Product Description:
The 74F257ASJX is a versatile and reliable component that provides four individual 2-input multiplexers with 3-state outputs, which can be used to pass or block data signals. The 3-state outputs allow for connection to a common bus, which is controlled by the output enable (OE) input. When the OE input is high, the outputs are in a high impedance state, effectively isolating the outputs from the bus.
Each multiplexer has two data inputs (A and B), a select input, and an output. The select input determines which of the data inputs is connected to the output. This functionality is essential for applications where multiple data lines need to be controlled and selectively routed through a single channel.
Designed with high-speed switching in mind, the 74F257ASJX operates with a typical voltage of 5V and features a fast propagation delay, minimizing the transition time between signals and ensuring efficient performance in high-speed digital environments. The SOIC-16 package allows for a compact footprint on printed circuit boards, suitable for space-constrained applications.
With its robust design and ON Semiconductor's commitment to quality, the 74F257ASJX is a reliable choice for designers looking to implement multiplexing functionality in their digital systems.
