OUTLINE & DIMENSIONS
Both outputs enabled Both outputs are disabled when control pad is taken below 0.3V referenced to ground. Oscillator is always 'on'. (Special request oscillator is off when disabled.) Enable: Both Outputs are enabled when control pad is taken above 0.7 Vcc referenced to ground. ABSOLUTE MAXIMUM RATINGS (Permanent damage may be caused if operated beyond these limits.) Supply Voltage Vdd: +4.6V max. Input Voltage Vi: Vss -0.5 min., VDD +0.5V max. Input Voltage Vo: Vss -0.5 min., Vdd +0.5V max.
