CD74HCT390M96 is a dual 4-bit programmable ripple up/down counter designed for C-MOS/TTL/DTL applications. It is a highly configurable device with an internal synchronous or asynchronous reset, termination and data transfer capability. The CD74HCT390M96 is an industry-leading device for a wide range of applications such as embedded process control, timing and logic applications in automotive, aviation and consumer products.The main features of the CD74HCT390M96 are its versatility and configurability, allowing for the implementation of a range of solutions. The device contains two 4-bit counters, each with their own reset, clock and data structures. Each of the counters is highly configurable and can be configured for synchronous, or asynchronous operation. The device also provides a data transfer function and an internal reset function.The versatile nature of the CD74HCT390M96 allows for its usage in a wide range of applications. It can be used for counting, frequency division, modulo counting, interval counting, and pulse generation and detection. In addition, it can be used for applications that require precise timing, and precise pulse counting.ApplicationsThe CD74HCT390M96 is widely used in a wide range of applications. Typical applications include automotive (Dashboard and Control systems, Dashcam, Radios, Cruise Control), aviation (Air Traffic control systems, navigation, Autopilot), consumer products (Bluetooth headsets, VR headsets, fitness trackers, gaming consoles) and embedded process control systems.The CD74HCT390M96 can also be used in various types of industrial automation, such as for monitoring and controlling the production process. The device is also used in medical devices, communication systems, and other applications that require counting and exact timing.Working PrincipleThe CD74HCT390M96 is designed to count or divide down a clock signal. The device is composed of two 4-bit counters, each of which has their own reset, clock and data structures. It is this data structure that facilitates the asynchronous or synchronous operation of the device.The device has the ability to control the number of counts, or pulses, the device will count or divide down. This number is called the Modulo. The Modulo is programmed into the device when the device is powered on. This is done by programming the appropriate number of divisions or counts in the data structure.When the device receives a clock signal, it begins counting or dividing down the signal with each pulse. As the device counts down, it will generate either a count or a divide-down signal. This signal is output externally by the device. The device will continue to operate in this manner until the programmed Modulo value is reached, at which point the pulse sequence is reset and the process begins again. The CD74HCT390M96 is a highly configurable and versatile device. Its design allows for the implementation of a wide range of applications, from simple counting and frequency division to more complex pulse generation and detection. The device is suitable for a variety of automotive, aviation, and consumer applications, and is also widely used in industrial process control, medical, and communication systems.
