CD40193BEG4 is a type of BCD decade counter. It is a synchronous four-stage binary counter capable of counting up 4 different numbers in a predefined sequence. It is also known as a Divide-by-10 counter or a BCD (binary-coded decimal) counter because it is capable of counting from 0 to 9 in binary form. The CD40193BEG4 is part of the 4000 CMOS logic family designed by Texas Instruments with the use of CMOS technology. This family of logic devices is characterized by low quiescent current, low noise levels and an operating temperature range of -55C to +125C.The CD40193BEG4 is an extremely versatile device which can be used in a multitude of applications including instrumentation, industrial, telecommunications and consumer applications. Its major features include low power consumption, low quiescent current, static operation, and low offset voltage on the outputs. Its applications include car alarms, motor control, digital audio and digital signal processing.The CD40193BEG4 can be used in a variety of ways and it is important to understand the working principle of the device in order to use it in the most effective way for a given application. The device is composed of four stages of ripple counter. The first stage or the input stage is the asynchronous reset input; it is responsible for the initial conditions of the counter. The next three stages are the synchronous control inputs or CLR, CAR and QC which are responsible for the synchronization of the counting sequence, where CLR is responsible for resetting the counter, CAR is responsible for counting and QC is responsible for setting carry out.Combined together, these inputs are responsible for the counter going through a predefined sequence of four states: 00, 01, 10 and 11. The rate of change in this sequence can be controlled by the selection of a suitable frequency of the clock input. The CD40193BEG4 has an active low reset input, the CLR and a QT output. The CLR is used to reset the counter to all binary zeros while the QT is an asynchronous output that will remain logic high whenever the count is 10.The CD40193BEG4 also has active low count enable and active low output enable inputs. The count enable signal is used to activate the counter, allowing it to continue the cycle from state to state. The output enable signal is responsible for enabling or disabling the outputs of the device. This is useful for applications where the user wants to save power.The most common applications of the CD40193BEG4 include car alarms, motor control, digital audio, digital signal processing and any application that requires accurate time measurements or event counting. It can also be used as a basic frequency divider to divide the input frequency into a lower frequency output.In summary, the CD40193BEG4 is a BCD decade counter which is capable of counting up to four different numbers in a predefined sequence. It has low power consumption, low quiescent current and extended operating temperature range. The device can be used in a variety of applications, including car alarms, motor control, digital audio, digital signal processing and any other application that requires accurate time measurements or event counting.
