The SN7407N is a hex buffer/driver in 14 pin DIP package. It features high voltage open collector outputs for interfacing with high level circuits (MOS), driving high current loads (such as lamps or relays). It also characterized for use as buffers for driving TTL inputs. The SN7407 has minimum breakdown voltage of 30V and maximum sink current of 40mA. This device performs boolean function Y=A in positive logic. Inputs are diode clamped to minimize transmission line effects which simplifies design.
