DESCRIPTION
The HCF4050B i s a monoli thic integrated circuit
fabricated in Metal Oxide Semiconductor
technology ava ilabl e in DIP and SOP packages.
It is an non inverting Hex Buffer/Converter and
feature logic level conversions using only one
supply voltage (V
DD
).
PIN CONNECTION
The input high level s ignal (V
V
supply voltage when these dev ices are used

) can exceed the
IH
for logic level conversions. This device is intended
for use as CMOS to DTL/TTL converters and can
drive directly two DTL/TTL loads (V
V
≤0.4V and IOL≤3.2mA.
