CD4047BM Datasheet PDF - TI

●The CD4047BM is a low-power CMOS 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. The 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. The true input pulses on the ASTABLE input or complement pulses on the ASTABLE\ input allow the circuit to be used as a gatable multivibrator.
