RX-3

Silan Semiconductors REMOTE CONTROLLER WITH TWO FUNCTIONS DESCRIPTION The RX-3 is a CMOS LSIs designed for remote controlled car applications. The RX-3 has only 2 keys with 3 states, i.e. forward key for forward function, backward key for backward function, and stop function if there is no signal. RX-3 FEATURES * Wide operating voltage range (VCC=2.2 ~ 12V) * Few external components are needed * Typical oscillator frequency 76KHz * RX-3 built-in Zener 3V * 2 functions remote controller including forward/backward DIP-16 ORDERING INFORMATION Part No. RX-3 Package DIP-16-300-2.54 PIN CONFIGURATION BLOCK DIAGRAM OSCI 5 VO2 NC GND SI OSCI NC OSCO BACKWARD 1 2 3 4 16 15 14 13 VI2 Oscillator OSCO 7 Timing Generator TESTB VO1 Counter VI1 NC SI 4 AMP Decoding Circuit 12 VDD RX-3 5 6 7 8 12 11 10 9 VDD FORWARD NC PLA VO1 15 VI1 14 8 BACKWARD VI2 16 NC Control Logic Latch Circuit 11 FORWARD VO2 1 3 GND HANGZHOU SILAN MICROELECTRONICS CO.,LTD Rev: 1.0 2000.12.31 1 www.DataSheet4U.com Silan Semiconductors PIN DESCRIPTION Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 RX-3 Description Symbol VO2 NC GND SI OSCI NC OSCO BACKWARD NC NC FORWARD VDD NC VI1 VO1 VI2 No connection Negative power supply Input pin of the encoding signal Oscillator input pin No connection Oscillator output pin Backward output pin No connection No connection Forward output pin Positive power supply No connection Inverter 2 output pin for signal amplify Inverter 1 input pin for signa...
