Diode (CR)
The diode block specifies a diode. For a zener diode, the
breakdown voltage
is also specified. The edge-of-block
character X indicates
the anode connection.

Power Block (PWR)
The power block generates signal levels. No polarity
assignment
is made to the signal outputs. Voltage levels
are placed inside
the block adjacent to their respective
output. Nonlogic lines, such as a bias or shield, are
indicated by
an edge-of-block character X.

FUNCTIONAL LOGIC BLOCKS WITH COMMON INPUTS
Functional logical blocks with common inputs have a data
section and a common section
as shown in the illustration.
The data section is a group of stacked functional blocks.
The common section contains input lines common
to all
functions.

Common (COM)
Common is a way of condensing logic. Common inputs are
indicated by
the line function symbol Z. The Z input line
enters
the common section of the logic block and the
specified Z (1, 2, or 3) designation is repeated in all the
functional blocks affected. However, if a common input
is common to all the data blocks, it might not be labeled
at all, or it might be labeled Z only.

Selector (SE L)
The selector is a gating device. The common section of the
block contains the gates. These lines are designated G1, G2,
... Gn. The lower section contains the gated data lines. In
the following illustration, G1 and G2 are input gates and G3
is an output gate as indicated by their position in the data
block.
