The MC14LC5447 is a silicon gate HCMOS IC designed to demodulate Bell
1
202 and V.23 1200–baud FSK asynchronous data. The primary application for
C. _{this device is in products that will be used to receive and display the calling}
IN _{number, or message waiting indicator sent to subscribers from participating}
R, _{central office facilities of the public switched network. The device also contains}
TO _{a carrier detect circuit and ring detector which may be used to power up the}
UC device.
ND Applications for this device include adjunct boxes, answering machines,
O _{feature phones, fax machines, and computer interface products.}
IC _{The MC14LC5447 offers the following performance features.}
SEM _{• Ring Detector On–Chip}
LE • Ring Detect Output for MCU Interrupt
CA • Power–Down Mode, Less than 1 µA
ES • Single Supply: + 3.5 to + 6.0 V
RE • Pin Selectable Clock Frequencies: 3.68 MHz, 3.58 MHz, or 455 kHz
Y ^F • Two Stage Power–Up for Power Management Control
B _{• Demodulates Bell 202 and V.23}
