UNISONIC TECHNOLOGIES CO., LTD RCT6 CMOS IC www.unisonic.com.tw 1 of 8 Copyright © 2005 Unisonic Technologies Co., Ltd QW-R502-058,A REMOTE CONTROLLER WITH SEVEN FUNCTIONS „ DESCRIPTION The UTC RCT6 is a pair of CMOS LSIs designed for remote controlled car applications. The UTC RCT6 have seven control keys controlling the motions (i.e. forward, backward, rightward, leftward, two function keys, and the turbo fu nction) of the remote controlled car. UTC RCT6 have Forward (Backward) combined with the turbo application. The UTC RCT6 is the sending electric circuit. „ FEATURES * Operating voltage range: 2.0V ~ 5.0V * Very low Stand-by current * Few external components needed * 7-function remote controller controlling Forward/Backward/Turbo/ Right-turn/Left turn/two function keys DIP-16 *Pb-free plating product number: RCT6L „ ORDERING INFORMATION Order Number Normal Lead Free Plating Package Packing RCT6-D16-T RCT6L-D16-T DIP-16 Tube RCT6L-D16-T (1)Packing Type (2)Package Type (3)Lead Plating (1) T: Tube (2) D16: DIP-16 (3) L: Lead Free Plating , Blank: Pb/Sn
