Embeddinator DTMF DECODER MODULE WITH 4-BIT OUTPUT Electronic Components Electronic Hobby Kit

EnGeniusLab Introduces compact and highly readable DTMF Module stands out in the league of similar modules available in the electronics markets provide operates 5 to 9 V DC. It’s equally capable to both CDMA AND GSM handsets works fine with stereo/MONO. Every single data bit is provided with an on this board led indicator for quick visual confirmation. The momentary output LED bit is also provided with a bright white flash LED. When a valid DTMF tone is received as input the status led flashes and the corresponding 4 bit binary value is latched to the output pins D0, D1, D2 & D3 and then a status led blink. The module is capable of providing 16 different outputs if the tones are fade thru a tone generation circuit or through PC based software ( the inputs being from 0-9 * # and A B C D ). Decodes DTMF audio signal to 4 bit binary TTL level output with LED indication. Suitable for use with microcontroller applications.However when operated through cellular phone device it can provide only 12 diff outputs because of 0-9 keyboard along with * and #. Special Features:- •Decodes DTMF as 4 bit binary •TTL level output for direct connection to microcontrollers •Low power 5V DC operation & Operating Current 100 mA •LED indication of outputs •Simple to use •Based on excellent HT92B70 IC
