DESCRIPTION
TheTS861 isaRAILTORAILsingleBiCMOScomparator optimized and fully specified for 2.7V, 5V
and 10V operations.
The TS861 exhibits an excellent speed to power
consumptionratio, making this device an excellent
choice for battery operated systems.
The TS861 has a push-pull output allowing direct
connectionto microcontroller without pull-upresistors.
APPLICATIONS
.Cordless telephones and portable communica-
tion equipments
.Metering systems
.Portable computers
.Battery powered alarms

Notes : 1. All voltages values, except differential voltage, are with respect to networkground terminal.
2. Differential voltages are non-inverting inputterminal with respect to the inverting inputterminal.
3. The magnitude of inputand output voltages must never exceedVCC+0.3V.
