CD4049UBT
CMOS Hex Buffer/Converter
Intersil's Satellite Applications Flow
TM
(SAF) devices are fully
tested and guaranteed to 100kRAD total dose. These QML
Class T devices are processed to a standard flow intended
to meet the cost and shorter lead-time needs of large
volume satellite manufacturers, while maintaining a high
level of reliability.
The CD4049UBT is an Inverting Hex Buffer and features
logic level conversion using only one supply (voltage (V
CC
).
The input signal high level (V
IH
) can exceed the V
CC
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. (V
CC
=
5V, V
OL
0.4V, and I
OL
3.3mA.
The CD4049UBT is the designated replacement for the
CD4009UB. Because the CD4049UBT 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 CD4049UBT 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 CD4049UBT,
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
recommended.
