HD74LVC138
3-to-8-line Decoder / Demultiplexer
ADE-205-068B(Z)
Rev.2
September 1995
Description
The HD74LVC138 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.
