_______________General Desc ription
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 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.
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 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.
