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.
♦ Shutdown Function (MAX941 only)
