1 General Description
The AS1970 - AS1975 are single/dual/quad compara-
tors that operate with supplies from 2.5 to 5.5V making
them perfect for all 3- and 5-volt applications. The com-
parators can also operate with dual supplies (±1.25 to
±2.75V), and require very little supply current (down to
8.5A) with minimal propagation delay (300ns).
Low input bias current (1.0pA, typ), low input offset volt-
age (0.5mV, typ), and internal hysteresis (3mV) make
these comparators ideal for low-power single-cell appli-
cations including power-management and power-moni-
toring systems.
The comparators are available as the standard products
listed in Table 1.
The AS1970/AS1972/AS1974 push/pull output can sink
or source current.
The AS1971/AS1973/AS1975 open-drain output can be
pulled beyond VCC to a maximum of 5.5V > VEE. These
open-drain versions are ideal for logic-level translators
or bipolar-to-unipolar converters.
Large internal output drivers allow Rail-to-Rail output
swings with loads of up to 8mA.
The AS1970/AS1971 are available in a 5-pin SOT23
package. The AS1972/AS1973 are available in a 8-pin
MSOP package. The AS1974/AS1975 are available in a
14-pin TSSOP package.

3 Applications
The devices are ideal for battery-powered systems,

window comparators, level translators, threshold detec-
tors/discriminators, ground/supply-sensing applications,
IR receivers or any other space-limited application with
low power-consumption requirements.
