9.4.4 TLV3011B and TLV3012B Fail-Safe inputs

The TLV3011B and TLV3012B inputs are Fail-Safe up to 5.5V independent of V+ voltage. Fail-Safe is defined as maintaining the same high input impedance when V+ is unpowered or within the recommended operating ranges.

The Fail-Safe inputs can be any value between 0 V and 5.5 V, even while V+ is zero or ramping up or down. This feature avoids power sequencing issues as long as the input voltage range and supply voltage are within the specified ranges. This is possible since the inputs are not clamped to V+ and the input current maintains its value even when a higher voltage is applied to the inputs.

As long as one of the input pins remains within the valid input range, and the supply voltage is valid and not in POR, the output state will be correct.

The following is a summary of the TLV3011B and TLV3012B device input voltage excursions and their outcomes:

  1. When both IN- and IN+ are within the specified input voltage range:
    1. If IN- is higher than IN+ and the offset voltage, the output is low.
    2. If IN- is lower than IN+ and the offset voltage, the output is high.
  2. When IN- is higher than the specified input voltage range and IN+ is within the specified voltage range, the output is low.
  3. When IN+ is higher than the specified input voltage range and IN- is within the specified input voltage range, the output is high
  4. When IN- and IN+ are both outside the specified input voltage range, the output state is indeterminate (random). Do not operate in this region.
Because the inputs do not have upper ESD diode clamps to V+, input voltages must be externally clamped to below 5.5 V if the source could possibly exceed 5.5 V. A current limiting resistor in series with the input is also recommend in case of input transients.
