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 (V
CC
=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
