CD4047BE Astable/Monostable Multivibrator IC DIP-14 Package

CD4047 consists of a getable astable multivibrator 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, an 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 getable multivibrator. The OSCILLATOR output period will be half of the Q terminal output in the astable mode. However, a 50% duty cycle is not guaranteed at this output.

The CD4047 triggers in the monostable mode when a positive-going edge occurs on the +TRIGGER-input while the -TRIGGER is held low. Input pulses may be of any duration relative to the output pulse.

The CD4047-Series types are supplied in 14-lead hermetic dual-in-line ceramic packages (F3A suffix), 14-lead dual-in-line plastic packages (E suffix), 14-lead small-outline packages (M, MT, M96, and NSR suffixes), and 14-lead thin shrink small-outline packages (PW and PWR suffixes).

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

- Pulse-width accuracy maintained at duty cycles approaching 100%
Astable Multivibrator Features:
- Free-running or getable 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
