CD4047BE

• Lower power consumption: special CMOS oscillator configuration
• Monostable (one-shot) or astable (free-running) operation
• True and complemented buffered outputs
• Only one external R anc C required
• Buffered inputs
• 100% tested for quiescent current at 20 V
• Standardized, symmetrical output characteristics
• 5-V, 10-V, and 15-V parametric ratings
• Meets all requirements of JEDEC Tentative Standard No. 13B, "Standard Specifications for Description of 'B' Series CMOS Devices"
• Monostable Multivibrator Features:
  • Positive-or negative-edge trigger
  • Output pulse width independent of trigger pulse duration
  • Retriggerable option for pulse width expansion
  • Internal power-on reset circuit
  • Long pulse widths possible using small RC components by means of external counter provision
  • Fast recovery time essentially independent of pulse width
  • Pulse-width accuracy maintained at duty cycles approaching 100%
• Astable Multivibrator Features:
  • Free-running or gatable operating modes
  • 50% duty cycle
  • Oscillator output available
  • Good astable frequency stability:
    
    Frequency deviation:
    
    = ±2% + 0.03%/°C @ 100 kHz
    
    = ±0.5% +0.015%/°C @ 10 kHz (circuits "trimmed" to frequency V_DD= 10 V ± 10%)
• Applications:
  
  Digital equipment where low-power dissipation and/or high noise immunity are primary design requirements:
  • Envelope detection
  • Frequency multiplication
  • Frequency division
  • Frequency discriminators
  • Timing circuits
  • Time-delay applications
