7 segment display datasheet

This would be just fine if you had a high-side driver for the individual anodes of the 7-segment display, but I'm assuming that you don't. You can use the NPN transistors to sink current from the common cathode when you want to select an individual 7-segment display if you are multiplexing them.

7 SEGMENT LED DATASHEET Datasheet(PDF) - BetLux Electronics - BL-D39C-21 Datasheet, 10.0mm(0.39) Dual digit Seven Segment LED display series, BetLux Electronics - BL-Q40E-41 Datasheet, BetLux Electronics - BL-D56E-22 Datasheet CD4026 is a Johnson counter IC commonly used in digital display. It has a 5 stage Johnson decade counter with a decoder which converts the Johnson code to a 7 segment decoded output. To put it simply, it will convert the input into numeric display and can be seen on 7 segment display or with LED. It ...
Driving a 7-segment Display. Although a 7-segment display can be thought of as a single display, it is still seven individual LEDs within a single package and as such these LEDs need protection from over current. LEDs produce light only when it is forward biased with the amount of light emitted being proportional to the forward current.
