Logic - Translators, Level Shifters are comprised of components to change signals from one logic family to another or from one voltage or current level to another. They are found in embedded systems, data and communication networks, microprocessors and in analog and digital circuit design.

SN74AUP1T97DCKRE4

The SN74AUP1T97DCKRE4 is an integrated circuit that functions as a universal bus bridge logic translator. It’s a 20-pin device, with four I/Os, allowing it to serve as a bridge between logic families that use the same voltage level.

Application Field

The SN74AUP1T97DCKRE4 is particularly useful when a system is using more than one logic family (e.g., be BCD, TTL, CMOS). For example, a vehicle\'s computer systems may need interaction between different logic families for navigation, communication, and other functionalities. In this context, the SN74AUP1T97DCKRE4 can be used to bridge the logic gap between logic families and allow communication between different systems.

The SN74AUP1T97DCKRE4 can also be used in circuit design. For example, in analog-to-digital converters and digital-to-analog converters, the SN74AUP1T97DCKRE4 can be used to provide the interface between the two different forms of data. The device can also be used to interface different voltage levels, such as a low-voltage CMOS microcontroller to a high-voltage logic family.

Working Principle

The SN74AUP1T97DCKRE4 is an active bus bridge logic translator that monitors the bus lines and translates the signals between logic families. It has two logic inputs (A and B) and two logic outputs (Y and Z). It also has two enable inputs, which enable the four-input function of the chip.

When the enable pins are low, the two input signals (A and B) are passed through, unconditionally, as output signals (Y and Z). When the enable pins are high, the two input signals are compared and one of two logic outputs is generated depending upon the input logic state.

The SN74AUP1T97DCKRE4 translates between two different logic families, operating with two different voltage levels. It is designed to operate at a low voltage (2.7V-5.5V) and can withstand a voltage up to 7.5V. It also offers wide temperature range up to -40 degrees Celsius to +85 degrees Celsius.

Examples

One application example of the SN74AUP1T97DCKRE4 is in a digital camera. The camera may have a photosensor (the BCD family) and a processing unit (the TTL family). When the photosensor feeds data to the processing unit, the SN74AUP1T97DCKRE4 can easily bridge the logic gap between the BCD and TTL logic families, while the device can provide the means of level shifting from a lower voltage to a higher voltage.

Another example is in analog-to-digital converters, where the SN74AUP1T97DCKRE4 can interface the two different kinds of data (analog and digital). The SN74AUP1T97DCKRE4 is used to switch the voltage between the two domains, making it possible to perform the conversion.
