7407                         HEX BUFFER                        POSITIVE LOGIC    

                                                            

 

with open-collector High Voltage outputs

The 7407 IC package contains six independent positive logic non-inverting buffers. Pins 14 and 7 provide power for all six logic gates.

 

Non-Inverting buffers perform no logic manipulation. If the input is HIGH then the output is HIGH and if the input is LOW then the output is LOW. Although no logical change occurs, the 7407 can change a normal TTL signal into a high-voltage (30 VOLT) at 30mA signal. This allows a TTL device to interface with HIGH-LEVEL devices. The figure on the left is a schematic representation of the internal structure of one of the gates inside of the 7407 IC.
