The ISL3035EIRTZ is an integrated circuit designed for logic-level shifting and isolating between different voltage domains and power sources. It is designed to handle any combination of 3V and 5V logic levels with suitable driving strength. It is capable of translating many standard logic level signals between 1.2 V and 5.5 V and works with a VCC supply voltage ranging from 1.5 V to 5.5 V.

The ISL3035EIRTZ is a low-voltage, low-power logic translator with integrated ESD protection. It is a four-channel, bi-directional, logic translator, allowing mixed logic levels to be translated and converted between two separate power domains. It has four bits of bidirectional data transfer and the direction of each bit can be individually selected. It is also configured to operate in both the high-impedance and active states. The output drive current is selectable between 4 mA, 6 mA, and 8 mA.

The ISL3035EIRTZ features different protection levels which make it suitable for various application needs. It features ±15 kV HBM ESD protection and overvoltage tolerant inputs. It also has programmable partial power-down, which allows its driver VCC to be reduced to less than 1.0 V while still maintaining the logic level of its output pins. Furthermore, it has built-in active pull-up and pull-down with programmable rise time and fall time, which gives it a wide operating range.

The ISL3035EIRTZ uses a few logic pins to control the data translation, depending on the direction of the translation. The logic pins used are ENABLE, SL1, and SL0 which will determine the direction of the translation. When the enable pin is low, the device will be in a high impedance state and all the inputs and outputs will be at the same voltage level. When the enable pin is high, the other two logic pins will determine the direction of the translation.

The ISL3035EIRTZ also features a slew rate control pin, which lets the user program the slew rate of the device. A slower output transition rate will result in better noise performance. However, it also reduces the clock frequency that is supported by the device. It is important to accurately set the slew rate control pin on the device to ensure the best performance.

In terms of working principle of ISL3035EIRTZ, it works by translating the logic signals from one domain to another. Two independent VCC input pins provide power to each logic domain. The voltage range of VCCA and VCCB pins are determined by the voltage inputs to the logic pins. All the logic pins will have the same logic level and logic family. When the enable pin is pulled high, the device will use the SL1 and SL0 pins to determine the direction of the translation.

The ISL3035EIRTZ can be used in various applications, such as interfaces between system buses, memory read/write, peripheral bridges, and digital audio data transfer. It can also be used in automotive and industrial applications. It provides a small size solution for low-voltage applications, as well as for protection from transients. The ISL3035EIRTZ is an ideal choice for low-power, high-speed, and low-cost applications.
