At supply voltages of 2.7V, the common-mode voltage range extends 200 mV (guaranteed) below the negative

supply. This feature, in addition to the comparator being able to sense signals near the positive rail, is extremely

useful in low voltage applications.

Figure 3. Even at Low-Supply Voltage of 2.7V, an Input Signal which Exceeds the Supply Voltages

Produces No Phase Inversion at the Output

At V+ = 2.7V propagation delays are tPLH = 4 μs and tPHL = 4 μs with overdrives of 100 mV.

Please refer to the performance curves for more extensive characterization.

Shoot-Through Current

The shoot-through current is defined as the current surge, above the quiescent supply current, between the

positive and negative supplies of a device. The current surge occurs when the output of the device switches

states. The shoot-through current results in glitches in the supply voltages. Usually, glitches in the supply lines

are prevented by bypass capacitors. When the glitches are minimal, the value of the bypass capacitors can be

reduced.
