DETAILED DESCRIPTION
In normal steady-state operation, when VIN > VDET -,
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 VDET -, the output will
pull down (Logic 0) to VSS. Generally, VOUT can pull
down to within 0.5V of VSS at rated output current and
input
voltage.
(See
Electrical
Characteristics).
The output, VOUT, will stay valid until the input voltage
falls below the minimum operating voltage, VINMIN, of
0.7V. Below this minimum operating voltage, the output
is undefined. During power-up or anytime VIN has fallen
below VINMIN, VOUT will remain undefined until VIN rises
above VINMIN, at which time the output will become
valid. VOUT will be in its active low state while VINMIN <
VIN < VDET+. (VDET+ = VDET - + VHYST). If and when
the input rises above VDET+, the output will assume its
inactive state. (High for TC54VC, open-drain for
TC54VN).
