NTE7091 Integrated Circuit Dual, Bi–Directional Motor Driver Description: The NTE7091 is an integrated circuit in a 10–Lead 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–bit input logic. It also assures five outputs of both brakes and is suitable for VCR tape loading and cassette loading, video disc players, etc. Features: D Wide Range of Operating Supply Voltage: VCC(opr) = 4V to 20V D Forward and Reverse Drive of Motor 1 or Motor 2 by 3–Bit Input. D Built–In Thermal Protection Circuit.
