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