Product Summary

The NE567N is a kind of tone and frequency decoder. It is a highly stable phase-locked loop with synchronous AM lock detection and power output circuitry. Its primary function is to drive a load whenever a sustained frequency within its detection band is present at the self-biased input. The bandwidth center frequency and output delay are independently determined by means of four external components. The typical applications include: (1)Touch-Tone[ decoding; (2)Carrier current remote controls; (3)Ultrasonic controls (remote TV, etc.); (4)Communications paging.

Parametrics

Absolute maximum ratings: (1)TA, Operating temperature: 0 to +70 ℃; (2)VCC, Operating voltage: 10 V; (3)V+, Positive voltage at input: 0.5 +VS V; (4)V-, Negative voltage at input: -10 VDC; (5)VOUT, Output voltage (collector of output transistor): 15 VDC; (6)TSTG, Storage temperature range: -65 to +150 ℃; (7)PD, Power dissipation: 300 mW.

Features

Features: (1)Wide frequency range (.01Hz to 500kHz); (2)High stability of center frequency; (3)Independently controllable bandwidth (up to 14%); (4)High out-band signal and noise rejection; (5)Logic-compatible output with 100mA current sinking capability; (6)Inherent immunity to false signals; (7)Frequency adjustment over a 20-to-1 range with an external resistor; (8)Military processing available.
