SY10EPT20VKG is a typically logic-level translator, which is designed to help two voltage domains with different logic levels communicating with each other. By providing an adjustable output voltage, it can reach the appropriate translation threshold between the two logic levels. The package is pinned out as 5-lead SC70, 8-bump micro SMD (X2505) and 8-lead TSSOP packages.

SY10EPT20VKG operating environment is flexible, working temperature range between -55°C to 125°C. The power supply voltage VCC can range from 1.1 to 5.5V and the output voltage is adjustable. With such wide adjustable range, this level shifter can help those 5V CMOS logic design to communicate with other 1.8V logic system, 3.3V logic, 1.5V logic or any other different logic levels. It also realizes a wide average and peak current, allowed peak current is 0.7A and the average current is 0.4A at VCC=1.8V, 2.5A peak for VCC=5.5V, and maximum average current of 1.2A.

Breifly, SY10EPT20VKG core logic is a HCCT (High−Current Cross−Coupled Translator). A HCCT consists of two saturated devices that turn on when their respective inputs go low, allowing current to flow in either direction between the regimes. The output in the highspeed regime closely follows the input in the slow regime.SY10EPT20VKG uses the same configuration, but with the addition of a voltage regulator which can be adjusted to create proper logic level translation between the regimes. The device works as a bi-directional level shifter that responds to the slow logic input while the transistor maintains a regulated output voltage.

The device acts like an open-collector output buffer. When the active low enable is high, the internal transistors are disabled, disconnecting the two domains, so the input and output are in high-impedance state.The device supports adjust the output voltage to create a noise-free translation threshold between two runs of logic. This is due to the way that noise sources can be identified in the logic, which can cause devices to toggle. By increasing the voltage on the output, the noise voltage source can be attenuated and the toggle rate can be reduced resulting in a cleaner, noise-free logic translation.

The output of SY10EPT20VKG can also be driven by an external voltage level. This allows the device to be used for different application in different environments, such as switching applications, clock conditioning, and buffering. In addition, the device includes built-in protection circuit, over current and over voltage protection ensure safety while operating in industrial climatic conditions.

In conclusion, SY10EPT20VKG logic-level translator is an effective and reliable device that can provide bi-directional data transfer between different voltage levels of logic systems. It provides adjustable input voltage output and a safe environment by the protection circuit. The device is ideally suited for applications that require high current level shifting, buffering and switching.
