The ISL3179EIRZ is a series of high voltage, low power bi-directional I2C/SMBus voltage translator/repeaters. It is used to translate a logic level signal from one logic family to another as well as the ability to drive signals. The devices are designed for RS232 level shifting, VDDIO level shifting, I2C level shifting, ACPI chip sets, 3V to 5V and 5V to 3V applications. In addition, the part could also be used for low voltage applications.

The ISL3179 applications are numerous. It is used primarily as an I2C/SMBus voltage translator, voltage repeater, level shifter, and logic level converter between 3V and 5V logic levels. The device can also be used to shift the logic levels between different families of logic such as ECL, TTL, CMOS, and open collector logic. It is also used in RS232 level translation, PCI Express to PCIe translation, low voltage switching, and bridge between high voltage and low voltage applications. The part is also used in Intel P3 and Telecom communication interface.

The ISL3179EIRZ has several distinct advantages over other translators. It has very low input/output capacitance, making it suitable for low voltage applications. It has very low power consumption, which makes it energy efficient and well suited to portable devices. The part has very fast switching speeds, providing enhanced system performance. The device supports up to 400KHz speed for I2C interface, and 10 MHz for SMBus interface. It is also RoHS compliant and available in a variety of packages.

The ISL3179EIRZ devices incorporate a number of features that make it ideal for a variety of applications. The device’s slew rate is configured via a separate pin, allowing users to adjust the slew rate as needed. The device also features ESD protection levels up to 2KV, making it suitable for applications exposed to environment that may lead to ESD events. The device also features shot-through current protection, over voltage latch off, and thermal shutdown.

The ISL3179EIRZ is comprised of two gateway circuits, one on the high side and the other on the low-side, each of which is connected to the logic level I/O pins on either side. The gateways act as an isolator, allowing the logic level signals from either side to be translated to a different voltage level. The device will automatically adjust the voltage levels as per the VDD and VDDIO value set in the chip, eliminating the need for any external components. The high and low-side gateway circuits are connected using an internal bus which is further connected to the on-chip EPROM, providing non-volatile storage.

The ISL3179EIRZ is a very versatile device and is used in a wide range of applications, from voltage level translation and level shifting in communication, computing and consumer electronics to signal transfer between different logic families. The device’s low input/output capacitance, low power consumption and fast switching speeds make it an ideal choice for all types of applications.
