DESCRIPTION
The 74LV139 is a low-voltage Si-gate CMOS device that is pin and
function compatible with 74HC/HCT139.
The 74LV139 is a dual 2-to-4 line decoder/demultiplexer. This device
has two independent decoders, each accepting two binary weighted

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.
