The CD4093BPWG4 is an 8-pin integrated circuit belonging to the 4000 series CMOS logic family, which is a common variety of digital logic circuits used in a wide range of applications. This type of CMOS logic circuit has several advantages over other forms of logic, including low power consumption and high noise immunity.

The CD4093BPWG4 is electrically identical to the CD4093BCN and CD4093BLE due to its 8-pin DIP package. This device contains four independent 2-input NAND Schmitt trigger circuits which have an overall supply voltage range of 2V-18V. It has the ability to fare far better than conventional logic when exposed to long term direct sunlight and surges of current or voltage due to its built-in noise and voltage protection.

Application Field

The CD4093BPWG4 is generally used in logic applications in various fields such as industrial, automotive, communication, and consumer electronics. One of the main applications of the CD4093BPWG4 is in automotive applications since it provides excellent noise immunity, which helps prevent false triggering of the circuits due to electromagnetic interference.

In addition to automotive applications, the CD4093BPWG4 is also used in a variety of consumer electronics such as gaming systems and other portable devices. It is also commonly used in industrial applications as an interface for controlling relay outputs, and as a noise suppression for inputs connected to switches.

Working Principle

The CD4093BPWG4 is composed of four 2-input NAND Schmitt triggers, each with an overall supply voltage range of 2V-18V. It is designed to have the properties of both the CMOS and TTL logic families, meaning it can operate in both low and high noise environments.

The working principle of the CD4093BPWG4 is composed of two parts. The first part is a Schmitt trigger device, which has an internally generated hysteresis voltage. This voltage is generated by applying a bias voltage to the circuit, allowing the device to ignore any noise signals on the input. The second part is a CMOS transistor, which provides a way to turn the Schmitt trigger off when not in use and reduce power consumption.

Both parts of the device use an N-channel MOSFET in their respective circuits. When the logic level of the input pin is more than a certain threshold voltage, the output of the device is HIGH. When the logic level of the input pin is below the same threshold voltage then the output of the device is LOW.

The CD4093BPWG4, due to its CMOS characteristics and Schmitt trigger properties, has very low power consumption and high noise immunity. This makes it an ideal choice for a variety of logic applications.
