DESCRIPTION
The M54HC154 is an high speed CMOS 4 TO 16 LINE DECODER/DEMULTIPLEXER fabricated with silicon gate C2MOS technology.
A binary code applied to the four inputs (A to D) provides a low level at the selected one of sixteen 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 decoding function is inhibited to keep all outputs high. The strobe function makes it easy to expand the decoding lines through cascading, and simplifies the design of address decoding circuits in memory control systems.
All inputs are equipped with protection circuits against static discharge and transient excess voltage.
