SN74LS51NSR is listed in the Gates And Inverters - Multi-Function, Configurable range at ChipApex. The manufacturer field lists Texas Instruments. Its product description is IC AND-OR-INVERT GATE 14SO. Review the specifications below when checking this part for your BOM.
The SN74LS51NSR is a dual 2-wide 2-input/3-input AND-OR-INVERT gate manufactured by Texas Instruments. It belongs to the 74LS logic series and operates within a supply voltage range of 4.75V to 5.25V. The device features two independent logic circuits, each providing complex combinational logic functions through its specific gate structure. Designed for surface-mount applications, it utilizes a 14-pin SOIC package. The component supports an operating temperature range from -40°C to 85°C, ensuring reliability in industrial environments.
Verify the exact suffix 'NSR' against the manufacturer's official documentation to confirm the specific tape-and-reel packaging and lead-free status. Ensure the ordering part number matches the required package type and environmental compliance specifications before finalizing procurement.
Select this component when a compact surface-mount solution for dual AND-OR-INVERT gates is required. Consider the LS series characteristics regarding speed and power consumption relative to system requirements. Verify that the 14-pin SOIC footprint aligns with the PCB layout constraints.
This device is part of the standard 74LS family of digital logic integrated circuits. It serves as a fundamental building block for creating complex logic expressions without requiring multiple discrete gates. The SN74LS51 variant specifically offers a versatile combination of AND and OR operations followed by inversion.
Direct substitutes include SN74LS51N and SN74LS51DR. Verify pinout compatibility and electrical specifications before substitution.
