With the widespread adoption of electronic technology, Logic circuits are playing an increasingly important role in all areas of industrial production, such as automotive, communications, consumer and aerospace. SN74ACT8997DWR is one of these dedicated logic circuits, introduced by Texas Instruments as a substitute for the field programmable logic device. It is a low-power, high-performance micro-programmable logic integrated circuit (PLIC).

Application Field of SN74ACT8997DWR

SN74ACT8997DWR logic circuit is mainly used in automotive, aerospace, consumer and industrial applications. In automotive applications, this PLIC can be used for vehicle digital control, monitoring, data acquisition and transmission. In aerospace applications, the digital circuit can be used for flight control, avionics system and remote aircraft monitoring. It can also be used in consumer applications such as digital imaging and digital audio.

SN74ACT8997DWR circuit can also be used in industrial applications because of its low power consumption and high performance. It can be used for digital controllers in industrial control systems, used for sensors or actuator control, process control and observer, used for motion control and safety circuit.

Working Principle of SN74ACT8997DWR

The SN74ACT8997DWR micro-programmable logic circuit consists of two parts, the core unit and the decoder unit. The core unit is composed of five subunits: the arithmetic unit, instruction register, data register, control unit and program counter. The decoder unit is responsible for decoding the instruction from the instruction register.

The SN74ACT8997DWR logic consists of four stages. The first stage is the Instruction Setup stage, in which the instruction is loaded into the instruction register. The second stage is the Instruction Fetch stage, in which the control unit fetches the instruction from the instruction register and sends it to the arithmetic unit. In the Execute Instruction stage, the arithmetic unit executes the instruction then stores the result back in the data register. The last stage is the Result Retrieval stage, in which the controller checks the state of the data register and returns the result back to the user.

Conclusion

SN74ACT8997DWR application circuit is a low power, high-performance PLIC which can be used to control the digital systems in the automotive, aerospace, consumer and industrial industrial fields. It works on the instructions which is decoded by the decoder unit, executed by the arithmetic unit, and the result is returned to the user. It is an important addition to the logic circuit family and offers many advantages over the traditional field programmable logic device.
