The UM3750 Encoder / Decoder is a CMOS / LSI digital code Transmitter-Receiver system. Working in the transmit(encoder) mode, the UM3750 will sequentially encode and transmit 12 bits of input. Each of the 12 bits may be 1 or 0 to allow 4096 different codes.
1. Single chip contains both Encoder and Decoder. 2. 3V to 11 V operation. 3. On chip oscillator uses non-critical RC components
OB3302 is a cost effective PWM controller that dedicated for CCFL inverter application in push pull topology, it integrates complete functions which includes striking management, dimming control and lamp fail protections.
