LTC8721YT5/R6

The LTC8721/LTC8722/LTC8723 are tiny, single- and dual- channel comparators with push-pull output that offer the ultimate combination of high speed (66 ns propagation delay) and very low power consumption (22μA), available in extremely small packages with features such as rail-to-rail inputs, low offset voltage (0.8 mV), large output drive current, and a wide range of supply voltages from 1.7 V to 5.5 V. The devices are very easy to implement in a wide variety of applications where require critical response time, power-sensitive, low-voltage, and/or tight board space. The output of the LTC8721/LTC8722/LTC8723 pulls to within 0.1 V of either supply rail without external pull-up circuitry, making these devices ideal for interface with both CMOS and TTL logics. All input and output pins can tolerate a continuous short-circuit fault condition to either rail. Internal hysteresis ensures clean output switching, even with slow-moving input signals. The LTC8721/LTC8723 (single) is available in both SOT23-5L and SC70-5L packages. The LTC8722 (dual) is offered in DFN-8L, SOIC-8L and MSOP-8L packages. All devices are rated over -40 °C to +85 °C industrial temperature range.
