TL F 66059312 DM9312 One of Eight Line Data Selectors MultiplexersJune1989 9312 DM9312One of Eight LineData Selectors MultiplexersGeneral DescriptionThese data selectors multiplexers contain inverter driversto supply full complementary on-chip binary decoded dataselectionThe9312is a single8-bit multiplexer with complementaryoutputs and a strobe control When the strobe is low thefunction is enabled When a high logic level is applied to thestrobe the output is forced to the logic zero state regardlessof the logic level of the data inputsFeaturesY Selects one-of-eight data sourcesY Performs parallel to serial conversionY Strobe controlled outputsY Complementary outputsConnection DiagramDual-In-Line PackageTL F 6605–1Order Number9312DMQB 9312FMQB or DM9312NSee NS Package Number J16A N16E
