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.
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
applications. In these applications the CD4049UBMS is pin
compatible 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 voltageconversion, the CD4069UB Hex Inverter is
recommended.
