CMOS Hex Buffer/Converter

The CD4050BMS is an non-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 CD4050BMS is designated as replacement for CD4010B. Because the CD4050BMS requires only one power supply, it is preferred over the CD4010B and should be used in place of the CD4010B in all inverter, current driver, or logic level conversion applications. In these applications the CD4050BMS is pin compatible with the CD4010B, and can be substituted for this device in existing as well as in new designs. Terminal No. 16 is not connected internally on the CD4050BMS, 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 ecommended.

The CD4050BMS is supplied in these 16 lead outline pack ages:

Braze Seal DIP H4T

Frit Seal DIP H1E

Ceramic Flatpack H3X
