DESCRIPTION
The TS86x (Single, Dua l & Quad) is a Rail to Rail
comparator characterized for 2.7V to 10V opera-
tion over -40°C to +85°C temperature range. It exhibits an excellent speed to power ratio, fe aturing
a current consumption of 6µA per comparator and
a response time of 500ns at 2.7V for 100mV overdrive.
Due to its ultra low power consumption and its
availability in tiny package, the TS86x comparator
family is perfectly suited to battery powered systems. The output st age is designed with a push
pull structure allowing a direct connection to m icrocontroler without additionnal pull-up resistor.
APPLICATION
■ Battery-powered systems (eg: Alarm)
■ Portable communication systems
■ Smoke/gas/fire detectors
■ Portable computers
