MAX941ESA

The MAX941ESA belongs to MAX941/MAX942/MAX944 family which are single/dual/quad high-speed comparators optimized for systems powered from a 3V or 5V supply. 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 and 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. 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 pack- ages.

The features of MAX941ESA can be summarized as (1)available in MAX package; (2)optimized for 3V and 5V applications (operation down to 2.7V); (3)fast, 80ns propagation delay (5mV overdrive); (4)rail-to-rail input voltage range; (5)low power: 1mW power dissipation per comparator (3V), 350A supply current; (6)low, 1mV offset voltage; (7)internal hysteresis for clean switching; (8)outputs swing 200mV of power rails; (9)CMOS/TTL-compatible outputs; (10)output latch (MAX941 only); (11)shutdown function (MAX941 only).
