DESCRIPTIO
Ultralow Quiescent Current: 0.3µA Typ Reference Output Drives 0.01µF Capacitor Adjustable Hysteresis Available in 3mm x 3mm x 0.8mm DFN Package Wide Supply Range: 2V to 11V Input Voltage Range Includes the Negative Supply Reference Output Sources Up to 1mA TTL/CMOS Compatible Outputs 60µs Propagation Delay with 10mV Overdrive No Crowbar Current 40mA Continuous Source Current Pin Compatible with LTC1440, MAX921, MAX931
The LTC ®1540 is an ultralow power, single comparator with built-in reference.

The comparator's features include less than 0.6µA supply current over the commercial temperature range, a 1.182V ±2% reference, programmable hysteresis and TTL/CMOS outputs that sink and source current. The reference output can drive a bypass capacitor of up to 0.01µF without oscillation. The comparator operates from a single 2V to 11V supply or a dual ±1V to ±5.5V supply. Comparator hysteresis is easily programmed
