The TLV703x-Q1 and TLV704x-Q1 input common-mode extends from V_EE to 100 mV above V_CC. The differential input voltage (V_ID) can be any voltage within these limits. No phase inversion of the comparator output occurs when the input pins exceed V_CC and V_EE.

The input of TLV703x-Q1 and TLV704x-Q1 is fault tolerant. It maintains the same high input impedance when V_CC is unpowered or ramping up. The input can be safely driven up to the specified maximum voltage (7 V) with V_CC = 0 V or any value up to the maximum specified. The V_CC is isolated from the input such that it maintains its value even when a higher voltage is applied to the input.

The input bias current is typically 1 pA for input voltages between V_CC and V_EE. The comparator inputs are protected from voltages below V_EE by internal diodes connected to V_EE. As the input voltage goes under V_EE, the protection diodes become forward biased and begin to conduct causing the input bias current to increase exponentially. Input bias current typically doubles every 10°C temperature increases.
