What Does a Level Shifter Do?
Level shifters are also referred to as voltage-level translators or logic-level shifters. This device is used to translate signals from a voltage domain or logic level to another to check for the compatibility of integrated circuits with different voltage requirements. In most cases, the circuit is used to translate shifts between 5V and 3.3V; however, you can use it on other voltages as needed. When using a level shifter, you need to consider the following factors:
Hardware Implementation of Level Shifters
Level shifters have numerous implementations in digital electronics. This circuit is used in systems to bridge domains between sensors, logic, processors, and other circuits. However, when it comes to hardware implementation, there are two main uses:
Application of Level Shifters
Level shifters have numerous applications across several industries. Their ability to resolve the voltage incompatibility between different parts of a system makes them an invaluable component in a digital device. These circuits are mostly used in interfacing legacy devices with varied applications in audio codecs, UARTs, SIM cards, SD cards, and CF cards.
