Logic - Translators, Level Shifters are widely used in various fields. PI4GTL2034LEX is very popular in the industry and its application field and working principle will be discussed in this article.

Introduction of PI4GTL2034LEX

PI4GTL2034LEX is a four-channel level translator with multiple voltage, direction and input/output combinations. It is specifically designed to meet the needs of the latest processor, memory and other I/O port designs that require 1.238V to 3.3V or vice versa for low-power and low-voltage operation. This device combines two 4-to-1 movement sections, one is responsible for the connection of 1.8V logic and the other section can switch between 1.238V and 3.3V logic level.

Application Field

PI4GTL2034LEX is suitable for various applications, such as automotive modules, Power over Ethernet (PoE) devices, gaming controllers, medical and industrial sensors, security and surveillance systems, small size and high speed point of load (POL) regulation. It can also be used in other low and medium power applications that require level translation between multiple voltage domains. In addition, this device is CE compliant, RoHS compliant and UL recognized.

Working Principle

PI4GTL2034LEX works on the principle of voltage level translation. The voltage translation is done between the input and output pins and the internal logic is used to perform the translation. This logic ensures the voltage at the output pins is equal to the input pins, or within the specified range, after the level translation. The device contains four independent 4-to-1 level translators and each of the 4 channels has two independent configurable voltage levels. This feature makes the PI4GTL2034LEX suitable for various applications with different voltage requirements.

The translators have an internal latch type logic circuit, where the input and output voltage levels can be different. The device also has a configurable delay time to ensure the correct logic is given to the device itself by the input logic. The delay time is adjustable and can be set up to 0.01μs. The device also has configurable rise and fall time, which can be adjusted up to 150ns.

Conclusion

In conclusion, PI4GTL2034LEX is a four-channel level translator with multiple voltage, direction and input/output combinations. It is suitable for various applications, such as automotive modules, Power over Ethernet (PoE) devices, gaming controllers, medical and industrial sensors, security and surveillance systems, small size and high speed point of load (POL) regulation. It works on the principle of voltage level translation and it has an internal latch type logic circuit, where the input and output voltage levels can be different. It also has a configurable delay time and rise and fall time. Therefore, it is a great choice for applications which require level translation between multiple voltage domains.
