DESCRIPTION
The
HCC4043B, HCC4044B,
(extended tempera-
ture range) and the
HCF4043B, HCF4044B
(inter-
mediate temperature range) are monolithic
integrated circuits, available in 16-lead dual in-line
plastic or ceramic package and plastic micropack-
age. The
HCC/HCF4043B
types are quad cross-
coupled 3-state COS/MOS NOR latches and the
HCC/HCF4044B
types are quad cross-coupled 3-
state COS/MOS NAND latches. Each latch has a
separate Q output and individual SET and RESET
inputs. The Q outputs are controlled by a common
ENABLE input. A logic 鈥?鈥?or 鈥漢igh鈥?on the ENABLE
input connects the latch states to the Q outputs. A
logic 鈥?鈥?or 鈥漧ow鈥?on the ENABLE input disconnects
the latch states from the Q outputs, resulting in an
open circuit condition on the Q outputs. The open
circuit feature allows common bussing of the out-
puts.
