The SN74F241N: Two elements, each handling four bits independently, with 3-state outputs for bus sharing.
Output drive rated 15 mA sourcing and 64 mA sinking.
The 20-pin DIP (0.300" body) is a through-hole package, which means it fits breadboards, prototype boards, and legacy PCB retrofits where surface-mount isn't practical.
Yes, the SN74F241N is a non-inverting buffer with 3-state outputs. The output follows the input — no logic inversion.
A close functional peer is the SN74LS645-1N, an 8-bit transceiver in the same 20-pin DIP footprint. The LS645 adds direction control (transceiver vs buffer) but shares the same 5 V supply and through-hole package. For a direct buffer replacement, the SN74F241N is the cleaner fit.
