RX-3  
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.  
FEATURES  
* Wide operating voltage range (VCC=2.2 ~ 12V)  
* Few external components are needed  
* Typical oscillator frequency 76KHz  
* RX-3 built-in Zener 3V  
DIP-16  
* 2 functions remote controller including forward/backward
