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.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
