Which IC can I use to control 7-segment display? I want to make simple projects like a reaction timer but I don't have an Arduino or some other microcontroller available. What ICs can I use instead?

  • \$\begingroup\$ There are thousands of ICs that can drive (or control) a 7 segment display but this is too many to list. \$\endgroup\$ – Andy aka Jun 5 '14 at 12:56

  • \$\begingroup\$ There's also the CD4511, that can be used to drive common-cathode displays. The 74LS'47 and 74LS'247 are used to control common-anode displays. That's an important distinction by the way: you need to know whether you have a CA or CC display. If you didn't order them yet, you need to pair them with the right driver. \$\endgroup\$ – Ricardo Jun 5 '14 at 13:01

  • \$\begingroup\$ This article seems to be a good one to start with: The 7-segment Display. It talks about common-cathode and common-anode configuration and how to drive the display with CD4511. \$\endgroup\$ – Ricardo Jun 5 '14 at 13:06

Assuming you are talking about LED 7 segment displays (as opposed to LCDs), you could use the '47 or '247 devices from the 7400 logic family, e.g. 7447.

In addition to @fmunkert

If you're talking about 7-segment LCD, you could use CD4054/4055/4056 CMOS chips.
