The CD4047B IC consists of a gatable 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, 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.

Features of CD4047 Dual JK Master-Slave Flip-Flop:

• 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 20 V.
• Standardized, symmetrical output characteristics.
• 5-V, 10-V, and 15-V parametric ratings.

Applications of CD4047 Dual JK Master-Slave Flip-Flop:

• Envelope detection.
• Frequency multiplication.
