DESCRIPTION
HCF4048B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
HCF4048B is an 8-input ga te having four control
inputs. Three binary control inputs K
, Kb, and K
a
provide the implementation of eight different logic
functions. These functions are OR, NOR, AND,
NAND, OR/AND, OR/NAND, AND/OR and AND/
NOR. A fourth control input K
with a 3 state output. When control input K

the output is either a logic 1 or a logic 0 depending
on the inner states. When control input K
the output is an open c i rcuit. T his feat ure enables
the user to connect this device t o a common bus
line. In addition to the eight input lines, an
EXPAND input is pro vided that permits the user to
c
increase the number of inpu ts to one HCF4048B.
For example, two HCF4048Bs can be cascaded to
provide a 16 input multifunction gate. When the
EXPAND input is no t used , it should be connected
to V
.
