TX2/RX2
REMOTE CONTROLLER WITH FIVE FUNCTIONS
General Description
The TX2/RX2 are a pair of CMOS LSIs designed for remote controlled car applications. TX2
Is the transmitter and RX2 is the receiver. They provide five function key to control forward, Backward,
Rightward, Leftward and Turbo motions. Beside,a combination of these five motions can be played.
RX2 Provide two high effective amplifiers and Enhance Signal Input recognition capacity to enhance remote
control distance.
Major Core Features:
! Wide and low operating voltage range: 2.2V to 5.0V
! Typical oscillator frequency:
RF:128KHz.
IR :114KHz(Carrier Frequency:57KHz).
IR : 76KHz(Carrier Frequency:38KHz).
! Provide two transmissive interface(RF and IR)for different application.
! RX2 Provide two high effective amplifiers to enhance remote control distance.
! Enhance Signal Input recognition capacity for very weak signal.
! Auto Power-OFF function for TX2
! Low Standby current (TX2) and low operating current.(RX2).
! Oscillator with an external resistor.
Peripheral Features:
! 5-function remote controller controlling forward/ backward/ turbo/ right/ left.
! Few external components needed.
Application Field:
! remote controlled toy.
! remote electric appliance controller.

TX2/RX2
Special Features Description:
! TX2 auto Power OFF function:
When input key is pulled low, TX2 will wake up, SC and SO will continuously send out code
in RF format (Non-Carrier) and IR format(Carrier). However when a complete code is sent out
and the key is released,TX2 will automatically into powered off mode.
! TX2 IR transmission interface:
Built-in counter to generate 38KHz or 57KHz carrier frequency for Infrared applications.

Absolute Maximum Ratings
DC Supply Voltage.....................................0.3V to 5.0V
Input/Output Voltage...........GND -0.2V to VDD + 0.2V
Operating temperature..............................-10°C to 60°C
Storage Temperature..............................-25°C to 125°C
Comments*
Never allow a stress to exceed the values listed under
"Absolute Maximun Ratings", otherwise the device would
suffer from a permanent damage. Nor is a stress at the listed
value be allowed to persist over a period, since an extended
exposure to the absolute maximum rating condition may
also affect the reliability of the device, if not causing a
damage thereof.
