Hysteresis regulator (Regulator circuit has built-in hysteresis to prevent false triggering and rotary dial “Chirps”) PIN ASSIGNMENT

VCC 1 Positive power supply. RE 2 Initiation of oscillation start input LFI 3 Low frequency oscillator input LF0 4 Low frequency oscillator output GND 5 Negative power supply HF0 6 High frequency oscillator output HFI 7 High frequency oscillator input OUT 8 Tone output MAXIMUM RATINGS* Symbol Parameter Value Unit VCC DC Supply Voltage (Referenced to GND) to +30.0 V PD Power Dissipation in Still Air, Plastic DIP 400 mW Tstg Storage Temperature -65 to +150 °C * Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the Recommended Operating Conditions. RECOMMENDED OPERATING CONDITIONS Symbol Parameter Min Max Unit VCC DC Supply Voltage (Referenced to GND) 13.0 29.0 V TA Operating Temperature -45 +65 °C This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions m ust be taken to avoid applications of any voltage highe r than maximum rated voltages to this high-impedance ci rcuit. For proper operat ion, V IN and V OUT should be const rained t o t he range GND ≤(VIN or VOUT)≤VCC. Unused inputs must always be t ied to an appropri ate logic voltage level (e.g., ei ther GND or VCC). Unused outputs must be left open.

Initiation supply voltage (VSI) is the supply voltage required to start the tone ringer oscillating. 2. Sustaining voltage (VSUS) is the supply voltage required to maintain oscillation. 3. VTR and ITR are the conditions applied to trigger in to start oscillation for VSUS≤VCC≤VSI. 4. VDIS and IDIS are the conditions applied to trigger in to inhibit oscillation for VSI≤VCC. 5. Trigger current must be limited to this value externally.
