DESCRIPTION

The HEF4047B 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 MR (Master Reset).

Buffered outputs are O, O and OSCILLATOR OUTPUT. In all modes of operation an external capacitor (Ct) must be connected between CTC and RCTC, and an external resistor (Rt) must be connected between RTC and RCTC (continued on next page).

Astable operation is enabled by a HIGH level on the ASTABLE input. The period of the square wave at O and O outputs is a function of the external components employed. ‘True’ input pulses on the ASTABLE or ‘complement’ pulses on the ASTABLE input, allow the circuit to be used as a gatable multivibrator. The OSCILLATOR OUTPUT period will be half of the O output in the astable mode. However, a 50 duty factor is not guaranteed at this output.

In the monostable mode, positive edge-triggering is accomplished by applying a leading-edge pulse to the + TRIGGER input and a LOW level to the ? TRIGGER input. For negative edge-triggering, a trailing-edge pulse is applied to the ? TRIGGER and a HIGH level to the + TRIGGER. Input pulses may be of any duration relative to the output pulse. The multivibrator can be retriggered (on the leading-edge only) by applying a common pulse to both the RETRIGGER and + TRIGGER inputs. In this mode the output pulse remains HIGH as long as the input pulse period is shorter than the period determined by the RC components.
