RD74LVC138B
3-to-8-line Decoder / Demultiplexer
REJ03D0502–0200
Rev.2.00
Jan. 14, 2005
Description
The RD74LVC138B has three binary select inputs in a 16 pin package. If the device is enabled these inputs determine
which one of the eight normally high outputs will go low. Two active low and one active high enables are provided to
ease the cascading of decoders. 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.
