L293D, L293DD PUSH-PULL FOUR CHANNEL DRIVER WITH DIODES
■The Device is a monolithic integrated high volt-age, high current four channel driver designed to accept standard DTL or TTL 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 di-odes are included.
■This device is suitable for use in switching applications at frequencies up to 5 kHz.
■The L293D is assembled in a 16 lead plastic package which has 4 center pins connected together and used for heatsinking.
■The L293DD is assembled in a 20 lead surface mount which has 8 center pins connected together and used for heatsinking.
■600mA OUTPUT CURRENT CAPABILITY PER CHANNEL
■1.2A PEAK OUTPUT CURRENT (non repetitive) PER CHANNEL
■ENABLE FACILITY
■OVERTEMPERATURE PROTECTION
■LOGICAL "0" INPUT VOLTAGE UP TO 1.5 V (HIGH NOISE IMMUNITY)
■INTERNAL CLAMP DIODES
