DESCRIPTION
The 74LV154 is a low-voltage CMOS device and is pin and function
compatible with 74HC/HCT154.
The 74LV154 decoders accept four active HIGH binary address
inputs (A
0
to A
3
) and provide 16 mutually exclusive active LOW
outputs(Y
0
to Y
15
).
The 2-input enable inputs (E
0
, E
1)
can be used to strobe the
decoder to eliminate the normal decoding “glitches” on the outputs,
or it can be used for expansion of the decoder.
The enable input has two AND’ed inputs which must be LOW to
enable the outputs.
The 74LV154 can be used as a 1-to-16 demultiplexer by using one
of the enable inputs as the multiplexed data input.
When the other enable is LOW, the addressed output will follow the
state of the applied data.
