Each latch has a separate Q output and individual SET and RESET inputs. The Q outputs are con- trolled by a common ENABLE input. A logic “1” or high on the ENABLE input 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, results in an open circuit feature allows common busing of the outputs. The CD4043BMS and CD4044BMS are supplied in these 16- lead outline packages: Braze Seal DIP *H4T †H4T Frit Seal DIP *H1C †HIE Ceramic Flatpack *H3X †H6W *CD4043B Only †CD4044B Only File Number 3311 December 1992 |
