Data Sheet  
AS1976, AS1977  
Ultra-Low Current, 1.8V Comparators  
1 General Description  
2 Key Features  
CMOS Push/Pull Output Sinks and Sources 8mA  
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  
(AS1976)  
CMOS Open-Drain Output Voltage Extends Beyond  
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.  
VCC (AS1977)  
Ultra-Low Supply Current: 200nA  
Internal Hysteresis: 3mV  
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.  
Crowbar Current-Free Switching  
No Phase Reversal for Overdriven Inputs  
5-pin SOT23 Package  
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.  
3 Applications  
The AS1976/AS1977 are available in a 5-pin SOT23  
package.  
The devices are ideal for battery monitoring/manage-  
ment, mobile communication devices, laptops and  
PDAs, ultra-low-power systems, threshold detectors/dis-  
criminators, telemetry and remote systems, medical  
instruments, or any other space-limited application with  
low power-consumption requirements.
