Quad 2-Input OR Buffered B Series Gate
Quad 2-Input AND Buffered B Series Gate
General Description
The CD4071BC and CD4081BC quad gates are monolithic
complementary MOS (CMOS) integrated circuits con-
structed with N- and P-channel enhancement mode tran-
sistors. They have equal source and sink current
capabilities and conform to standard B series output drive.
The devices also have buffered outputs which improve
transfer characteristics by providing very high gain.
All inputs protected against static discharge with diodes to
V
DD
and V
SS
.

Recommended Operating
Conditions
Note 1: "Absolute Maximum Ratings" are those values beyond which the
safety of the device cannot be guaranteed. Except for "Operating Tempera-
ture Range" they are not meant to imply that the devices should be oper-
ated at these limits. The table of "Electrical Characteristics" provides
conditions for actual device operation.
Note 2: All voltages measured with respect to V
SS
unless otherwise speci-
fied.
