Quad R–S Latches
The MC14043B and MC14044B quad R–S latches are constructed with
MOS P–channel and N–channel enhancement mode devices in a single
monolithic structure. Each latch has an independent Q output and set and
reset inputs. The Q outputs are gated through three–state buffers having a
common enable input. The outputs are enabled with a logical “1” or high on
the enable input; a logical “0” or low disconnects the latch from the Q
outputs, resulting in an open circuit at the Q outputs.
