HEF4538B-Q100 Datasheet Dual Precision Monostable Multivibrator

Manufacturer: Nexperia

Overview: HEF4538B-Q100 Dual precision monostable multivibrator Rev. 3 — 19 October 2018 Product data sheet 1.

General Description

The HEF4538B-Q100 is a dual retriggerable-resettable monostable multivibrator.

Each multivibrator has an active LOW trigger/retrigger input (nA), an active HIGH trigger/retrigger input (nB), an overriding active LOW direct reset input (nCD), an output (nQ) and its plement (nQ), and two pins (nREXT/CEXT, and nCEXT, always connected to ground) for connecting the external timing ponents CEXT and REXT.

Typical pulse width variation over the specified temperature range is ±0.2 %.
