CD4049UBT

CD4049UBT Data Sheet July 1999 File Number 4622.1 CMOS Hex Buffer/Converter Intersil’s Satellite Applications FlowTM (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 (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 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. Features QML Class T, Per MIL-PRF-38535 ...
