2549中文资料ALLEGRO数据手册PDF规格书

Providing improved output current limiting, the UDK/UDN/UDQ2549B and UDK/UDN/UDQ2549EB quad power drivers combine AND logic gates and high-current bipolar outputs with complete output protection. Each of the four outputs will sink 600 mA in the on state. The outputs have a minimum breakdown voltage (load dump) of 60 V and a sustaining voltage of 40 V. The inputs are compatible with TTL and 5 V CMOS logic systems.
