The M54/74HC155 is a high speed CMOS DUAL 2TO-4 LINE DECODER fabricated in silicon gate C2MOS technology.

dual 1-TO-4 line demultiplexers with individual strobe inputs (1G and 2G), individual data inputs (1C and 2C) and common binary address inputs (A and B). When both decoders are enabled by the strobes, the inverted output of 1C data and non-inverted output of 2C data will be brought to the select output pins of each sections. A 1-TO-8 line demultiplexer can also be easily built up by providing a data signal to both 1C and 2C inputs ; the output order from the msb is 1Y3, 1Y2, 1Y1, 1Y0, 2Y3, 2Y2,.
