Operating with supplies from 1.4V up to 18V, these devices draw only 6.5µA typical, making them ideal for low voltage system monitoring. Hysteresis is included in the parators, easing design requirements to insure stable output operation. The parators each have one input available externally, the other inputs are connected internally to the reference. The parator outputs are open collector and the output load can be referred to any voltage up to 18V, independent of supply voltage. The output stage sinking capability is guaranteed greater than 5m A over temperature.

The LT6700-1 has one inverting input and one noninverting input, making it suitable for use as a window parator. The LT6700-2 has two inverting inputs and the LT6700-3 has two noninverting inputs.
