The NTE1749−1 is a monolithic integrated high voltage, high current four channel driver in a 16−Lead DIP type package designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays, solenoids, 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. The NTE1749−1 is suitable for use in switching applications at frequencies up to 5kHz.
