General Description
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
350A 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 MAX 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 packages.
