1 General Description
The AS1976/AS1977 are very low-current comparators
that can operate beyond the rail voltages and are guar-
anteed 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 power-
management and power-monitoring systems.
The comparators are available as the standard products
listed in Table 1.
The AS1976 push/pull output can sink or source current.
The AS1977 open-drain output can be pulled beyond
VCC to a maximum of 6V > VEE. This open-drain model
is ideal for use as a logic-level translator or bipolar-to-
unipolar converter.
Large internal output drivers provide rail-to-rail output
swings with loads up to 8mA. Both devices feature built-
in battery power-management and power-monitoring cir-
cuitry.
The AS1976/AS1977 are available in a 5-pin SOT23
package.

criminators, telemetry and remote systems, medical
instruments, or any other space-limited application with
low power-consumption requirements.
