MENOTS Order this document MOTOROLA by MC145436/D m= SEMICONDUCTOR [= TECHNICAL DATA Dual Tone Multiple Frequency Receiver _— The MC145436 is a silicon gate CMOS LSI device containing the filter and i Say mY P SUFFIX decoder for detection of a pair of tones conforming to the DTMF standard with 4 PLASTIC outputs in hexadecimal. Switched capacitor filter technology is used together with 1 CASE 646 digital circuitry for the timing control and output circuits. The MC145436 provides excellent power line noise and dial tone rejection and is suitable for applications in central office equipment, PABX, and keyphone systems, remote control — DW SUFFIX equipment and consumer telephony products. SOG The MC145436 offers the following performance features: 1 CASE 751G Single +5 V Power Supply © Detects All 16 Standard Digits © Uses Inexpensive 3.58-MHz Crystal PIN ASSIGNMENTS Provides Guard Time Controls to Improve Speech Immunity PLASTIC © Output in 4-Bit Hexadecimal Code d h © Built-in 60 Hz and Dial Tone Rejection bat te 147 D4 © MC145436P Pin Compatible with SSI-204 ore 13 f} DB ene (| 3 12) ov Voo 4 110 ate at qs 10D Xin Xen 6 9D Xout @ Ain 7 8 0 GND SOG BLOCK DIAGRAM o2Q 160° 16 1) D4 pig2 15) 08 enB 3 140 pv Ain [60 Hz Oo’ Vpp U4 13] Nc REJECTION [8s | GT vcs 12] ATB FILTER TIMING + { ase | ° CIRCUIT etd é 111) Xin = ? ov Xen 0 7 10 D Xout Ex " .
