Motorola SN74LS48N IC BCD TO 7-Segment Decoder
If you want the best solution for driving 7-segment displays then check out the Motorola SN74LS48N IC BCD to 7-Segment Decoder. This small chip converts 4-bit binary numbers into numbers that can be read on a 7-segment display. It works great and has features like automatic zero-blanking to keep the screen clear.
Because of the built-in resistors, you can also modify the brightness of the lights without the need for additional parts. It's an excellent solution for any project requiring easy-to-read displays.
