NTE1749−1
Integrated Circuit
Push−Pull Four Channel Driver with Diodes
16−Lead DIP
Description:
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.
Features:
D 600mA Output Current Capability Per Channel
D 1.2A Peak Output Current Per Channel (Non Repetitive)
D Enable Facility
D Overtemperature Protection
D Logical “0” Input Voltage up to 1.5V (High Noise Immunity)
D Internal Clamp Diodes
