DESCRIPTION

The M54HC154 is an high speed CMOS 4 TO 16

LINE DECODER/DEMULTIPLEXER fabricated

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.
