Key Features
- BCD-to-7-segment decoder with integrated latch enabling direct LED display driving at up to 25 mA per segment output without external current-limiting transistors
- Wide supply voltage range of 3 V to 18 V with CMOS logic compatibility, allowing operation from battery-powered and standard 5 V or 12 V logic systems
- Built-in blanking, latch enable, and lamp test inputs providing flexible display control functions in a standard 16-pin DIP package for through-hole prototyping and production
Applications
The CD4511BE is widely used to drive common-cathode 7-segment LED displays in digital clocks, counters, and instrumentation panels where BCD encoded data from a microcontroller or counter IC must be displayed as decimal digits. Its wide 3 V to 18 V supply range and 25 mA output drive capability allow it to directly illuminate LED segments without external transistors, simplifying schematic design. The device is also common in educational electronics kits and prototyping boards where through-hole DIP packaging and straightforward BCD decoding logic are preferred.

Frequently Asked Questions
What supply voltage range does the CD4511BE operate over, and what output drive current can it supply to LED segments?
The CD4511BE operates from 3 V to 18 V and provides up to 25 mA per segment output, enabling it to directly drive common-cathode 7-segment LED displays without external current-boosting transistors across a wide range of system supply voltages.
What input encoding format does CD4511BE decode, and which display type is it compatible with?
The CD4511BE accepts 4-bit BCD (Binary Coded Decimal) inputs representing digits 0 through 9 and decodes them into the 7-segment patterns required for common-cathode LED displays. Invalid BCD codes 10 through 15 cause all segment outputs to go low, blanking the display.
How do the blanking and latch enable inputs on CD4511BE enhance display system flexibility?
The blanking input (BI) overrides all segment outputs to turn off the display without disturbing latch or BCD data, useful for multiplexed display scan circuits. The latch enable (LE) input freezes the decoded output independently of BCD input changes, allowing the display to hold a stable reading while new data is being loaded into an upstream counter or register running at frequencies up to several MHz.
When is CD4511BE a practical lower-cost alternative to a microcontroller GPIO-driven 7-segment display?
In systems with an existing BCD counter output — such as CD4510 or CD4516 binary-coded counters — the CD4511BE decodes and drives the 7-segment display using 0 MCU pins, freeing all 7 GPIO lines that direct-drive would consume. For displays showing a single digit counter on a fixed 5 V or 12 V rail, this saves both firmware complexity and at least 7 microcontroller I/O pins.
