Product Summary

The LMC567CN is a low power general purpose LMCMOS tone decoder which is functionally similar to the industry standard LM567. It consists of a twice frequency voltage-controlled oscillator (VCO) and quadrature dividers which establish the reference signals for phase and amplitude detectors.

Parametrics

LMC567CN absolute maximum ratings: (1)Input Voltage, Pin 3: 2 Vp–p; (2)Supply Voltage, Pin 4: 10V; (3)Output Voltage, Pin 8: 13V; (4)Voltage at All Other Pins: Vs to Gnd; (5)Output Current, Pin 8: 30 mA; (6)Package Dissipation: 500 mW; (7)Operating Temperature Range (TA): -25℃ to +125℃; (8)Storage Temperature Range: -55℃ to +150℃.

Features

LMC567CN features: (1)Functionally similar to LM567; (2)2V to 9V supply voltage range; (3)Low supply current drain; (4)No increase in current with output activated; (5)Operates to 500 kHz input frequency; (6)High oscillator stability; (7)Ground-referenced input; (8)Hysteresis added to amplitude comparator; (9)Out-of-band signals and noise rejected; (10)20 mA output current capability.
