CAUTIONS
Combined characteristics µPC9903 µPD7073 µPD9903 designed used combination with µPC7073. Therefore, first half electrical specifications described below ratings µPD9903 discrete unit while second half combined ratings with µPC7073. Subscriber circuit constants that determined factors such termination impedance configured enable setting external order parameters. Consequently, input order that suitable target impedance result failure obtain required characteristics. Absolute maximum ratings Application voltage current excess absolute maximum ratings result damage. especially cautious about surges, etc. Load by-pass capacitor Because PC7073 PD9903 several internal high-frequency operational amplifiers, high power supply impedance cause instability these internal operational amplifiers (such oscillation). suppress such instability eliminate power supply noise, connect by-pass capacitors ACOM approximate having superior high frequency characteristics close possible PC7073's power supply pins PD9903's power supply pins (AVDD DD). Addition ACOM connection capacitor voltage ACOM between PC7073 PD9903 reference voltage signal source between PC9903 PC7073. Superposing noise this have adverse effects transmission characteristics. Therefore, make wires between ACOM pins LSIs short possible, connect capacitors ACOM approximate having superior high frequency characteristics close possible pins.

NOTES CMOS DEVICES
PRECAUTION AGAINST SEMICONDUCTORS
Note: Strong electric field, when exposed device, cause destruction gate oxide ultimately degrade device operation. Steps must taken stop generation static electricity much possible, quickly dissipate once, when occurred. Environmental control must adequate. When dry, humidifier should used. recommended avoid using insulators that easily build static electricity. Semiconductor devices must stored transported anti-static container, static shielding conductive material. test measurement tools including work bench floor should grounded. operator should grounded using wrist strap. Semiconductor devices must touched with bare hands. Similar precautions need taken boards with semiconductor devices
HANDLING UNUSED INPUT PINS CMOS
Note: connection CMOS device inputs cause malfunction. connection provided input pins, possible that internal input level generated noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar NMOS devices. Input levels CMOS devices must fixed high using pull-up pull-down circuitry. Each unused should connected with resistor, considered have possibility being output pin. handling related unused pins must judged device device related specifications governing devices.
STATUS BEFORE INITIALIZATION DEVICES
Note: Power-on does necessarily define initial status device. Production process does define initial operation status device. Immediately after power source turned devices with reset function have been initialized. Hence, power-on does guarantee out-pin levels, settings contents registers. Device initialized until reset signal received. Reset operation must executed immediately after power-on devices having reset function.
