IL9270N - ETC

IL9270N DTMF signal receiver

IL9270N DTMF signal receiver (analog HM9270) IC IL9270N is (DTMF) signal two-channel receiver-decoder (code 2 from 8).IÑ is fabricated on CÌÎS technology and containes bandpass filters on switched capacitors. IC checks length of incoming twochannel signal dispatches and pauses between them. Information output as 4-digit binary code.IC clocking is carried ou.
