Linear Technology LTC1042
the LTC1042 is the extremely low power consumption. When the device is strobed, it internally turns on the power to the comparators, samples the inputs, stores the outputs in CMOS latches and then turns off power to the comparators. This all happens in about 80µs.FEATURES

DESCRIPTIO The LTC®1042 is a monolithic CMOS window comparator manufactured using Linear Technology’s enhanced LTCMOS™ silicon gate process. Two high impedance voltage inputs, CENTER and WIDTH/2, define the middle and width of the comparison window. Whenever the input voltage, VIN, is inside the window the WITHIN WINDOW output is high. The ABOVE WINDOW output is high whenever VIN is above the window. By interchanging VIN and CENTER, the ABOVE WINDOW output becomes BELOW WINDOW and is high if VIN is below the window.
