NTE1749 Integrated Circuit Push–Pull Four Channel Driver
Description: The NTE1749 is a quad push–pull driver capable of delivering output currents to 1A per channel. Each channel is controlled by aTTL–compatible 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 itmay be run off a lower voltage to reduce dissipation.
