Working Principles

The HEF4043BT,652 is a quad R/S latch that stores data based on the state of its inputs. Each latch has two inputs: Reset (R) and Set (S). When the R input is activated, the corresponding latch output becomes low, while activating the S input sets the output to high. The three-state outputs allow multiple devices to share a common bus without causing signal conflicts.
