TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC The TA7343AP is PLL FM stereo multiplex IC. It is suitable for automotive applications and portable radio applications because of space merit by the package ——-- and wide supply voltage range. eae FEATURES Ty | Y | | t Ht @ Excellent stereo LED sensitivity \\| | u : VL(ON) =9MVrms (Typ-) © Suitable for LED drivin tI =20mA (Max. 9 LED (Max.) SIP9-P-2.54A @ Recommendable input voltage range Weight : 0.92g (Typ.) : Vin = 200~700MVrms @ Operating supply voltage range : Vcc =3.5~12V @ Excellent channel separation through entire audio frequency range : Sep =45dB (Typ.) @ Low distortion : THD =0.08% (Typ.) at Vin =200MVrms (Stereo) @ Built-in compulsive monaural function. (The VCO is stopped when the pin® is connected with the power supply line, and then the stereo indicator is turn off.) @ Easy adjustment (The monitored free running frequency of VCO is 38kHz at pin®.) 961001EBA2 ©@ TOSHIBA is continually working to improve the quality and the reliability of its products, Nevertheless, semiconductor devices in general can malfunction or ‘all due to their inherent electrical sensivty and vulnerability to physical stress. ts the responsibilty of the buyer, when tiizing TOSHIBA products, to observe standards of safety, and to avoid situations in which a malfunction or failure of a TOSHIBA product could cause loss of human life, bodily injury or damage to property.
