MM54C157中文资料Quad 2-Input Multiplexers数据手册TI规格书

描述 Description

General Description
These multiplexers are monolithic complementary MOS (CMOS) integrated circuits constructed with N- and P-channel enhancement transistors. They consist of four 2-input multiplexers with common select and enable inputs. When the enable input is at logical ‘‘0’’ the four outputs assume the values as selected from the inputs. When the enable input is at logical ‘‘1’’, the outputs assume logical ‘‘0’’. Select decoding is done internally resulting in a single select input only.
