Silan Semiconductors TX-2B/RX-2B REMOTE CONTROLLER WITH FIVE FUNCTIONS DESCRIPTION DIP-14 The TX-2B/RX-2B is a pair of CMOS LSIs designed for remote TX-2B controlled car applications. The TX-2B/RX-2B has five control keys for controlling the motions (i.e. forward, backward, rightward, leftward and the turbo function ) of the remote controlled car. FEATURES * Wide operating voltage range (VCC=1.5~5.0V) RX-2B * Low stand-by current DIP-16 * Auto-power-off function for TX-2B * Few external components are needed ORDERING INFORMATION Part No. Package TX-2B DIP-14-300-2.54 RX-2B DIP-16-300-2.54 BLOCK DIAGRAM OSCI 12 OSCO 11 RIGHT 1 LEFT 14 TURBO 6 FORWARD 5 BACKWARD 4 FOSC TEST B 13 2 Oscillator Timing Generator 9 VDD 10 PC Latch Circuit Encoding Circuit Logic 8 SO 7 SC 3 GND TRANSMITTER TX-2B Block Diagram HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD Rev: 1.0 1 2002.03.29 Silan Semiconductors TX-2B/RX-2B BLOCK DIAGRAM OSCI 4 Timing Generator Oscillator OSCO 5 SI 3 VO1 15 VI1 14 13 VDD Decoding Circuit AMP Computer PLA LDB 9 6 RIGHT Control Logic RDB 7 LEFT 8 VI2 16 VO2 1 12 TURBO Latch Circuit 10 BACKWARD 11 FORWARD 2 GND RECEIVER RX-2B Block Diagram PIN CONFIGURATION 14 LEFT VO2 1 16 VI2 TEST 2 13 FOSC GND 2 15 VO1 GND 3 12 OSCI SI 3 14 VI1 ACKWARD 4 11 OSCO OSCI 4 13 VDD FORWARD 5 10 PC OSCO 5 12 TURBO TURBO 6 9 VDD RIGHT 6 11 FORWARD SC 7 8 SO LEFT 7 10 BACKWARD ROB 8 9 LDB RX-2B 1 TX-2B RIGHT HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD Rev: 1.0 2 2002.03.29 Silan Semiconductors TX-2B/RX-2B ABSOLUTE MAXIMUM RATINGS Characteristic Symbol Value Unit VDD 0.3~5.0 V VIN, VOUT GND-0.3~VDD+0.3 V TOPR -10~65 °C Tstg -25~125 °C Supply Voltage Input / Output Voltage Operating Temperature Storage Temperature ELECTRICAL CHARACTERISTICS 1.
