SN74F258NSR by Texas Instruments

The SN74F258NSR is a high-performance, quadruple 2-line to 1-line data selector/multiplexer integrated circuit brought to you by Texas Instruments, a leader in semiconductor design and manufacturing. This versatile component is a vital part of digital systems, especially when there is a need to select between multiple data sources or route data efficiently within a circuit.

Constructed with advanced silicon-gate BiCMOS technology, the SN74F258NSR offers a robust combination of speed and low-power operation. This makes it an excellent choice for interfacing with high-speed microprocessors without compromising power efficiency. It is capable of working with a wide operating voltage range, typically from 4.5V to 5.5V, which allows it to integrate seamlessly into a variety of digital systems.

The device features a common output enable (OE) input, which simplifies the control of output states. When OE is high, all outputs are forced to a high-impedance state, allowing for the outputs to effectively disconnect from the rest of the circuit, preventing any potential back-driving of the outputs when they are not in use.

Each multiplexer in the SN74F258NSR has two input lines (A and B) and an output line (Y). The selection of the input is controlled by a common select input (S), which determines which of the inputs A or B is connected to the output Y. When the select input is low, input A is connected to the output, and when high, input B is connected. This simple yet powerful functionality makes it a versatile component for creating complex logic functions or expanding the input capability of a microprocessor or other digital logic circuits.

Available in a compact 16-pin SOP (Small Outline Package), the SN74F258NSR is designed for surface-mount technology, making it suitable for modern high-density electronic assemblies. Its small footprint ensures that it takes up minimal space on a printed circuit board, which is critical in today's space-constrained applications.

Whether you are designing data routers, signal gateways, or need a reliable way to control data flow in your digital system, the SN74F258NSR from Texas Instruments is a reliable and efficient choice that delivers performance and versatility in a compact package.
