The CD4093BE is a Quad 2-Input NAND Schmitt trigger which is made up of four NAND gates. It was developed by Texas Instruments and is part of their 4000 family of digital integrated circuits. It is a versatile integrated circuit with many applications. This article will discuss the application fields of the CD4093BE as well as its working principles.

Application Fields

The CD4093BE is most often used as an oscillator, or generator of an AC signal (since it provides both a high and a low output enablement). It is also used in analog circuits as a comparator, an amplifier, and an active filter. CD4093BE can be used for applications such as analog switch, gain switch control, voltage regulator control and error detection. Some specific tasks the CD4090BE can be used for are regulated power supplies, multiplexers, op amp circuits, time base and frequency generators and trigger circuits.

Working Principles

The CD4090BE is comprised of four identical NAND gates. Each NAND gate has two input pins and one output pin. The inputs are Schmitt triggers which provide clean signal switching when used with a repetitive signal. All four NAND gates are connected in the same configuration so they share the same logic operation regardless of their individual positions.

The output of the CD4090BE will provide a digital signal when one or both of the inputs are at a logical high. If both inputs are logical low, the output will remain low. When both inputs are high, the output will go low as a result of the NAND gates' AND operation. This output can be used to trigger a clock or other digital signal.

In order to use the CD4090BE in oscillator applications, one of the two inputs must be connected to the output. When used in this way, the output is almost always high unless both inputs turn low. As the input turns from low to high, the output will turn from high to low, thus producing a repeating cycle. This cycle will continue until the input turns low and the output goes low.

The CD4090BE is a versatile integrated circuit and has a wide range of applications. Its four NAND gates and Schmitt triggers make it possible to use as an oscillator and/or a comparator, as well as for multiplexing, switching, and number of other tasks. Understanding the basic working principles of the CD4090BE can help engineers design creative and efficient applications that meet the needs of their project.
