General Description
The RTS715-3 is a CMOS LSI designed to function as transmitters.
The RTS715-3
provides seven functions and can combine with RTS510B and RTS511B. As a infrared
remote controller, each data input has a corresponding output signal code, and for the
convenience, users can define a decoder to decode the signal to meet different
applications.
