Logic-Translators, Level Shifters are one of the most commonly used signal conditioning products in electronic circuit design because they can bridge the gap between signal levels of different electronic systems. This article will illustrate the application field and working principle of MC100LVELT23DG with which designers can have a better understanding of the logic-translator level shifter.

MC100LVELT23DG is a dual bidirectional logic level translator designed for electronic applications requiring a high performance, low power solution between two voltage buses. The chip is a dual 8-bit level translator with two independent level shifting channels, featuring pull-up resistors on the outputs for open-drain applications. It supports two logic voltage levels, such as 1.2V and 2.5V or 1.8V and 3.3V. MC100LVELT23DG is available in SOIC, TSSOP and VSSOP packages.

The application field of MC100LVELT23DG includes systems requiring automatic voltage level translation between incompatible voltage buses, such as consumer electronics, industrial automation, medical electronics, and automotive applications where data/signal conversion is necessary. It also provides an operating voltage range of 1.65V to 3.6V, and can be used in applications where either 1.8V or 3.3V is used as the common voltage.

The working principle of MC100LVELT23DG is relatively simple. When the chip\'s enable signal is asserted, the voltage level of the input signal, (Vin) will be translated and outputted onto the other side of the chip with a different voltage, (Vout). The voltage level of the output signal depends on the voltage levels of the two buses, so it can be configured for either 1.2V~2.5V, or 1.8V~3.3V ranges. The level shifter also has a low power consumption of 200µA (typical).

To sum up, MC100LVELT23DG is an ideal partition bridge betweentwo voltage domains with its bi-directional logic level translation and low power consumption feature, making it the perfect choice for a variety of signal conditioning applications.
