MC14042BCPG: Application Field and Working Principle

The MC14042BCPG is a logic component that facilitates data retention and easy manipulation. It belongs to a particular logic family called Latches. Latches are used in a number of applications ranging from recording data, to providing an indicator of a certain condition. This component from ON Semiconductor can be invaluable in operations that are low-power and require fast response times.

What is the MC14042BCPG

The MC14042BCPG is a combination of six Latches designed for low voltage operations. It consists of an array of two 3-state buffers and two voltage detector circuits. The component also contains an active low reset (R) input from which an output ‘L’ will be generated. Additionally, the component has a enable pin that when set to logic 0, will disable all the outputs of the component.

Operating Voltage

The operating voltage of the MC14042BCPG is around 4.5 volts. This voltage should be stable, which is within the recommended operating temperature range of 0°C to 70°C. With operating voltage of 4.5 volts and a supply current of 500 uA, the component is suitable for a low-power operation.

Features and Benefits

The features of the component are few. However, with the implementation, the component packs more punch than it looks. The component offers two voltage detectors and two 3-state buffers. This combination offers a robust logic system from which applications can be built around. The component is also designed to be used with other components from the MC14042BCP line.

Other benefits include fast response time, low-power operation, wide voltage operating range and high noise immunity. With its small package size of 14 pins, the component will occupy a minimal portion of the available real estate and can easily be wired into existing circuits. The component also contains an enable pin, providing the option of comfortably disabling the component, if necessary.

Applications

The MC14042BCPG is used in a number of applications. From data retention to providing an indicator of a certain condition, the component can be used with a wide range of applications. Examples of where the component can be used include: in digital systems, digital logic applications, common byte memory circuits, IC enable/disable and logic level conversion. Another use is in measurement and test equipments as a low-power indicator latch.

Working Principle

The component works by connecting an input signal to the input pins of the component. Once the component is enabled, when the input signal is applied, the output pins will activate and the data will be stored until the component is reset. The component contains two voltage detector circuits, which will detect any differences between the input signals and the applied voltage. When a difference is found, the component processes the input and the appropriate output is generated. The component also has an enable pin which, when set to logic 0, will disable all outputs of the component.

Conclusion

The MC14042BCPG component offer users a hands-on alternative to data recording and manipulation. The component is highly compatible with a number of applications and can benefit users in an array of environments. With its low-power operation, fast response-time and wide voltage operating range, the component is more than capable of providing an effective data retention system.
