Frequently Asked Questions (FAQ)
What does the 7407 IC do? It is a Buffer / Driver logic gate IC. The 7407 IC datasheet shows a hex buffer/driver with open-collector outputs. This 7407 datasheet includes pin diagram, specifications, and complete IC details. The 7407 integrated circuit buffer amplifies current without changing signal logic. Check the 7407 IC pin diagram and datasheet for driving heavy loads and interface applications.
What voltage does the 7407/74LS07 operate at? Standard TTL at 5V (range 4.75 V – 5.25 V). It does not work directly at 3.3V — use the 74HCT variant instead.
Where can I find the 7407/74LS07 datasheet? At the Texas Instruments official page. Also available by searching "7407/74LS07 datasheet PDF".
What is the difference between 7407 and CMOS variants? The 7407 (TTL-LS) runs only at 5V. The 74HC variants work from 2V to 6V with lower power consumption but lower output current.
Can I simulate the 7407 in Proteus or Multisim? Yes. Both simulators include the complete 74xx family. Search for "7407/74LS07" in the component library.
What is the pin diagram of the 7407? The 7407/74LS07 has 14 pins in DIP package: Pin 7 = GND, Pin 14 = VCC. The remaining pins are inputs and outputs for each gate. See the datasheet for the complete pinout diagram.
