A1373 and A1374
The midrange voltage level, V
PM
, is a neutral level, used to
separate both V
PH
and V
PL
pulses from each other. The nominal
level for V
PM
is 15 V.
The low level, V
PL
, pulse is used to indicate bitfield addresses
that are to be set. The device generates an internal pulse begin-
ning at the leading (falling) edge of a V
PL
pulse. The duration
of the internal pulse is 5
μ
s. Before allowing the voltage to
rise again, an additional guard band of 1
μ
s is recommended to
ensure that the pulse completes, for a total of at least 6
μ
s after
the start of any V
PL
pulse. The duration of the V
PL
pulse,
Δ
t
PL
,
is measured from the time when the external signal voltage falls
into the range 0 to 7.5 V to the time when it rises above 10 V. If
the voltage rises above 10 V before the 5
μ
s period expires, then
the V
PL
pulse will immediately end, with undefined results. The
nominal level for V
PH
is 5 V.
V
PL
must always be maintained high enough above V
R
(nomi-
nally 0 V) to maintain the settings provisionally latched into
registers. Note that, when the external voltage rises from V
R
through the V
PL
range, a spurious internal pulse is generated,
making Code 0 not available in Mode Selection state. A spurious
internal pulse also is generated when the external voltage falls
through the V
PL
range at the end of a code sequence. For that
reason, it is mandatory to ensure that the voltage is dropped fully
to V
R
, before every Blow Fuse mode operation, to ensure that
the spurious pulse does not affect the next code sequence.
