LM567 LM567C Tone Decoder February 1995 LM567 LM567C Tone Decoder General Description The LM567 and LM567C are general purpose tone decoders designed to provide a saturated transistor switch to ground when an input signal is present within the passband The circuit consists of an I and Q detector driven by a voltage controlled oscillator which determines the center frequency of the decoder External components are used to independently set center frequency bandwidth and output delay Y Y Y Y Y Bandwidth adjustable from 0 to 14% High rejection of out of band signals and noise Immunity to false signals Highly stable center frequency Center frequency adjustable from 0 01 Hz to 500 kHz Applications Y Y Y Features Y Y Y Y Y Y 20 to 1 frequency range with an external resistor Logic compatible output with 100 mA current sinking capability Touch tone decoding Precision oscillator Frequency monitoring and control Wide band FSK demodulation Ultrasonic controls Carrier current remote controls Communications paging decoders Connection Diagrams Metal Can Package Dual-In-Line and Small Outline Packages TL H 6975 ­ 1 Top View Order Number LM567H or LM567CH See NS Package Number H08C Top View Order Number LM567CM See NS Package Number M08A Order Number LM567CN See NS Package Number N08E TL H 6975 ­ 2 C1995 National Semiconductor Corporation TL H 6975 RRD-B30M115 Printed in U S A Absolute Maximum Ratings If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage Pin Power Dissipation (Note 1) V8 V3 V3 Storage Temperature Range Operating Temperature Range LM567H LM567CH LM567CM LM567CN 9V 1100 mW 15V b 10V V4 a 0 5V b 65 C to a 150 C b 55 C to a 125 C 0 C to a 70 C Soldering Information Dual-In-Line Package Soldering (10 sec ) Small Outline Package Vapor Phase (60 sec ) Infrared (15 sec ) 260 C 215 C 220 C See AN-450 ``Surface Mounting Methods and Their Effect on Product Reliability'' for other methods of soldering surface mount devices Electrical Characteristics AC Test Circuit Parameters Power Supply Voltage Range Power Supply Current Quiescent Power Supply Current Activated Input Resistance Smallest Detectable Input Voltage Largest No Output Input Voltage Largest Simultaneous Outband Signal to Inband Signal Ratio Minimum Input Signal to Wideband Noise Ratio Largest Detection Bandwidth Largest Detection Bandwidth Skew Largest Detection Bandwidth Variation with Temperature Largest Detection Bandwidth Variation with 4 75 b 6 75V Supply Voltage Highest Center Frequency Center Frequency Stability (4 75­5 75V) Bn e 140 kHz RL e 20k RL e 20k TA e 25 C V a e 5V LM567 Min 4 75 Typ 50 6 11 18 20 20 10 15 6 b6 Conditions LM567C LM567CM Max 90 8 13 15 25 10 Min 4 75 Typ 50 7 12 20 20 15 6 b6 Units V mA mA kX Max 90 10 15 IL e 100 mA fi e fo IC e 100 mA fi e fo 25 mVrms mVrms dB dB 12 14 1 g0 1 g1 16 2 10 14 2 g0 1 18 3 % of fo % o
