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 pr oviding very high gain.
All inpu ts protected a gainst st atic discha rge with dio des to
VDD and VSS.
Features
Low power TTL compatibility:
Fan out of 2 driving 74L or 1 driving 74LS
5V–10V–15V parametric ratings
Symmetrical output characteristics
Maximum input leakage 1 µA at 15V over full
temperature range
Ordering Code:
Devices are also av ailable in Tape and Re el. Speci fy by append ing the suffix let t er X to th e ordering c ode.

Conditions
Note 1: Absolute Maximum Ratings are tho se values be yond which t he
safety of the device cannot be guaranteed. Except for Operat ing Tempera-
ture Range they are not mea nt 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 VSS unless otherwise speci-
fied.
