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 a replacement for the 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 voltage conversion, the CD4069UB hex inverter is recommended. The CD4049UBMS is supplied in these 16-lead outline packages: Braze Seal DIP H4S, Frit Seal DIP H1E, Ceramic Flatpack H3X.
