APPLICATIONS Memory decoding or data-routing Code conversion
DESCRIPTIONThe 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
inputs (nA0 and nA1) and providing four mutually exclusive active
LOW outputs (nY0 to nY3). Each decoder has an active LOW enable
input (nE).
When nE is HIGH, every output is forced HIGH. The enable can be
used as the data input for a 1-to-4 demultiplexer application.
QUICK REFERENCE DATAGND = 0 V; Tamb = 25°C; tr = tf ≤ 2.5 ns
NOTES: CPD is used to determine the dynamic power dissipation (PD in μW)
PD = CPD × VCC 2 × fi (CL × VCC 2 × fo) where:
fi = input frequency in MHz; CL = output load capacitance in pF;
fo = output frequency in MHz; VCC = supply voltage in V;
(CL × VCC 2 × fo) = sum of the outputs.

RECOMMENDED OPERATING CONDITIONS
NOTE: The LV is guaranteed to function down to VCC = 1.0V (input levels GND or VCC); DC characteristics are guaranteed from VCC = 1.2V to VCC = 5.5V.
ABSOLUTE MAXIMUM RATINGS1, 2In accordance with the Absolute Maximum Rating System (IEC 134).
Voltages are referenced to GND (ground = 0 V).
NOTES: 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. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
