Product Overview

The CD4047BE is a CMOS low-power Mono-stable/Astable Multi-vibrator with logic techniques incorporated to permit positive or negative edge-triggered monostable multivibrator action with retriggering and external counting options. Inputs include +TRIGGER, -TRIGGER, ASTABLE, ASTABLE\, RETRIGGER and EXTERNAL RESET. Buffered outputs are Q\, Q and OSCILLATOR. In all modes of operation and external capacitor must be connected between C-Timing and RC-Common terminal and an external resistor must be connected between the R-Timing and RC-Common terminals. Astable operation is enabled by a high level on the STABLE input or a low level on the ASTABLE\ input or both. The period of the square wave at the Q and Q\ Outputs in this mode off operation is a function of the external components employed. "True" input pulses on the ASTABLE input or "Complement" pulses on the ASTABLE\ input allow the circuit to be used as a gatable multivibrator.
  • Lower power consumption special CMOS oscillator configuration
  • Monostable (one-shot) or astable (free-running) operation
  • True and complemented buffered outputs
  • Only one external R and C required
  • Buffered inputs
  • 100% Tested for quiescent current at 20V
  • Standardized, symmetrical output characteristics
  • 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%
