The 74HC154 is a high speed CMOS4 TO 16-LINE DECODER/DEMULTIPLEXER fabricated in silicon gate C2MOStechnology. It has the same high speed performance ofLSTTL combined with trueCMOSlow power  onsumption.

A binary code applied to the four inputs (A to D) provides alowlevel at the selected one ofsixteen outputs excluding the other fifteen outputs, when both the strobe inputs, G1 and G2, are held low. When either strobe input is held high, the decording function is inhibited to keep all outputs high. The strobe function makes 74HC154 easy to expand the decoding lines through cascading, and simplifies the design of address decoding circuits in memory control systems.

74HC154 All inputs are equipped with protection circuits against static discharge and transient excess voltage.
