|
The LS155 and LS156 are Dual 1-of-4 Decoder/Demultiplexers with mon Address inputs and separate gated Enable inputs. When enabled, each decoder section accepts the binary weighted Address inputs (A0, A1) and provides four mutually exclusive active LOW outputs (O0 O3). If the Enable requirements of each decoder are not met, all outputs of that decoder are HIGH.
