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 a TTL–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 it may be run off a lower voltage to reduce dissipation.
Features:
D Output Current 1A Per Channel
D Peak Output Current 2A Per Channel (Non Repetitive)
D Inhibit Facility
D High Noise Immunity
D Separate Logic Supply
D Overtemperature Protection
