74LS107 contains two independent J-K flip-flops, each of which has a data input (J and K), a clock input (CP), a clear input (CLR), and two outputs (Q and Q'). The flip-flops can be used in a variety of applications, including shift register design, frequency divider circuits, and binary counters.

The 74LS107 is designed to operate at high speed and with low power consumption, making it ideal for use in digital systems that require fast operation and efficient power usage. It is also designed to be highly reliable and stable, making it a popular choice for use in a wide range of applications.

The 74LS107 is widely used in digital circuits and is available in a variety of packages, including DIP (dual in-line package) and SMD (surface-mount device) packages. It is an older device that has been replaced in many applications by newer, faster, and more power-efficient components, but it is still widely used in many older systems and for educational purposes.
