A small
circle at the input or output
of a symbol
indicates that the LO
state
is
the significant
state. Absence
of
the circle
indicates that the HI
state
is the significant state. Two
examples follow:
AND
gate
with LO-state
indicator
at
the A
input.
The

of this gate is HI if and

The
output of
this gate is HI if
either
the
A
input
is LO or the B
input
is HI.
Normally
superimposed

an input
line to a logic symbol. Indicates that
this input
(usually the

of a
flip flop) responds to the

A
bistable device
with
one input
and
two
outputs (either
or
both
outputs may
be used). When
trig
gered,
the outputs change from one
stable state
to the other stable state
with each
trigger. The outputs
are
complementary
(i.e., when one out
put
is
HI the other is LO). The edge
symbol
on the trigger (T) input
may
be of either polarity depending
on
the device.
