1 293D 293DD PUS-PU FOUR CANNE DRIVER WIT DIODES 600mA OUTPUT CURRENT CAPABIITY PER CANNE 1.2A PEAK OUTPUT CURRENT (non repetitive) PER CANNE ENABE FACIITY OVERTEMPERATURE PROTECTION OGICA "0" INPUT VOTAGE UP TO 1.5 V (IG NOISE IMMUNITY) INTERNA CAMP DIODES DESCRIPTION The Device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DT or TT logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors. To simplify use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included. This device is suitable for use in switching applications at frequencies up to 5 kz. SO(12+4+4) Powerdip (12+2+2) 293DD ORDERING NUMBERS: 293D The 293D is assembled in a 16 lead plastic packaage which has 4 center pins connected together and used for heatsinking The 293DD is assembled in a 20 lead surface mount which has 8 center pins connected together and used for heatsinking.
