CD4050BMS

CMOS Hex Buffer/Converter

DATASHEET

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 appli-

cations 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 appli-

cations not requiring high sink current or voltage conversion,

the CD4069UB Hex Inverter is recommended.

The CD4050BMS is supplied in these 16 lead outline pack-

ages:
