The SN74ACT1071D is an integrated circuit belonging to the Specialty Logic family of logic devices. It is a high-performance, advanced logic system that provides a cost-effective, high-speed solution for applications such as system timing, control, and data integration. The SN74ACT1071D is particularly well-suited for applications requiring low-voltage logic levels and low power dissipation.

Applications

The SN74ACT1071D can be used in a variety of applications. These include clock and data synchronization, data multiplexing and demultiplexing, address decoding, random or sequential data input or output, data buses, parallel-input serial-output shift register chain and programmable divide-by-N counters. It can also be used as a direct memory access (DMA) controller.

The SN74ACT1071D is typically used in telecommunications, test and measurement, medical equipment, automotive electronics, security systems, controllers for process control and for military applications.

Working Principle

The SN74ACT1071D operates on the principle of latching and controlling. It is designed to provide rapid switching of logic levels and to serve as an intermediary between two separate and distinct systems.

The SN74ACT1071D consists of two identical sections, each with separate latches and outputs. Each section has two latch control inputs and an enable input to serve as a master latch control. Each latch consists of two data inputs and two outputs capable of handling either positive or negative logic. The two output latches are both independently controllable.

The two data inputs denote two logic states. A logic ‘1’ logic level that is present on one data input will latch the output representing a logic ‘0’ on the other output. The same logic ‘1’ logic level will be present on the other output. Both latches have an internal tri-state feature that is activated when either the enable input (called chip enable) is not used, or is taken to a logic ‘1’ state. This allows an external device to connect either data output of the IC to the bus.

The SN74ACT1071D is capable of accepting different logic levels for its Enable input depending on the logic operating voltage used. When the logic operating is 5V, the Enable input will accept a logic ‘1’ level of 2.0V. With a logic operating voltage of 3V, the Enable input will accept a logic ‘1’ level of 0.8V.

Conclusion

The SN74ACT1071D is an advanced logic solution suitable for a variety of applications. It is capable of rapid switching of logic levels and is designed for low-voltage, low powered applications. Its ability to accept different logic levels for its enable input depending on the logic operating voltage makes it well-suited for applications requiring small power consumption. The SN74ACT1071D is a robust speciality logic system that provides a cost-effective, high-speed solution for customers.
