Product Overview: CD4049UBNSRG4 - Texas Instruments

The CD4049UBNSRG4 is a versatile hex inverting buffer/converter from the renowned semiconductor manufacturer Texas Instruments. This integrated circuit (IC) is part of the 4000 series CMOS logic family, which is well-known for its high noise immunity and low power consumption. The CD4049UBNSRG4 is designed to facilitate interfacing between different voltage levels that often occur between logic families in digital systems.

This IC features six inverting buffers with high voltage inputs. It is specifically tailored for use as CMOS to DTL/TTL converters and can also serve as current drivers with up to 15mA of sink current for each buffer. This makes the CD4049UBNSRG4 an ideal choice for driving lamps, relays, or printer hammers directly from CMOS logic without the need for interface or driver circuits.

The CD4049UBNSRG4 comes in a standard 16-pin plastic small-outline package (NSOP), which is suitable for surface mount technology (SMT). This package type is designed for optimal space-saving on printed circuit boards (PCBs), making it a great fit for compact electronic applications.

Key features of the CD4049UBNSRG4 include:

• Hex inverter logic configuration
• Wide operating voltage range of 3V to 18V
• High sink current capability (15mA per buffer)
• Standardized, symmetrical output characteristics
• Medium-speed operation: t_PHL, t_PLH = 30ns (typ.) at V_DD = 10V
• High noise immunity characteristic of CMOS devices
• Low power consumption: 10nA (typ.) at V_DD = 18V
• 100% tested for quiescent current at 20V
• 5V, 10V, and 15V parametric ratings
• Maximum input current of 1µA at 18V (full package-temperature range)
• Significant power reduction compared to LSTTL logic ICs

The CD4049UBNSRG4 is not only robust in terms of its electrical specifications but also environmentally conscious. It complies with RoHS (Restriction of Hazardous Substances) standards, ensuring that it contains no harmful substances such as lead, mercury, or cadmium.

Whether you are designing consumer electronics, industrial control systems, or complex computing machinery, the CD4049UBNSRG4 offers a reliable and efficient solution for your digital logic level conversion needs.
