DETAILED DESCRIPTION
In normal steady-state operation, when V
IN
> V
DET
-,
the output will be at a logic high, see Figure 3-1. In the
case of the TC54V, this is an open-drain condition. If
and when the input falls below V
DET
-, the output will
pull down (Logic 0) to V
SS
. Generally, V
OUT
can pull
down to within 0.5V of V
SS
at rated output current and
input
voltage.
(See
Characteristics).
Section 1.0,
Electrical
The output, V
OUT
, will stay valid until the input voltage
falls below the minimum operating voltage, V
IN
MIN
, of
0.7V. Below this minimum operating voltage, the output
is undefined. During power-up or anytime V
IN
has fallen
below V
IN
MIN
, V
OUT
will remain undefined until V
IN
rises
above V
IN
MIN
, at which time the output will become
valid. V
OUT
will be in its active low state while V
IN
<
V
IN
< V
DET
+. (V
DET
+
= V
DET
- + V
HYST
). If and when
the input rises above V
DET
+, the output will assume its
inactive state. (High for TC54VC, open-drain for
TC54VN).
