HS-54C138RH
Typical applications include systems which require multiple
input/output ports and memories. When the HS-54C138RH
is enabled one of the eight outputs will go low. This output
can be used to select a particular device or a group of
devices. The HS-54C138RH can also be cascaded to
provide an enabling scheme for larger systems and allow
one decoder to control eight other decoders as in Figure 1.
Figure 2 shows a configuration that can be used to enable
multiple I/O ports or memory devices. Up to 24 memory
devices or I/O ports can be controlled using this circuit.
For demultiplexer operation, one of the three enable inputs is
used as the data input while the other two inputs are enable.
The transmitted data is distributed to the proper output as
determined by the 3-line select inputs. See Figure 3.
