The 74F241PC is a dual 4-bit non-inverting buffer with 3-state outputs from the 74F fast logic family. Each of the two elements handles four bits independently, and the 3-state outputs let you connect them directly to a shared bus — the outputs go high-impedance when the output-enable control is inactive. The 74F family is faster than the original 74LS series, with typical propagation delays in the nanosecond range, making it suitable for buffering address, data, or control lines in 5 V bus-oriented systems like industrial controllers, test equipment, or retrofits of legacy through-hole boards.
Output drive — what the 3 mA / 64 mA numbers mean
The rated output current is asymmetric: 3 mA sourcing (output high) and 64 mA sinking (output low). That 64 mA sink capability is the headline — it can drive multiple TTL inputs, LEDs, or relay coils on the low side, but the source side is much weaker. If your load needs more than 3 mA pulled high, you will need an external pull-up or a different buffer. The 64 mA sink also means the part can absorb significant bus capacitance without ringing, but check the total package dissipation if you run all eight outputs sinking near the limit simultaneously.
Package and mounting — through-hole only
It is a legacy footprint, not for new surface-mount designs. If your board is all SMD, you will need a different package variant (e.g., SOIC-20) or an adapter socket. The through-hole form factor is still common in breadboard prototyping, educational kits, and repair of older equipment where the original 74F241 or equivalent is socketed.
Temperature range — commercial grade only
Do not plan on using it in an unheated enclosure, engine bay, or outdoor telecom cabinet — for those you would need the industrial or military temperature variant (e.g., 74F241 with a different suffix). Inside a temperature-controlled lab, office, or production floor it is fine.
Lifecycle and sourcing reality
For new designs, consider the surface-mount equivalent (74F241SC or 74F241SJ) if your board can accept it.
