/ordering information These TTL hex Buffers
drivers feature high-voltage open-collector outputs for interfacing with high-level Circuits
(such as MOS) or for driving high-current loads (such as lamps or relays) and also are characterized for use as Buffers
for driving TTL inputs. The SN5407
have minimum breakdown voltages of 30 V, and the SN5417
have minimum breakdown voltages of 15 V. The maximum sink current is 30 mA for the SN5407
and 40 mA for the SN7407
and SN7417. These devices perform the Boolean function Y = A in positive logic.
