DESCRIPTION OF OPERATION
2 Refer to the Timing Chart below. In normal steady-state
operation, when VIN > VD– ET, the output will be at a logic high.
In the case of the TC54V, this is an open-drain condition. If
and when the input falls below VD– ET, 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
the Electrical Characteristics section).
3 The output, VOUT, will stay valid until the input voltage
falls below the Minimum Operating Voltage, VIN(MIN), of
1.5V. Below this minimum operating voltage, the output is
undefined. During power-up or anytime VIN has fallen below
VIN (MIN), VOUT will remain undefined until VIN rises above
VIN(MIN), at which time the output will become valid. VOUT
will be in its active low state while VIN(MIN) < VIN < VD+ET.
(V+DET = VD–ET + VHYST). If and when the input rises above
V+DET, the output will assume its inactive state. (High for
TC54VC, open-drain for TC54VN).
