74HC4538DB Datasheet Dual Retriggerable Precision Monostable Multivibrator

Manufacturer: Nexperia

Overview: 74HC4538 Dual retriggerable precision monostable multivibrator Rev.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The 74HC4538 is a dual retriggerable-resettable monostable multivibrator.

Each multivibrator has two trigger/retrigger inputs (nA and nB), a direct reset input (nCD), two complementary outputs (nQ and nQ), and two pins (nREXT/CEXT and nCEXT) for connecting the external timing components CEXT and REXT.

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