Introduction to Logic - Translators, Level Shifters, and SY100EL91LZC-TR

Logic-level translators and level shifters are two classes of devices commonly used to switch devices on or off. Although they share many similarities, there are key differences between the two that should be noted. Logic-level translators are digitalte-logic gate interface circuits, which are used to convert a "low" logic level (such as 0V) to a "high" logic level (such as 5V), and vice versa. They accomplish this by using an open collector or open drain output. Level shifters, on the other hand, are used to translate one voltage level from another. Examples of level shifters include voltage biasing, which is used to convert a high-impedance logic level to fit a low-impedance logic level, and "voltage boost" (or voltage elevation), which is used to transfer a low-voltage logic level to higher-level supplies. One popular application of logic devices is to allow communication between two different devices, such as a microcontroller and peripheral component, which operate on different logic levels. In this application, the logic-level translator or level shifter acts as a bridge between the two devices, allowing them to communicate. One of the most common logic-level translators and level shifters used in these applications is the SY100EL91LZC-TR. This device is an integrated voltage-level translator for CAN-based systems. It features an adjustable translated voltage between 0.3V and 3.0V and can be used to provide voltage translation on multiple pins simultaneously.

Features of the SY100EL91LZC-TR

The SY100EL91LZC-TR logic-level translator and voltage shifter is ideal for use in a variety of applications, including automotive, communication, computing, consumer, and industrial applications. Its integrated circuit design facilitates multiple-pin simultaneous voltage translation and supports a wide range of voltages (up to 3.0V) with very low power consumption. The SY100EL91LZC-TR features an integrated charge pump and an adjustable bias current for ease of use. The charge pump is designed to reduce voltage drops and eliminate the need for external supplies. Additionally, the charge pump can provide voltage bias for enhanced signal transmission and reduce noise interference. The integrated bias current adjustment allows for precise adjustment of the bias voltage for different applications. To further reduce signal interference, the SY100EL91LZC-TR features low-voltage switching between the input and output pins. This allows the device to switch from one logic-level to another quickly and without the risk of signal interference. Additionally, the device features an integrated thermal-sensing circuit and ESD protection, which help to ensure prolonged device life and reliable operation.

The working principle of the SY100EL91LZC-TR is simple. The device is connected to the two devices that need to be able to communicate, and then the device translates the logic levels between the two devices. This allows the two devices to communicate regardless of which logic level they are using. Additionally, the charge pump helps to reduce voltage drops, and the integrated bias current adjustment allows for more precise adjustment of the bias voltage for different applications.
