What is CD4511BNSRG4 used for?
The CD4511BNSRG4 is commonly used to drive single-digit common-cathode seven-segment LED displays in digital clocks, counters, panel meters, and frequency displays where a BCD input from a microcontroller or counter IC must be decoded and latched before display. It is also applied in industrial score boards, temperature indicators, and consumer appliance displays where the integrated latch function simplifies the interface to multiplexed digit drive circuits.

Frequently Asked Questions
What display type does the CD4511BNSRG4 directly drive and what is the per-segment output current?
The CD4511BNSRG4 is designed to directly drive common-cathode seven-segment LED displays, providing up to 1.5 mA (I_ol = 0.0015 A) sink current per segment. For standard low-current LED displays with 2 mA or less forward current, this eliminates the need for external current-limiting transistors in low-brightness digit display applications.
How does the built-in latch in the CD4511BNSRG4 simplify multiplexed display designs?
The CD4511BNSRG4 includes a 4-bit input latch controlled by a dedicated latch enable pin, allowing the BCD input to be updated and then frozen while the segment outputs hold their decoded state. In multiplexed multi-digit display systems, this latch eliminates glitches during digit scanning and reduces the microcontroller's real-time update burden, particularly at 50 pF load capacitance per segment pin.
Can the CD4511BNSRG4 replace the 74LS47 or 74HC4511 decoder/drivers in a new 5 V display design?
The CD4511BNSRG4 is functionally equivalent to the 74HC4511 and is pin-compatible in CMOS-dominant 5 V systems. It differs from the 74LS47, which drives common-anode displays with active-low outputs; the CD4511BNSRG4 drives common-cathode displays with active-high outputs. Always verify display polarity before substitution to avoid incorrect segment illumination patterns.
What is the expected supply availability for the CD4511BNSRG4 in a 10-year production program?
The CD4511BNSRG4 carries a YTEOL (Years To End Of Life) rating of 15 years, meaning Texas Instruments plans to continue producing this device through at least the late 2030s. Combined with its RoHS-compliant Pb-free packaging and standard 4000-series CMOS sourcing from multiple suppliers, it offers strong long-term supply security for industrial panel meter and consumer appliance programs with decade-long production runs.
