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.
