Overview

Description

The CD4555BMS and CD4556BMS are dual one-of-four decoders/demultiplexers. Each decoder has two select inputs, an Enable input, and four mutually exclusive outputs. On the CD4555BMS the outputs are high on select; on the CD4556BMS the outputs are low on select. When the Enable input is high, the outputs of the CD4555BMS remain low and the outputs of the CD4556BMS remain high regardless of the state of the select inputs. The CD4555BMS and CD4556BMS are similar to types MC14555 and MC14556, respectively. The CD4555BMS and CD4556BMS are supplied in these 16-lead outline packages: Braze Seal DIP H46 (CD4555BMS) and H4T (CD4556BMS), Frit Seal DIP H1E, Ceramic Flatpack H6W.
