RD74LVC139B
Dual 2-to-4-line Decoders / Demultiplexers
REJ03D0503–0100
Rev.1.00
Dec. 02, 2004
Description
The RD74LVC139B has two independent two-to-four-line decoders each with a single active low enable input in a 16
pin package. Data on the select inputs cause one of the four normally high outputs to go low. Low voltage and high-
speed operation is suitable at the battery drive product (note type personal computer) and low power consumption
extends the life of a battery for long time operation.
