The MAX941/MAX942/MAX944 are single/dual/quad  
high-speed comparators optimized for systems pow-  
ered from a 3V or 5V supply. These devices combine  
hig h s p e e d , low p owe r, a nd ra il-to-ra il inp uts .  
Propagation delay is 80ns, while supply current is only  
350µA per comparator.  
Available in µMAX Package  
Optimized for 3V and 5V Applications  
(operation down to 2.7V)  
Fast, 80ns Propagation Delay (5mV overdrive)  
Rail-to-Rail Input Voltage Range  
The inp ut c ommon-mod e ra ng e of the MAX941/  
MAX942/MAX944 extends beyond both power-supply  
rails. The outputs pull to within 0.4V of either supply rail  
without external pull-up circuitry, making these devices  
ideal for interface with both CMOS and TTL logic. All  
input and output pins can tolerate a continuous short-  
circuit fault condition to either rail.  
Low Power:  
1mW Power Dissipation per Comparator (3V)  
350µA Supply Current  
Low, 1mV Offset Voltage  
Internal Hysteresis for Clean Switching  
Outputs Swing 200mV of Power Rails  
CMOS/TTL-Compatible Outputs  
Output Latch (MAX941 only)  
Inte rna l hyste re sis e nsure s c le a n outp ut switc hing,  
even with slow-moving input signals. The MAX941 fea-  
tures latch enable and device shutdown.  
The single MAX941 and dual MAX942 are offered in a  
tiny µMAX package. Both the single and dual MAX942  
are available in 8-pin DIP and SO packages. The quad  
MAX944 comes in 14-pin DIP and narrow SO pack-  
ages.
