Product Description

The SN74LS258BDR2 is designed with the capability to select one of two data sources for each output based on the state of a common Select input. It features four identical units, each capable of handling two input lines (A and B) and producing one output (Y). The common Select input determines which set of inputs (A or B) is routed to the outputs. This device also includes an Enable input which, when at a low logic level, allows the selected data to pass through. When the Enable input is high, all outputs are forced to a high impedance state, effectively isolating the outputs from the inputs.

Due to its high-speed performance and low power consumption, this multiplexer is suitable for various applications, including data routing, signal gating, and the creation of function generators. Its differential outputs ensure improved noise immunity, making it a reliable choice for complex digital systems.

The SN74LS258BDR2 comes in a compact SOIC-16 package, which is ideal for space-constrained applications. It is also characterized for operation over the full military temperature range of -55°C to 125°C, ensuring reliability under extreme conditions. With its robust design and ON Semiconductor's commitment to quality, this multiplexer is a dependable component for both commercial and military applications.
