NTE1749 Integrated Circuit PushPull Four Channel Driver Description: The NTE1749 is a quad pushpull driver capable of delivering output currents to 1A per channel. Each channel is controlled by a TTLcompatible logic input and each pair of drivers (a full bridge) is equipped with an inhibit input which turns off all four transistors. A separate supply input is provided for the logic so that it may be run off a lower voltage to reduce dissipation.
