SN74LS51NS is listed in the Gates And Inverters - Multi-Function, Configurable range at ChipApex. The manufacturer field lists Texas Instruments. Its product description is AND-OR-INVERT GATE 14SO. Review the specifications below when checking this part for your BOM.
The SN74LS51NS is a dual AND-OR-Invert (AOI) gate integrated circuit manufactured by Texas Instruments. It belongs to the 74LS series of low-power Schottky logic devices. The component features two independent AOI functions, each accepting four inputs to produce a single inverted output. It is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package with a width of 0.3 inches. The device operates within a standard voltage range and supports an industrial temperature span from -40°C to 85°C.
Verify the specific suffix against the manufacturer's current datasheet to confirm pinout compatibility and electrical characteristics. Ensure the SOIC package dimensions match the target PCB footprint. Confirm RoHS compliance status if required by assembly specifications.
Select this component when dual AOI functionality is required within a low-power Schottky logic family. Consider the 14-pin SOIC package constraints for board space. Verify that the input drive requirements align with the source logic family outputs.
This part is a member of the Texas Instruments 74LS logic family, designed for general-purpose digital applications. It provides a compact solution for implementing complex Boolean expressions using standard AOI gates. The LS series offers a balance between power consumption and switching speed suitable for many embedded systems.
Check for direct equivalents such as the SN74LS51N or SN74LS51DR. Verify functional equivalence and package compatibility before substitution.
