SCTX2B/SDRX2BD (NO：S&CIC0515)
FIVE FUNCTIONS REMOTE CONTROLLER
Features
Wide operating SCTX2B voltage range: 2.4V to 12V
SCTX2B very low stand-by current
Few external components needed
SDRX2BD built- in 3.8v zener
General Description
The SCTX2B/RX2BD are a pair of CMOS LSIs designed for remote controlled car applications. The
SCTX2B/RX2BD have five control keys controlling the motions ( i.e. forward, backward, rightward,
leftward, and the turbo function ) of the remote controlled car.
Absolute Maximum Ratings
DC Supply Voltage-----------------------------0.3V to 5.0V
Input/Output Voltage---------------------------GND –0.2V to VDD+0.2V
Operating temperature------------------------- -10℃ to 60℃
Storage Temperature---------------- -25℃ to 125℃
Comment*
Never allow a stress the values listed under “Absolute Maximum Ratings”, otherwise the device would
suffer from a permanent damage. Nor is a stress at the listed value be allowed 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.
Oscillation Frequency
SCTX2B VDD=3.0V，Rosc=250K，Fosc=110KHz~130KHz。
SDRX2BD VDD=3.8V，Rosc=220K，Fosc=110KHz~130KHz。
