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 out from quartz(-crystal) resonator with frequency Fc= 3,579545 ÌHz.
MAIN CHARACTERISTICS demodulates all 16 standard DTMF signals Low consume
