74LVC139
Dual 2-to-4 line decoder/demultiplexer
Rev. 5 — 19 October 2011
Product data sheet
1. General description
The 74LVC139 is a dual 2-to-4 line decoder/demultiplexer. It has two independent
decoders, each accepting two binary weighted inputs (nA0 and nA1) and providing four
mutually exclusive outputs (nY0 to nY3) that are LOW when selected. Each decoder has
an active LOW input (nE). When nE is HIGH, every output is forced HIGH. The enable
input can be used as the data input for a 1-to-4 demultiplexer application.
2. Features and benefits
Wide supply voltage range from 1.2 V to 3.6 V
Inputs accept voltages up to 5.5 V
CMOS low power consumption
Direct interface with TTL levels
Demultiplexing capability
Two independent 2-to-4 decoders
Multifunction capability
Mutually exclusive outputs
Output drive capability 50
transmission lines at 125
C
Complies with JEDEC standard:
JESD8-7A (1.65 V to 1.95 V)
JESD8-5A (2.3 V to 2.7 V)
JESD8-C/JESD36 (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-B exceeds 200 V
CDM JESD22-C101E exceeds 1000 V
