Texas Instruments SN74LS251D

SN74LS251D Overview
The mounting type for this particular component is surface mount, meaning it is designed to be mounted directly onto a circuit board. Its series is 74LS, which indicates its specific type within the 74 family of integrated circuits. The JESD-609 code for this component is e4, which is a standard code used to classify the level of moisture sensitivity during the manufacturing process. This component is now considered obsolete, meaning it is no longer being produced. It has 16 terminations, or connection points, and the terminal finish is nickel palladium gold. The technology used in this component is TTL, which stands for transistor-transistor logic. It has a dual terminal position, meaning there are two sets of terminals on opposite sides of the component. The reflow temperature-max is not specified, so the manufacturer does not provide a maximum temperature for the component during the reflow process. Lastly, this component is non-RoHS compliant, which means it does not meet the regulations for restricting the use of certain hazardous substances in electronic products.
