What this 74F buffer does
Packaged in a 20-pin SOIC (0.295" body width), it is intended for 5 V bus driving and signal buffering in commercial-temperature equipment (0°C to 70°C).
Output drive and bus isolation
The 64 mA sink capability is notably high for a 74F buffer — enough to drive multiple TTL loads or a terminated backplane. The 3-state outputs let multiple buffers share a data bus without contention, controlled by the output-enable pins. The non-inverting path means the output follows the input polarity, simplifying board-level logic.
