DETAILED DESCRIPTION
The output (V OUT ) will stay valid until the input voltage
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 TC54VN, this is an open-drain condition. If
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
V IN
falls below the minimum operating voltage (V INMIN ) of
0.7V. Below this minimum operating voltage, the output
is undefined. During power-up (or anytime V IN has
fallen below V INMIN ), V OUT will remain undefined until
V IN rises above V INMIN . When this occurs, the output
will become valid. V OUT will be in its Active-low state,
while V INMIN < V IN < V DET + (therefore, V DET + = V DET –
+ V HYST ). If the input rises above V DET +, the output will
assume its Inactive state (high for TC54VC, open-drain
for TC54VN).
