Overview
The MC14043BDG is a CMOS MSI (Medium Scale Integration) quad R-S latch produced by onsemi. This device is constructed with MOS P-Channel and N-Channel enhancement mode devices in a single monolithic structure. Each latch has independent set and reset inputs, and the Q outputs are gated through three-state buffers with a common enable input. This allows the outputs to be enabled or disabled based on the state of the enable input.
