November 2012 Doc ID 6422 Rev 3 1/19 19 TS861, TS862, TS864 Rail-to-rail micropower BiCMOS comparators Datasheet − production data Features ■ Ultra low current consumption (6 µA/comp. at VCC = 2.7 V) ■ Rail-to-rail CMOS inputs ■ Push-pull outputs ■ Supply operation from 2.7 to 10 V ■ Low propagation delay ■ ESD protection (2 kV) ■ Latch-up immunity (class A) ■ Available in SOT23-5 micropackage, SO-8, SO-14,TSSOP8, and TSSOP14 package Applications ■ Battery powered systems such as alarms ■ Portable communication systems ■ Smoke/gas/fire detectors ■ Portable computers 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. 8 6 Vcc- 1 2 Non-inverting input 1 3 4 7 5 Inverting input 1 Output 2 Vcc+ + - + - Non-inverting input 2 Output 1 Inverting input 2 + - + - + - + - SOT23-5 SO-8, TSSOP8 (dual) 5 4 Output Vcc- 1 2 Non-inverting input Vcc+ 3 + - Inverting input 8 6 Vcc- 1 2 Non-inverting input 3 + - 4 7 5 Inverting input Output Vcc+ NC NC NC + - + - 14 12 Vcc- 1 2 Non-inverting input 3 3 4 13 11 Inverting input 3 Output 4 + - + - Non-inverting input 2 Output 2 Inverting input 410 8 9 Output 3 Vcc+ Inverting input 2 5 6 Non-inverting input 1 7 Inverting input 1 Output 1 + - + - Non-inverting input 4 + - + - + - + -+ - + - + - + - SO-14, TSSOP14 (quad) SO-8 (single) www.st.com

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. 2 200 kV V Latch-up immunity Class A Table 2.
