Information about decoders and TTL data sheets. It explains that a decoder is a combinational circuit that converts binary information from n input lines to a maximum of 2n unique output lines. The document also includes a Google search for TTL data sheets and a list of Medium Scale Integration ICs.

Decoders^
A^ decoder
is a combinational circuit that converts binary information from
n^ input lines to a
maximum of
n^ 2 unique output lines.
For each possible input combination, there are n^2 output lines only one output is asserted (equalto 1). The output whose value is equal to 1 representsthe minterm equivalent of the binary numberpresently available in the input lines.

Some decoders are constructed with NANDgates. Decoders include one or more
enable
inputs to
control the circuit operation. A decoder with enable input can function as a demultiplexer
A demultiplexer is a circuit that receivesinformation from a single line and directs it to onen^ of 2^
possible output lines.
