The interface - drivers, receivers, transceivers is an important type of electronic equipement used in communication, it is responsible for controlling electrical signal between pieces of devices. ISL3150EIUZ-T is an important device of this type, it has been widely used in many field and it has a unique working principle. In this article, we will discuss the application field and the working principle of ISL3150EIUZ-T.

ISL3150EIUZ-T is a non-latching, single-channel 3.0V to 5.5V level shifting device. It has high noise immunity, wide supply range, wide bandwidth and very low propagation delay. Therefore, it has become increasingly important in the field of communication and other inter-electronic equipment connection. It is widely used in audio, radio and video transmission system, high speed HDMI receiver and transmitter, Universal Serial Bus connection, optical communication system and other industrial and commercial equipment.

The working principle of ISL3150EIUZ-T is that it converts three different 3.0V to 5.5V logic levels between inputs and outputs. The ISL3150EIUZ-T has an active low enable (ENb) input, and two additional 3-state control inputs which determine the logic levels at the output. The ENb input enables (disables) the output, while the two control inputs define the logic levels. When both the control inputs are connected to ground (0V), the logic high output is LVCMOS level. When one of the input is connected to Vcc (3.0V to 5.5V) and the other to ground, the output level is LVCMOS at Vcc level. If both inputs are connected to Vcc, the output is LVTTL level.

The ISL3150EIUZ-T has an internal logic cell which guarantees glitch-free, propagation delay matched outputs when it switches between logic levels. The device also uses a hysteresis circuit to minimize the possibility of output glitches when the voltage at the control inputs changes quickly. The output switch timing is function of the supply voltage and the load on the output stage. It is important that the operation of the device is stable over the temperature range of -40 to +85 C.

In summary, ISL3150EIUZ-T belongs to interface-drivers, receivers, transceivers, which is widely used in many fields. Its working principle is to convert 3 different 3.0V to 5.5V logic levels between inputs and outputs. Its active low enable input and two additional 3-state control inputs can determine the logical levels of the output. The device is characterized by its high noise immunity and wide supply range, and it has the capability to provide glitch-free propagation delay matched outputs over a wide range of temperatures.
