Detailed Description

The 74LVC138AD is a 3-Line to 8-Line decoder/Demultiplexer.

Actually this class provides access to the 25AA02E64 2K SPI Bus Serial EEPROM with EUI-64 Node Identity, holding 2048 bits = 256 bytes of meta data and identification material (see also Deliverable D3.2 section 3.1). This is represented by the the MetadataMemory<256> base class.
