3185, HALL-EFFECT LATCHES

3185 THRU 3189 HALL-EFFECT LATCHES FOR HIGH-TEMPERATURE OPERATION These Hall-effect latches are extremely temperature-stable and stressresistant sensors especially suited for operation over extended temperature ranges to +150°C.

Superior high-temperature performance is made possible through a novel Schmitt trigger circuit that maintains operate and release point symmetry by compensating for temperature changes in the Hall element.

Additionally, internal compensation provides magnetic switch poi
