SEMICONDUCTOR TECHNICAL DATA
The MC10161 is designed to decode a three bit input word to a one of eight
line output. The selected output will be low while all other outputs will be high. The
enable inputs, when either or both are high, force all outputs high.
The MC10161 is a true parallel decoder. No series gating is used internally,
eliminating unequal delay times found in other decoders. This design provides
the identical 4 ns delay from any address or enable input to any output.
A complete mux/demux operation on 16 bits for data distribution is illustrated
in Figure 1. This system, using the MC10136 control counters, has the
capability of incrementing, decrementing or holding data channels. When both
S0 and S1 are low, the index counters reset, thus initializing both the mux and
demux units. The four binary outputs of the counter are buffered by the
MC10101s to send twisted–pair select data to the multiplexer/demultiplexer to
units.

Each MECL 10,000 series circuit has been designed to meet the dc specifications shown in the test table, after thermal equilibrium has been
established. The circuit is in a test socket or mounted on a printed circuit board and transverse air flow greater than 500 linear fpm is maintained.
Outputs are terminated through a 50–ohm resistor to –2.0 volts. Test procedures are shown for only one gate. The other gates are tested in the
same manner.
