Manufacturer: NXP Semiconductors

Overview: 74HC4538; 74HCT4538 Dual retriggerable precision monostable multivibrator Rev. 4 — 24 February 2016 Product data sheet 1.

General Description

The 74HC4538;

74HCT4538 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.
