FOR DESCRIPTION OF B SERIES CMOS
DEVICES"
DESCRIPTION
The HCF4050B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available 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
).
The input high level signal (V
IH
) can exceed the
V
DD
supply voltage when these devices are 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 (V
DD
=5V,
V
OL
0.4V and I
OL
3.2mA.
