As a counter, the device can simultaneously count the frequency of the signal and store the count within its memory. Furthermore, it can also divide or multiply by any integer from 1 to 65535 and modulus up to 240. Its signal processing feature includes a wide range of functions such as signal regeneration or threshold detection. As a control device, the 74HC390D,652 can be used as a motor control and for machine automation.

In terms of working principles, the 74HC390D,652 is an electrostatic sensitive device, which consists of eight registers and eight addressable memory locations. The working principle of the 74HC390D,652 is based on the interaction of its addressable memory locations and the associated registers. Each of the eight registers can be configured independently of the others, creating a \'register state\' which is then used as a basis of operation. This allows the device to be used in multiple applications.

The memory locations within the device are assigned to the eight registers by use of the eight register select pins. Each register is then assigned to an output signal by the output select pin. The data bits of the registers can be altered by the programmable control inputs. This is used to control the signal output of the device. The device also has a reset pin, which can be used to clear any portion or all of the memory when necessary.

Furthermore, the 74HC390D,652 is also capable of temporarily storing information, which is useful for saving device output after a power failure or other unexpected situation. The device is powered by a +Vcc and ground. In general, the 74HC390D,652 is quite reliable and easy to use for many applications.

In conclusion, the 74HC390D,652 is an advanced logic device which offers a wide range of features, enabling it to be used in a variety of applications. With its advanced logic configuration and flexible programming, the 74HC390D,652 is capable of counting, dividing, and signal processing. Furthermore, the device has a wide range of output logic configurations and is capable of temporarily storing information when necessary. All of these features make the 74HC390D,652 an ideal choice for many applications that require precise accuracy and a fast response time.
