TX-5B

Silan Semiconductors REMOTE CONTROLLER WITH SEVEN FUNCTIONS DESCRIPTION The TX-5B/RX-5B are a pair of CMOS LSIs designed for remote controlled car applications. They have nine control keys controlling the motions (i.e. forward, backward, rightward, leftward, trigger 1-trigger 4 functions and the turbo function) of the remote controlled car. The TX-5B is housed in DIP-16 package, and the RX-5B is housed in DIP-22 package. TX-5B/RX-5B DIP-16 DIP-22 FEATURES * Wide operating voltage range TX-5B: (VDD=2.2~12.0V) RX-5B: (VDD=3.0~12.0V) * Very Low stand-by current for TX-5B * Auto-power-off function for TX-5B * Few external components are needed * Built-in 3.6V zener for RX-5B * 9 functions remote controller controlling: forward,backward, right, left, turbo, trigger 1-- trigger 4 functions ORDERING INFORMATION Part No. TX-5B/RX-5B Package DIP-16-300-2.54 DIP-22-400-2.54 PIN CONFIGURATION VO2 GND RIGHT TEST GND BACKWARD FORWARD TURBO SC F34 1 2 3 4 5 6 7 8 9 10 11 22 21 20 19 18 VI2 VO1 VI1 VDD TURBO F3 FORWAR F4 BACKWAR LRTD LDB 1 2 3 4 5 6 7 8 16 15 14 13 LEFT SI F1 OSCI OSCI OSCO OSCO F1 PC RIGHT VDD F2 SO LEFT F2 VT RDB RX-5B 17 16 15 14 13 12 TX-5B 12 11 10 9 HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD Rev: 2.0 2002.03.26 1 Silan Semiconductors BLOCK DIAGRAM TEST TX-5B/RX-5B 2 OSCI 14 Oscillator 13 Timing Generator OSCO RIGHT 1 16 6 5 4 Latch Circuit Encoding Circuit Logic 11 VDD LEFT 12 PC 10 SO 7 SC TURBO FORWARD BACKWARD 15 F1 9 F2 8...
