What are the key features of CD4511BPW?

  • Wide 3 V to 18 V supply range in the CD4000 CMOS family enables use in battery-powered, 5 V, and 12 V display systems without voltage regulation
  • Integrated BCD input latch holds digit data stable during bus transitions, eliminating an external 4-bit register for static 7-segment displays
  • Blanking and lamp-test inputs provide display brightness control and full-segment diagnostics from a single IC in a compact 16-pin TSSOP

What is CD4511BPW used for?

CD4511BPW is used in battery-powered numeric instruments, digital clocks, and industrial panel meters where BCD data from a microcontroller or counter must drive a common-anode 7-segment LED display across a wide supply range. Its wide 3 V to 18 V compatibility makes it ideal for battery-backed systems and legacy 12 V industrial equipment. The TSSOP package suits high-density SMT board layouts.

Frequently Asked Questions

What supply voltage range does CD4511BPW support, and how does this benefit battery-powered designs?

CD4511BPW operates across a 3 V to 18 V supply range as part of the CD4000 CMOS logic family, allowing it to be powered directly from lithium-ion battery packs around 3.7 V, standard 5 V logic rails, or 12 V industrial supplies without a separate regulator, reducing BOM cost and quiescent current in battery-powered numeric display instruments.

What output sink current does CD4511BPW provide per segment, and what does this mean for LED brightness?

CD4511BPW provides a maximum output sink current of 1.5 mA per segment, which is lower than HC-family counterparts at 5.2 mA. This makes it suitable for low-current LED segments or displays with external current-limiting resistors chosen for the target brightness, but external transistor drivers are recommended if segment current requirements exceed 1.5 mA in high-brightness applications.

How does the internal latch of CD4511BPW simplify 4-digit counter display circuits?

The internal BCD latch of CD4511BPW stores the 4-bit BCD input and holds the 7-segment outputs stable even when the input data changes, preventing partial-decode glitches from flickering on the display during data bus updates. This eliminates the need for a separate 4-bit transparent latch chip per digit, reducing component count and PCB area in multi-digit counter displays.

How do the blanking and lamp-test inputs of CD4511BPW support production testing on an assembly line?

The lamp-test input forces all 7 segment outputs of CD4511BPW high simultaneously, lighting every LED segment to verify no open-circuit faults in the display module during functional testing. The blanking input turns off all outputs for automated boundary-scan tests or for leading-zero suppression in displayed numbers, both achieved with a single GPIO toggled by the test controller.
