Compact datasheet for the SN7404N, the widely used TTL hex inverter, in a plastic DIP package indicated by the N suffix. Under 6 KB, the PDF probably contains the pin diagram and essential ratings rather than extensive characterization. Technicians reach for it when verifying that each of the six inverters outputs the opposite of its input, or when locating VCC and ground for a supply check. Open it in any PDF viewer and compare the full marking on the chip before swapping in a replacement.
