74HC14DR2G Datasheet/PDF74HC14DR2G is a type of integrated circuit (IC) that is used mainly as a digital inverter and buffer. It belongs to the Logic - Gates and Inverters family of ICs. It is composed of a hex inverter gate, with Schmitt triggers, made with a PMOS and an NMOS transistor on each gate.
74HC14DR2G has a wide range of applications in many modern electronics systems. Its high level of integration allows it to bring several logic functions into one chip, making it a versatile and cost-effective solution for many applications. It is popular in automotive, industrial, and consumer applications.
Application Field
The most common application area of 74HC14DR2G is as oscillator for generating and inverting digital signals. Its reliability and high-level of performance makes it a great solution for applications where digital signal integrity must be maintained. It is also used in logic level conversion between different families of ICs, since its wide supply voltage range allows it to interoperate with many different families of ICs.
It is used in security systems and audio systems as part of delay lines, motor controls, and digital logic circuits. It is often found in automotive applications, providing just enough logic to perform noise filtering, glitch suppression, and logic level conversion.
Working Principle
When a positive going trigger signal is applied to the input of the 74HC14DR2G, it will cause the input to become low, causing the corresponding output to be inverted. When the positive going trigger signal is removed, or the input goes low, the output will become high. This is called a Schmitt trigger action.
The 74HC14DR2G has six of the Schmitt trigger inverters, all sharing the same power supply line. It also has an open collector output on each gate, which makes it easy to connect each gate to several different outputs, allowing for an easily expanded logic inverter.
It also has an internal protection diode for each input and output. This provides protection against electrostatic discharge (ESD), voltage spikes, and external interference. This feature makes it one of the most robust and reliable logic ICs available.
The 74HC14DR2G is a great choice for applications where robustness and reliability are required. Its wide operating range and tremendous levels of integration make it an ideal choice in automotive, consumer, industrial, and security applications. It is also cost-effective and easy to use, making it a great choice for most digital logic applications.
