HEF4538B Datasheet Dual Precision Monostable Multivibrator

Manufacturer: NXP Semiconductors

Overview: HEF4538B Dual precision monostable multivibrator Rev. 10 — 1 April 2016 Product data sheet 1.

General Description

The HEF4538B 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 complement (nQ), and two pins (nREXT/CEXT, and nCEXT, always connected to ground) for connecting the external timing components CEXT and REXT.

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

Key Features

  • Tolerant of slow trigger rise and fall times.
  • Fully static operation.
  • 5 V, 10 V, and 15 V parametric ratings.
  • Standardized symmetrical output characteristics.
  • Specified from 40 C to +85 C and 40 C to +125 C.
  • Complies with JEDEC standard JESD 13-B 3. Ordering information Table 1. Ordering information All types operate from 40 C to +125 C. Type number Package Name.
