Description
●CD4555BMS and CD4556BMS are dual one-of-four decod ers/demultiplexers. Each decoder has two select inputs (A and B), an Enable input (E), and four mutually exclusive out puts. 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 A and B. The CD4555BMS and CD4556BMS are similar to types MC14555 and MC14556, respectively.
