The HEF4528B is a dual retriggerable-resetable monostable multivibrator. Each multivibrator hasan active LOW input (nA), and active HIGH input (nB), an active LOW clear direct input (nCD), anoutput (nQ) and its complement (nQ), and two external timing component connecting pins (nCEXT,always connected to ground, and nREXT/CEXT).An external timing capacitor (CEXT) must be connected between nCEXT and nREXT/CEXT andan external resistor (REXT) must be connected between nREXT/CEXT and VDD. The outputpulse duration is determined by the external timing components CEXT and REXT. A HIGH-to-LOWtransition on nA when nB is LOW or a LOW-to-HIGH transition on nB when nA is HIGH producesa positive pulse (LOW-HIGH-LOW) on nQ and a negative pulse (HIGH-LOW-HIGH) on nQ if thenCD is HIGH. A LOW on nCD forces nQ LOW, nQ HIGH and inhibits any further pulses until nCDis HIGH.It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usuallyground). Unused inputs must be connected to VDD, VSS, or another input.
