74ACT258SC

Logic - Signal Switches, Multiplexers, Decoders

74ACT258SC is a quadruple, two-channel multiplexer with separate storage latch. It has a storage latch that allows data to be stored enabling data transfer between two different busses. It is useful in applications including interconnection circuits, bus interface buffers, bus drivers, multiplexers, demultiplexers, line decoders and other circuits that require operational simplicity.

Application Field

The 74ACT258SC multiplexer has several possible applications, including but not limited to:

• Interconnection circuits,
• Bus interface buffers,
• Bus drivers
• Multiplexers
• Demultiplexers
• Line decoders
• Data selectors/ multiplexers

The 74ACT258SC typically is used in computer systems that require fast memory access, high speed, and low power consumption. The chip can also be used in systems that require a large number of data buses and/or large amounts of memory. In addition, the 74ACT258SC can be used in computers that require streamlined data routing and/or multiple memory ports.

The 74ACT258SC is also used as an efficient and economical data routing solution in application areas such as telecommunication systems, industrial control systems, medical systems, and other areas where efficient routing of data is critical.

Working Principle

At the heart of the 74ACT258SC design is a multiplexer. A multiplexer is an electronic circuit that switches electrical signals through its gates with low latency. The 74ACT258SC contains four gates. Each gate is capable of taking four distinct inputs and discretely routing them to two outputs. The two outputs are independent of each other and can be configured with different output signals.

The 74ACT258SC utilizes single edge triggered registers. When the input of the register is toggled, the output will remain stable for the duration of the clock pulse. This allows a level of logic and control to be maintained during high-speed data transfers. With multiple registers, the 74ACT258SC is capable of performing several operations simultaneously.

The 74ACT258SC also contains two separate strobe (S) inputs. Each S input is responsible for controlling one of the registers. When S is high, the register is enabled and when S is low, the register is disabled. This feature allows data to be efficiently stored and transmitted without the risk of contention.

In addition, the 74ACT258SC has an enable (EN) feature. This feature controls the selection of the data output. When EN is high, the data is routed to the output and when EN is low, the data is routed to the storage registers.

The 74ACT258SC is a cost effective, low power, and robust multiplexer that is useful in a variety of applications. With its versatile logic and data routing capabilities, the 74ACT258SC is an ideal solution for a variety of data routing tasks.
