NTE7091
Integrated Circuit
Dual, Bi鈥揇irectional Motor Driver
Description:
The NTE7091 is an integrated circuit in a 10鈥揕ead SIP type package designed for forward/reverse
direction select driver by switching motor 1 or motor 2 with a brush. Forward/reverse direction select
of motor 1 or motor 2 can be made by 3鈥揵it input logic. It also assures five outputs of both brakes
and is suitable for VCR tape loading and cassette loading, video disc players, etc.
