HEF4047B - NXP

HEF4047B Monostable/astable multivibrator

The HEF4047B consists of a gatable astable multivibrator incorporating logic techniques 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 mod.

Features
