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 highspeed 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.
