... The latch is reset with each clock pulse. The output stages are totem-pole designs capable of sourcing or sinking in excess of 200 mA. The SG3525A output stage features NOR logic, giving a LOW output for an OFF state. Type Plastic DIP SG2525A SG2525AN SG3525A SG3525AN SG2525A SG3525A 16(Narrow) SO16 SG2525AP SG3525AP 1/12 ...
