The CD74HC390E is a dual synchronous binary up/down counter with programmable self-clocking. Further, it also has an integrated oscillator. It is capable of dividing incoming waveforms down to a clock frequency accurately, using the adjustable counter range. This makes the CD74HC390E ideal for use in automotive, instrumentation, communication, and industrial control applications.

In the application field, the CD74HC390E is well suited for automotive, instrumentation, communication, and industrial control applications. Its ability to divide a waveform down to an accurate frequency makes it perfect for applications that require precise timing. Additionally, it has an integrated oscillator, so that external components are not necessary.

The CD74HC390E is a synchronous binary up/down counter that counts in binary bits. It has two 4-bit counter blocks and is operated through rising edge transitions of its clock. Counting occurs after each clock pulse and is done in a "ripple carry" mode, i.e., a carry output is generated each time the 4-bit block is full. This carry output is then connected to the next 4-bit block as an input.

The CD74HC390E offers a degree of flexibility not seen in many other counters. It has an adjustable counter range, so that the counter can be scaled up or down, depending on the application needs. It also has the ability to be loaded or reset via its control input. Furthermore, there is a cascade mode, which allows for two of these counters to be connected together for higher-bit counts.

In operation, the CD74HC390E is driven by the rising edge of its clock input. When the clock goes high, the counter starts counting up or down, depending on the state of its up/down input. As it counts, the count is outputted on its output pins in binary form. It will continue counting until it reaches its upper or lower limit, at which point the output will reset to zero and start counting again.

The CD74HC390E has various features that make it well suited to use in automotive, instrumentation, communication, and industrial control applications. Its adjustable counter range makes it ideal for situations that require precise timing. Moreover, its cascade mode allows for two of these counters to be connected together for higher-bit counts. Finally, its control input provides the ability to load or reset the counter, which allows for manual programming of the counter.

In summary, the CD74HC390E is a dual synchronous binary up/down counter with a programmable self-clocking ability and an integrated oscillator. It is well suited for applications that require precise timing and is ideal for use in automotive, instrumentation, communication, and industrial control applications. Its flexible features, such as adjustable counter range, control input, and cascade mode, make it a versatile and reliable device.
