Frequently Asked Questions
What is the SN74F258D and what does it do?
The SN74F258D is a quadruple 2-line to 1-line data selector/multiplexer with 3-state outputs from Texas Instruments. It contains four independent 2-to-1 multiplexer channels, each capable of selecting one of two input lines and routing it to a common output. The 3-state outputs allow the device to be connected directly to shared data buses.
What are the key electrical specifications of the SN74F258D?
The SN74F258D features a maximum output low current (I_OL) of 20mA, a load capacitance (CL) of 50pF, and operates in the F/FAST logic family for high-speed performance. It is housed in a 16-pin SOIC package (JESD-30 code R-PDSO-G16) and is lead-free (Pb-free) compliant with JESD-609 code e4.
What are typical applications for the SN74F258D?
The SN74F258D is commonly used in data bus multiplexing, microprocessor address and data routing, memory system interfaces, and FPGA expansion designs. Its 3-state outputs make it suitable for multi-device bus architectures in industrial control systems, communication equipment, and embedded computing platforms.
What is a compatible replacement or alternative for the SN74F258D?
Compatible alternatives include the 74F258 series from other manufacturers such as ON Semiconductor (MC74F258D) and Fairchild Semiconductor. The SN74LS258B or SN74S258 may also serve as functional substitutes depending on speed and power requirements. Always verify supply voltage, output drive strength, and propagation delay when substituting.
