TX7/RX7

DIGITAL PROPORTIONAL REMOTE

CONTROLLER

DESCRIPTION

The TX7/RX7 are a pair of IC designed for digital proportional

radio control system, where TX7 is the transmitter and RX7 is the

receiver. The TX7/RX7 provide a 3-channel remote controller for

DIP-14

TX7

digital remote controlled car application. TX7/RX7 have 3 channels,

CH1, CH2 and CH3. CH1 is a digitized control handling forward and

backward motions, where 7 steps controlling motor forward speed,

and another 7 steps for backward speed. CH2 is a digitized

proportional control used to steer servo-motor consisted of 32 steps

to drive angles in left and right directions. CH3 is the ON/OFF

RX7 DIP-16

control. In addition, RX7 also provides auto power-off function to

detect excessive current of forward/backward motor under special

conditions according to toy safety requirements.
