Description:

The GD30CP872x are tiny, single-channel and dualchannel comparators with push-pull output that offer theultimate combination of high speed (66ns propagationdelay) and very low power consumption (22μA),available in extremely small packages with featuressuch as rail-to-rail inputs, low offset voltage (0.8mV),large output drive current, and a wide range of supplyvoltages from 1.7V to 5.5V. The devices are very easyto implement in a wide variety of applications whererequire critical response time, power-sensitive, lowvoltage, and/or tight board space.The output of the GD30CP872x pulls to within 0.1Vof either supply rail without external pull-up circuitry, making these devices ideal for interface with bothCMOS and TTL logics. All input and output pins can tolerate a continuous short-circuit fault conditionto either rail. Internal hysteresis ensures clean output switching, even with slow-moving input signals.The GD30CP8721/GD30CP8723 (single) is available inboth SOT23-5L and SC70-5L packages. TheGD30CP8722 (dual) is offered in DFN-8L, SOIC-8L andMSOP-8L packages. All devices are rated over −40°C to+125°C industrial temperature range.
