Product Description

The N74F258AD is a versatile component that provides a high-speed multiplexing function with the capability to drive 15 LSTTL loads. When the enable input (E\) is held high, all the outputs are forced to a high-impedance state, allowing the outputs to interface directly with bus-oriented systems. With a typical power dissipation of just 40 mW, this device is optimized for power efficiency.

The multiplexer features two select inputs (S0 and S1) which control which input data from sets A0 to A3 and B0 to B3 is routed to the outputs Y0 to Y3. The selection of input data is determined by the logic levels applied to the S0 and S1 inputs. This allows for real-time switching between the input sets, making it suitable for high-speed data processing and communication systems.

The N74F258AD's fast switching speeds and low power consumption make it an ideal choice for high-performance applications. Its 3-state outputs also enable multiple devices to be connected to a common bus without interference, a feature particularly useful in digital multiplexing and data routing applications where multiple sources of data need to be directed to a single destination.

Manufactured by NXP, a trusted name in the semiconductor industry, the N74F258AD comes in a surface-mount SOIC-16 package, which is well-suited for applications with space constraints. It is also characterized for operation from -40°C to +85°C, ensuring reliability across a wide range of environmental conditions.
