NTE1749
Integrated Circuit
Push鈥揚(yáng)ull Four Channel Driver
Description:
The NTE1749 is a quad push鈥損ull driver capable of delivering output currents to 1A per channel.
Each channel is controlled by a TTL鈥揷ompatible 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.
