FEATURES
GENERAL DESCRIPTION
SM5032C/D is an infrared remote control
decoder utilizing COMOS technology, paired
with SM5021 for transmitter. The remote
control system is capable of controlling eight
functions and CP1 to CP6 can multi-decode.
There is an option for two toggle signal
outputs in these data control functions.
* Wide operation voltage range, 2.4V to 6V
* Infrared remote control receiver
* Two custom code to separate products
* Eight control functions for continuous signal
* Mulit-key control outputs
* Two toggle signal can be optioned in outputs
Also there are two custom codes for user to
separate different products.
* A single terminal type oscillator by means of
RC is provided
* Low power consumption
* High noise immunity
APPLICATIONS
* 14 pin DIP or SO package
* Consumer Products Remote Control
* Toy Remote Control
* Audio Remote Control
