ON Semiconductor NLSV2T244DR2G Logic Level Translator

The NLSV2T244DR2G is a versatile, dual-supply, bidirectional logic level translator from ON Semiconductor. Designed for mixed-voltage digital systems, this device enables reliable voltage level translation between different logic levels ranging from 1.65V to 5.5V, making it an essential component for interfacing devices operating at different voltage levels within a system.

With its two-bit, non-inverting translator with tri-state outputs, the NLSV2T244DR2G ensures smooth communication between incompatible I/O standards. The translator's A ports are designed to track V<sub>CCA, which can be supplied at any voltage between 1.65V and 3.6V, while the B ports track V<sub>CCB, which accepts supply voltages between 2.3V and 5.5V. This flexibility allows for seamless integration of 3.3V to 5V or 1.8V to 3.3V logic signal domains, among others.

One of the key features of the NLSV2T244DR2G is its auto-direction sensing, which eliminates the need for a direction control signal. This not only simplifies circuit design but also reduces the risk of potential damage from contention on the data lines. Additionally, the device's power-off protection ensures that any floating input does not result in excessive current draw, thus protecting the device and the system.

The NLSV2T244DR2G is available in a compact, 8-pin SOIC package, making it suitable for space-constrained applications. Its robust design includes over-voltage tolerant I/Os, which can withstand input signals up to 5.5V even when the device is powered down. This feature enhances the durability of the translator and contributes to the longevity of the application it is used in.

With its wide operating temperature range and the ability to provide bidirectional voltage translation without the use of a direction pin, the NLSV2T244DR2G is ideal for a variety of applications, including but not limited to mobile phones, PDAs, GPS systems, and mixed-voltage systems in the automotive and industrial sectors.

Overall, the NLSV2T244DR2G from ON Semiconductor is a reliable and efficient solution for voltage level translation in multi-voltage digital systems, offering both versatility and ease of use for engineers and designers.
