HEF4047B
Datasheet
General 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).
Features
- Direct interface to C-MOS, TTL, etc.
- High-speed switching
- No secondary breakdown.
