Logic translators and level shifters are used to enable communication between digital interfaces dependent on supply voltage. The 74ALVC164245DLG4 is a logic translators and level shifters whose application field and working principle can be described using state diagrams, digital logic, and electrical designs. By using these diagrams, the 74ALVC164245DLG4 can handle two modes of low voltage operation.

The 74ALVC164245DLG4 is a low voltage logic translator that enables the communication between different logic families with different supply voltages. The device has two data input ports, A and B, and two data output ports, Y and Z. In addition, the device has three control inputs, EN0, EN1, and PWREN, which enable the device to handle two modes of low voltage operation. The device also has an active low reset output.

The state diagrams allow us to understand how the device operates. The state diagram shows the different states that the device can be in and the conditions required to change from one state to another. State 0 is the default state, in which all data input pins, EN0 and EN1, are inactive and the active low reset output is high. In this state, the device is disabled. State 1 is achieved when EN1 is driven active and EN0 is inactive, and the device is enabled. State 2 is achieved when EN0 and EN1 are both driven active, and the device is enabled.

Digital logic is the language used to express the behavior of the device in terms of the state diagrams. In this language, logic equations are used to represent the behavior of the device. In the case of the 74ALVC164245DLG4, these equations describe how the device accepts data inputs, translates them into the appropriate outputs, and drives the active low reset output.

The electrical design of the 74ALVC164245DLG4 allows us to understand the electrical characteristics of the device. By looking at the electrical design, we can see that the device is powered by two separate power supplies, VCC1 and VCC2. We can also see that the EN0 and EN1 input pins determine the operation of the device, and the PWREN pin controls whether the device is enabled or disabled. Finally, we can see that the active low reset output is driven low when the device is enabled and goes high when the device is disabled.

In summary, the 74ALVC164245DLG4 is a logic translator and level shifter capable of handling two modes of low voltage operation. It is powered by two separate power supplies, has three control inputs, and an active low reset output. The state diagrams, logic equations and electrical design of the device allow us to understand the behavior and characteristics of the device. These features make the 74ALVC164245DLG4 an ideal choice for applications requiring low voltage operation.
