HEF4528B Dual monostable multivibrator Rev. 7 — 22 November 2011 Product data sheet 1. General description The HEF4528B is a dual retriggerable-resetable monostable multivibrator. Each multivibrator has an active LOW input (nA), and active HIGH input (nB), an active LOW clear direct input (nCD), an output (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 and an external resistor (REXT) must be connected between nREXT/CEXT and VDD. The output pulse duration is determined by the external timing components CEXT and REXT.
