1CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.Copyright © 2004, Texas Instruments IncorporatedData sheet acquired from Harris SemiconductorSCHS046ICD4049UB, CD4050BCMOS Hex Buffer/ConvertersThe CD4049UB and CD4050B devices are inverting andnon-inverting hex buffers, respectively, and feature logic-level conversion using only one supply voltage (VCC). Theinput-signal high level (VIH) can exceed the VCC supplyvoltage when these devices are used for logic-levelconversions. These devices are intended for use as CMOSto DTL/TTL converters and can drive directly two DTL/TTLloads. (VCC = 5V, VOL≤ 0.4V, and IOL≥ 3.3mA.)The CD4049UB and CD4050B are designated asreplacements for CD4009UB and CD4010B, respectively.Because the CD4049UB and CD4050B require only onepower supply, they are preferred over the CD4009UB andCD4010B and should be used in place of the CD4009UBand CD4010B in all inverter, current driver, or logic-levelconversion applications. In these applications theCD4049UB and CD4050B are pin compatible with theCD4009UB and CD4010B respectively, and can besubstituted for these devices in existing as well as in newdesigns. Terminal No. 16 is not connected internally on theCD4049UB or CD4050B, therefore, connection to thisterminal is of no consequence to circuit operation. Forapplications not requiring high sink-current or voltageconversion, the CD4069UB Hex Inverter is recommended.Features• CD4049UB Inverting• CD4050B Non-Inverting• High Sink Current for Driving 2 TTL Loads• High-To-Low Level Logic Conversion• 100% Tested for Quiescent Current at 20V• Maximum Input Current of 1µA at 18V Over Full PackageTemperature Range; 100nA at 18V and 25oC• 5V, 10V and 15V Parametric RatingsApplications• CMOS to DTL/TTL Hex Converter• CMOS Current “Sink” or “Source” Driver• CMOS High-To-Low Logic Level ConverterPinoutsOrdering InformationPART NUMBERTEMP.RANGE (oC) PACKAGECD4049UBF3A -55 to 125 16 Ld CERDIPCD4050BF3A -55 to 125 16 Ld CERDIPCD4049UBD -55 to 125 16 Ld SOICCD4049UBDR -55 to 125 16 Ld SOICCD4049UBDT -55 to 125 16 Ld SOICCD4049UBDW -55 to 125 16 Ld SOICCD4049UBDWR -55 to 125 16 Ld SOICCD4049UBE -55 to 125 16 Ld PDIPCD4049UBNSR -55 to 125 16 Ld SOPCD4049UBPW -55 to 125 16 Ld TSSOPCD4049UBPWR -55 to 125 16 Ld TSSOPCD4050BD -55 to 125 16 Ld SOICCD4050BDR -55 to 125 16 Ld SOICCD4050UBDT -55 to 125 16 Ld SOICCD4050BDW -55 to 125 16 Ld SOICCD4050BDWR -55 to 125 16 Ld SOICCD4050BE -55 to 125 16 Ld PDIPCD4050NSR -55 to 125 16 Ld SOPCD4050BPW -55 to 125 16 Ld TSSOPCD4050BPWR -55 to 125 16 Ld TSSOPNOTE: When ordering, use the entire part number.
