DESCRIPTION
The HCF4043B is a monolithic integrated circuit
fabricated
in
Metal
Oxide
Semiconductor
technology available in DIP and SOP packages.
The HCF4043B is a quad cross-coupled 3-state
CMOS NOR latch.
Each latch has a separate Q output and individual
SET and RESET input. The Q outputs are
controlled by a common ENABLE input. A logic "1"
or "high" on the ENABLE inputs connects the latch
states to the Q outputs. A logic "0" or "low" 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 outputs.
