8 V C o m pa r a t o r s D a ta S he e t 1 General Description The AS1976/AS1977 are very low-current comparators that can operate beyond the rail voltages and are guaranteed to operate down to 1.
8V Low input bias current, current-limiting output circuitry, and ultra-small packaging make these comparators ideal for low-power 2-cell applications including powermanagement and power-monitoring systems.
The comparators are available as the standard products listed in Table 1.
