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 TC54VN, 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 Section 1.0, “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. Once this occurs, 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).
