HEF4528B-Q100 Dual monostable multivibrator Rev. 1 14 March 2017 Product data sheet 1 General description The HEF4528B-Q100 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 (C ) must be connected between nCEXT and EXT nREXT/CEXT and an external resistor (R ) must be connected between nREXT/CEXT EXT and V . The output pulse duration is determined by the external timing components DD C and R . A HIGH-to-LOW transition on nA when nB is LOW or a LOW-to-HIGH EXT EXT transition on nB when nA is HIGH produces a positive pulse (LOW-HIGH-LOW) on nQ and a negative pulse (HIGH-LOW-HIGH) on nQ if the nCD is HIGH. A LOW on nCD forces nQ LOW, nQ HIGH and inhibits any further pulses until nCD is HIGH. It operates over a recommended V power supply range of 3 V to 15 V referenced to DD V (usually ground). Unused inputs must be connected to V , V , or another input.
