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 of HD74LVC138 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.
