Description
The TS86x device (single, dual and quad) is
a rail-to-rail comparator characterized for 2.7 to
10 V operation over -40 °C to +85 °C temperature
ranges. It exhibits an excellent speed-to-power
ratio, featuring a current consumption of 6 μA per
comparator and a response time of 500 ns
at 2.7 V for a 100 mV overdrive.
Due to its ultra low power consumption and its
availability in a tiny package, the TS86x
comparator family is perfectly suited to battery-
powered systems. The output stage is designed
with a push-pull structure allowing a direct
connection to the microcontroller without
additional pull-up resistors.

5. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through
a 1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin
combinations while the other pins are floating.
6. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while the other pins are floating.
