Hi All: I been try to find a supplier for the TX2C And RX2C ICs. These are R/C toy car remote controller integrated chips. they are used in R/C cars brand names like nikko, radio shack, Bright lite , ect ect.. also been try to find there datasheets. does anybody know a website where i could get the TX2C and RX2C Datasheets. (Second Question). The TX2C chip thats in the r/c transmitter controller on pin-12osci and on pin-11osco I like to know the internal oscillator is set with a 200k ohm resistor and why they used 200k resistor and not a high or low resistor can you explain this to me that i could understand it. I can't post the circuit at this time. BUT you can see it at this site www.elenco.com/manuals/rcc-7k.pdf.. Can anybody who knows about R/C Electronics HELP ME. THANK YOU . Any help would be very Apprecited... :-[
