Data Sheet  
AS1970 - AS1975  
Low-Voltage Single/Dual/Quad Comparators  
1 General Description  
2 Key Features  
CMOS Push/Pull Output Sinks and Sources 8mA  
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  
8.5µA) with minimal propagation delay (300ns).  
(AS1970/AS1972/AS1974)  
CMOS Open-Drain Output Voltage Extends Beyond  
VCC (AS1971/AS1973/AS1975)  
Quiescent Supply Current: 8.5µA per Comparator  
Internal Hysteresis: 3mV  
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.  
3V/5V Logic-Level Translation  
Single-Supply Operation: 2.5 to 5.5V  
Common-Mode Input Voltage Range Extends  
The comparators are available as the standard products  
listed in Table 1.

AS1970/AS1972/AS1974  
AS1971/AS1973/AS1975  
Open-Drain  
The AS1970/AS1972/AS1974 push/pull output can sink  
or source current.  
Package Types:  
- 5-pin SOT23 – AS1970/AS1971  
- 8-pin MSOP – AS1972/AS1973  
- 14-pin TSSOP – AS1974/AS1975  
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.  
3 Applications  
The devices are ideal for battery-powered systems,  
mobile communication devices, zero-crossing detectors,  
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.  
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.
