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.
The CD4555BMS and CD4556BMS are supplied in these
16-lead outline packages:
