Logic translators and level shifters are among the most useful and versatile Integrated Circuit (IC) devices available. The SY100ELT20VZI is a superb example of the level-shifting products now available on the market, and the scope of its application field and its working principles are perfectly suited for the current trend of smaller, faster, and more efficient electronic components.

The SY100ELT20VZI is an essential device for safely crossing electrical interface boundaries, as well as simplify some of the headaches associated with electrically isolated or complex supply voltage requirements. It is a low-power, low-voltage bidirectional level-shifter IC, with a very high data rate capability. It can easily convert low-voltage TTL and CMOS logic signals of 3.3V, 2.5V or 1.8V to higher standard logic levels of 5V and vice versa, making it ideal for interfacing between digital ICs, devices, and components.

The SY100ELT20VZI is composed of two main components—a high level shift block and a low level shift block. The high-level shift block shifts the voltage from low TTL Logic (3.3V, 2.5V or 1.8V) to 5V; this output may then be fed directly back into the low level shift block. The low level shift block can then convert the 5V signal to low TTL logic level (3.3V, 2.5V or 1.8V). The bidirectional capability allows signals to be shifted in either direction, making it a superb tool to solve the problem of mismatched logic levels.

The SY100ELT20VZI can also function as an auto-direction sensing level-shifter, meaning it can determine direction of signal flow based on the first logic level. As such, the SY100ELT20VZI is perfect for applications such as microprocessor bus systems, digital signal processor bus systems, digital logic circuits, and complex interfaces.

In addition to its bidirectional level-shifting features, the SY100ELT20VZI offers a very fast switching response time of typically 3ns, allowing for high-speed signals to be processed without any data loss. The device is also rated at a very low power consumption of 4mA, making it one of the most economical ICs in the market.

Finally, the SY100ELT20VZI offers the advantage of being tested at a variety of operating conditions to ensure a high level of reliability. It is rated to operate between 0°C and 70°C and work under a wide input range of 1-14V. Being a low-voltage logic and level shifter, the SY100ELT20VZI is also inherently immune to electrostatic discharge (ESD) up to 8kV and latch-up up to 200mA.

In conclusion, the SY100ELT20VZI low-voltage bi-directional level shifter is an extremely useful and versatile device, perfectly suited for the trend of miniature electronic components and the need for transmitting high-speed digital signals without data loss. It provides a simple, yet powerful solution for problems posed by mismatched logic levels and its low power consumption and high immunity to ESD and latch-up make it ideal for a variety of applications.
