CD4556BMS中文资料INTERSIL数据手册PDF规格书

描述 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.
