What are the key features of CD4050BNSR?
- 6 independent non-inverting buffer channels enabling parallel signal distribution in a single compact package
- 3 V to 15 V wide supply range allowing logic-level translation between 5 V CMOS and 3.3 V systems
- CMOS technology delivering near-zero quiescent current for power-sensitive battery-operated designs
- High noise immunity meeting standard CD4000 series specifications for robust operation in industrial environments
What is CD4050BNSR used for?
The CD4050BNSR is widely used for logic-level translation between 5 V CMOS and lower-voltage 3.3 V or 2.5 V digital systems, protecting sensitive microcontroller inputs from overvoltage. It serves as a signal buffer and line driver in communication interfaces, display drivers, and industrial I/O expansion boards where multiple channels must be driven simultaneously. Its wide 3 V to 15 V operating range also makes it valuable in automotive and legacy industrial control systems requiring interface compatibility across different supply domains.

Frequently Asked Questions
How many buffer channels does the CD4050BNSR provide and what logic families can it interface?
The CD4050BNSR integrates 6 non-inverting buffer channels in a single package, enabling it to translate between 5 V CMOS and 3.3 V or lower-voltage logic families. Each channel can sink and source current sufficient to drive TTL inputs directly. Its 3 V to 15 V supply range makes it compatible with a broad range of CMOS and TTL voltage domains in the same design.
What supply voltage does the CD4050BNSR support and how does that benefit level-shifting applications?
The CD4050BNSR operates from 3 V to 15 V VDD, allowing it to bridge logic levels between 5 V legacy CMOS systems and modern 3.3 V microcontrollers without additional translation ICs. Running the device from a 5 V rail while accepting 3.3 V inputs provides a cost-effective single-component solution for 6 signal lines simultaneously, reducing BOM count in mixed-voltage designs.
In which embedded system application scenarios is CD4050BNSR the most practical buffer choice compared to discrete transistors?
The CD4050BNSR is the most practical choice when 6 parallel signal lines all need buffering at the same time, such as driving a 6-bit parallel display interface or buffering 6 address lines in an EEPROM expansion circuit from a 5 V bus. Using 6 discrete transistors would require 12 or more passive components, while the CD4050BNSR replaces that with a single 16-pin Small Outline package consuming less than 1 mA quiescent current.
Is CD4050BNSR suitable for replacing CD4050B in the same PCB footprint?
Yes, the CD4050BNSR is a Small Outline (SOIC) package variant of the CD4050B family, offering the same 6-channel non-inverting buffer function in the standard 16-pin SOIC footprint approximately 10 mm × 4 mm. Designers upgrading from DIP to surface-mount layouts can adopt CD4050BNSR directly since the electrical specifications — including 3 V to 15 V supply range and CMOS noise margins — are identical to the through-hole version.
