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.
