Driving a 7 segment Display 4511 (CB084E)

The 4511 is a 7-segment latch driver providing up to 25 mA in each output. The typical application using the 4518 as a counter is shown in the figure. Typical values for the current liumiting resistor are given in the diagram. If the store input is put to “1”, the last value is held in the display. When store input is “0”, the decoder follows the count. Cascading two blocks in this manner,. We can build a counterup to 99. The display is any type with common cathode. The typical value for the current limiting resistor is 220 Ω.
