HES3017

HES3017 HES30 SERIES HES-3017 REMOTE CAR CONTROLLER RX 1. General Description The HES-3017 is a CMOS LSI designed for remote controlled car RX applications. Combined with HES-3018, 5 function motions (i.e. forward, backward, rightward, leftward and turbo function) of the remote controlled car can be implemented. 2. Features u u u u u Auto-centering steering. Few external components are needed. Low stand-by current. RC oscillator. Wide operating voltage range: 2.5V~5.5V. 3.
