HEF4528B Datasheet Dual Monostable Multivibrator

Manufacturer: Nexperia

Overview: HEF4528B Dual monostable multivibrator Rev. 11 — 4 March 2022 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 plement (nQ), and two external timing ponent 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.
