MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC14LC5447/D Product Preview Calling Line Identification (CLID) Receiver with Ring Detector The MC14LC5447 is a silicon gate HCMOS IC designed to demodulate Bell 202 and V.23 1200–baud FSK asynchronous data. The primary application for this device is in products that will be used to receive and display the calling number, or message waiting indicator sent to subscribers from participating central office facilities of the public switched network. The device also contains a carrier detect circuit and ring detector which may be used to power up the device. Applications for this device include adjunct boxes, answering machines, feature phones, fax machines, and computer interface products. The MC14LC5447 offers the following performance features. Ring Detector On–Chip Ring Detect Output for MCU Interrupt Power–Down Mode, Less than 1 µA Single Supply: + 3.5 to + 6.0 V Pin Selectable Clock Frequencies: 3.68 MHz, 3.58 MHz, or 455 kHz Two Stage Power–Up for Power Management Control Demodulates Bell 202 and V.23 MC14LC5447 16 1 P SUFFIX PLASTIC DIP CASE 648 16 1 DW SUFFIX SOG PACKAGE CASE 751G ORDERING INFORMATION MC14LC5447P MC14LC5447DW Plastic DIP SOG Package PIN ASSIGNMENT TI RI RDI1 RDI2 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VDD DOC DOR CDO RDO CLKSIN OSCin OSCout BLOCK DIAGRAM 1 2 NC RT PWRUP TIP RING – + BPF DEMOD VAG 14 15 DOR DOC CDO VSS NC = NO CONNECTION RDI1 RDI2 RT 3 4 6 RING ...
