CD4049UBMS
Data Sheet
December 1992
File Number 3315
CMOS Hex Buffer/Converter
Features
• High Voltage Type (20V Rating)
The CD4049UBMS is an inverting hex buffer and features
logic level conversion using only one supply (voltage (VCC).
The input signal high level (VIH) can exceed the VCC supply
voltage when this device is used for logic level conversions.
This device is intended for use as CMOS to DTL/TTL
converters and can drive directly two DTL/TTL loads. (VCC
= 5V, VOL ≤ 0.4V, and IOL ≥ 3.3mA.
• Inverting Type
• 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 Pack-
The CD4049UBMS is designated as replacement for
CD4009UB. Because the CD4049UBMS requires only one
power supply, it is preferred over the CD4009UB and
CD4010B and should be used in place of the CD4009UB in
all inverter, current driver, or logic level conversion applica-
tions. In these applications the CD4049UBMS is pin compat-
ible with the CD4009UB, and can be substituted for this
device in existing as well as in new designs. Terminal No. 16
is not connected internally on the CD4049UBMS, therefore,
connection to this terminal is of no consequence to circuit
operation. For applications not requiring high sink current or
voltage conversion, the CD4069UB Hex Inverter is recom-
mended.

Applications
• CMOS to DTL/TTL Hex Converter
• CMOS Current “Sink” or “Source” Driver
• CMOS High-to-Low Logic Level Converter
