The CD40107BM96 is a dual 2-input NAND gate from the 4000B series, with open-drain outputs. That open-drain stage means the output can sink current but cannot source it — you pull it up externally to whatever voltage the load needs, up to the 18 V supply limit. This makes it useful for driving relays, LEDs, or interfacing to a higher-voltage bus where a standard push-pull gate would clamp the line.
That means it is still a standard catalog item through TI and its distribution network. For BOM planning, there is no imminent obsolescence risk, and the part can be dual-sourced with other 4000B-series open-drain NAND gates if a second source is needed — though the exact pinout and drive current should be verified against the datasheet.
