The HCC4049UB/4050B (extended temperature
range) and the HCF4049UB/4050B (intermediate
temperature range) are monolithic integrated cir-
cuits available in 16-lead dual in-line plastic or ce-
ramic package and plastic micro package.
The HCC/HCF4049UB/4050B are inverting and
non-inverting hex buffers, respectively, and feature
logic-level conversion using only one supply voltage
(V
DD
). The input-signal high level (V
IH
) can exceed
the V
DD
supply voltage when these devices are used
for logic level conversions. These devices are in-
tended for use as COS/MOS to DTL/TTL converters
and can drive directly two DTL/TTL loads (V
DD
= 5V,
V
OL
0.4V, and I
OL
3.2mA).

Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions above those indicated in the operational sec-
tions of this specifi cation is not implied. Exposure to absolute maximum rating conditions for external periods may affect device
reliability.
