MAX941

19-0229; Rev 3; 6/97 High-Speed, Low-Power, 3V/5V, Rail-to-Rail Single-Supply Comparators _______________General Description The MAX941/MAX942/MAX944 are single/dual/quad high-speed comparators optimized for systems powered 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 shortcircuit fault condition to either rail. Internal hysteresis ensures clean output switching, even with slow-moving input signals. The MAX941 features 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 packages. ____________________________Features o Available in µMAX Package o Optimized for 3V and 5V Applications (operation down to 2.7V) o Fast, 80ns Propagation Delay (5mV overdrive) o Rail-to-Rail Input Voltage Range o Low Power: 1mW Power Dissipation per Comparator (3V) 350µA Supply Current o Low, 1mV Offset Voltage o Internal Hysteresis for Clean Switching o Outputs Swing 200mV of Power Rails o CMOS...
