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

high speed, low power, and rail-to-rail inputs.

Propagation delay is 80ns, while supply current is only

350µA per comparator.

The input common-mode range of the MAX941/

MAX942/MAX944 extends beyond both power-supply

rails. The outputs pull to within 0.4V of either supply rail

without external pullup 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.

Internal hysteresis ensures clean output switching,

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

are available in 8-pin DIP and SO packages. The quad

MAX944 comes in 14-pin DIP and narrow SO packages.
