Product Description
Pericom Semiconductor’s PI74LVC series of logic circuits are
produced using the Company’s advanced 0.5 micron CMOS
technology, achieving high speed while maintaining low-power
operation.
The PI74LVC139A comprises two individual 2-line to 4-line decoders
in a single package. The active-low enable (G) input can be used as
a data line in demultiplexing applications. These decoders/
demultiplexers feature fully buffered inputs, each of which represents
only one normalized load to its driving circuit.
Inputs can be driven from either 3.3V or 5.0V devices allowing the
PI74LVC139A to be used as a translator in a mixed 3.3V/5.0V system.

Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the
device. This is a stress rating only and functional
operation of the device at these or any other con-
ditions above those indicated in the operational
sections of this specification is not implied. Expo-
sure to absolute maximum rating conditions for
extended periods may affect reliability.
