The SY100ELT22ZG-TR is a two-channel level shifter from Renesas that provides significant benefits to a wide range of applications. The devices can operate from low voltage logic levels to support lower power applications, and offer excellent flexibility for applications utilizing both higher power levels and lower power levels. As a dual-channel device, the SY100ELT22ZG-TR includes two independent level shifters, each with a distinct power supply. This feature allows the user to choose which power source should be used for each channel, making it easier to tailor the boards power schedule to specific application requirements.

The SY100ELT22ZG-TR is designed to translate CMOS level signals between different voltage levels with a maximum input range of 1.5V to 4.1V. A single device translates signals between two voltage levels, meaning that the SY100ELT22ZG-TR can be used to interface with different logic levels/ voltage differences between logic families, such as between 0.9V to 3.3V, 1.2V to 3.3V or 3.3V to 5V. In addition to its translations capabilities, the device also supports a wide operating temperature range from -40°C to +85°C.

The SY100ELT22ZG-TR is mainly used in low power applications and portable device applications, where reducing power by changing voltage levels is critical. In addition, the level shifter is used for interfacing different logic families and can target digital systems requiring fast switching times. Its minimal propagation delay of 110ps/83ps (for LVTTL/LVCMOS high->low and low->high transitions, respectively) makes the SY100ELT22ZG-TR suitable for applications that require low power and fast signal responses.

The SY100ELT22ZG-TR is equipped with features that provide further benefits. It has an Enable/Disable control with an input threshold of 2.5V, allowing users to control the operation of the device during low voltage logic levels. Additionally, the device is equipped with a Thermal Shutdown circuit, which protects the device and the application it is connected to in case of temperatures exceeding the recommended values. Finally, the device also has ESD protection of 2kV.

The SY100ELT22ZG-TR operates on the principle of logic-level-shifting. This means that the device is able to interpret one logic level and interpret it as another in order to match a different logic level system. This is enabled via two channels on the SY100ELT22ZG-TR: an input channel which receives the signal to be converted, and an output channel which converts the signal and generates the output signal. The signal is shifted from one voltage level to another based on the relative positions of the input pins and output pins.

This type of device is also referred to as a voltage-level translator, voltage-level shifter, or a translation overvoltage level shifter, to emphasize its complexity and differences to other level shifting devices. This is because logic-level-shifters can perform much more than just level shifting; they can also provide signal conditioning, data protocol translation, interfacing between mixed signal and dual signal protocols, and the inversion of signals.

In summary, the SY100ELT22ZG-TR is an ideal solution for low power, portable and mixed logic families applications. Its two independent channels provide added flexibility for applications and it has an integrated Enable/Disable control, Thermal Shutdown, and ESD protection. The SY100ELT22ZG-TR operates on principle of logic-level-shifting, allowing it to convert signals between different voltage levels while also providing additional features such as signal conditioning, protocol translation, and signal inversion.
