ISL3179EIBZ

ISL3179EIBZ is a high speed, 3.3V logic signal, single channel bi-directional level shifter designed to move signal between two different voltage domains. It supports both TTL (Transistor-Transistor Logic) level and LVTTL (Low Voltage TTL) and is available in space-saving 10-lead MSOP (Micro Small Outline Package).

With a unique high-impedance receiver, the ISL3179EIBZ device is desgined to minimise noise and help eliminate ground looping and system noise coupling. The driver output is programmable to support either 0.8VAC or 0.2VAC, and has a low power mode which can be enabled to minimise power consumption.

The ISL3179EIBZ device is ideal for applications such as powering bidirectional communications transitioning between the two domains, without the need for additional components. It can be used in a variety of discrete applications, such as bidirectional bus level shifting, that require full-duplex, tight timing requirements to ensure reliable communications. The device is also suitable for automotive and industrial applications, as it is highly integrated and requires minimal external components.

In terms of working principle, the ISL3179EIBZ operates on the same principle as a Schottky Diode. It uses a diode to guide the current from the higher voltage domain to the lower voltage domain with a resistor to limit the current flow. On the other end the device is connected to the lower voltage domain, with resistors connected to the input and output pins to limit the current flow.

The ISL3179EIBZ works by allowing the two input signals to transition between two different voltage domains without the need for additional components. When the input voltage is greater than the output voltage, the current flows through the diode and the resistor, while when the input voltage is lower than the output voltage, the reversed current flow through the diode will be limited by the resistor.

The ISL3179EIBZ application field is very broad and it can be used in a variety of configurations. It can be used in automotive, industrial and residential applications, since it is designed to be reliable, cost-effective and highly integrated. It is specially designed for bidirectional level shifting and can provide a reliable solution for various applications.

In conclusion, the ISL3179EIBZ is a high speed, single channel, bi-directional level shifter which is designed to move signal between two different voltage domains. It works on the same principle as a Schottky Diode, by allowing two input signals to transition between two different voltage domains without the need for additional components. It is suitable for discrete applications, as well as automotive, industrial and residential applications, as it is highly integrated and requires minimal external components.
