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.


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 (A0 to A3) and provide 16 mutually exclusive active LOW outputs(Y0 to Y15).

The 2-input enable inputs (E0, E1) 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.
