The CD74HC190EG4 is a divider-type counter in the 74HC Logic family manufactured by Texas Instruments. It is an 8-bit synchronous binary counter that features a wide operating voltage range from 2.0V to 6.0V. This device is designed to count the number of clock pulses that arrive at its input in a sequence based on fractional divisions of the applied clock signal. The divider type counter will count up, then reset and continue counting.

In its standard form, the CD74HC190EG4 is an 8-bit counter, meaning that it will take 8 clock pulses or counting edges before it resets its output signal. The counter can be configured to operate in either an up-counting or down-counting configuration, depending on the logic inputs and clock signals applied to the device. The counter has four output signals that are driven high during the counting process.

The CD74HC190EG4 is primarily used in data acquisition and process control applications. It is often used to measure frequency and time, as well as to divide down clock signals in order to synchronize different logic systems. The device is also used in counter and divide applications such as totalizers, sequencers, and time-delay circuits.

The CD74HC190EG4 counter operates by taking an input signal, and then counting or dividing it down depending on the logic signals applied to the device. The counter will follow a sequence of counting up and down depending on the control signals and select pins that are applied to the device. A reset signal can be applied to reset the counter, and an output signal will be driven high during the counting process.

The CD74HC190EG4 counter is a simple and cost effective counter solution for a variety of applications. The device is suitable for use in conditions ranging from moderate to high temperatures, and consumes only a few mW of power. Additionally, the input signal is protected from ESD thanks to built-in protection diodes.

Overall, the CD74HC190EG4 is an excellent choice for applications where time, frequency and divide down logic solutions are necessary. With its functional flexibility, low power consumption, and outstanding reliability, the CD74HC190EG4 offers a great value for any application.
