CD4511 BCD to 7-Segment Display Driver BCD to seven segment Latch Decoder CMOS CD4511BE


The CD4511 is a BCD to 7-segment decoder. It means it takes a number in binary form as an input, then displays this number on a 7-segment display using its outputs.


A 7-segment display is a component with seven Light-Emitting Diodes (LED) arranged as shown below. By turning on different combinations of the LEDs, a number between 0 and 9 is displayed.


The CD4511B types are BCD-to-7-segment latch decoder drivers constructed with CMOS logic and n-p-n bipolar transistor output devices on a single monolithic structure
High-output-sourcing capability.up to 25 mA, Input latches for BCD Code storage, Lamp Test and Blanking capability
7-segment outputs blanked for BCD input codes > 1001
100% tested for quiescent current at 20 V, Max. input current of 1 µA at 18 V, over full package-temperature range, 100 nA at 18 V and 25°C, 5-V, 10-V, and 15-V parametric ratings


Example Applications: Driving common-cathode LED displays, Multiplexing with common-cathode LED displays, Driving incandescent displays, Driving low-voltage fluorescent displays
