Frequently Asked Questions
What is the CD4049UBNSRG4 used for?
The CD4049UBNSRG4 serves as a CMOS hex inverting buffer and logic level converter, providing six independent inverting buffer stages. It is primarily used for level translation between logic families operating at different supply voltages, signal inversion in digital control circuits, and as an output buffer for driving moderate capacitive loads in embedded and industrial electronics designs.
Can the CD4049UBNSRG4 translate between different logic voltage levels?
Yes, the CD4049UBNSRG4 is specifically described as a buffer/converter and can accept input signals from CMOS logic operating at a different supply voltage than its output supply. For example, it can be powered at 5V while accepting 3V CMOS inputs, or powered at 12V while accepting 5V TTL inputs, making it useful for interfacing between logic systems at different voltage levels.
How many buffer channels does the CD4049UBNSRG4 contain?
The CD4049UBNSRG4 contains six independent single-input inverting buffer channels, all housed in a 16-pin SOIC package. Each channel operates independently with no internal connections between stages, allowing up to six separate signals to be inverted and buffered simultaneously using a single device.
Is the CD4049UBNSRG4 RoHS compliant?
Yes, the CD4049UBNSRG4 carries a JESD-609 'e4' rating, confirming it is lead-free and RoHS compliant. The 'G4' suffix in the part number also indicates Texas Instruments' green packaging designation, meaning the device meets both lead-free and halogen-free environmental standards for use in commercially regulated markets worldwide.
