HEF4047B Datasheet Monostable/astable Multivibrator

Manufacturer: Nexperia

Overview: HEF4047B Monostable/astable multivibrator Rev. 6 — 17 March 2017 Product data sheet 1.

General Description

The HEF4047B is a retriggerable astable multivibrator that can be configured as either a positive-edge or negative-edge triggered monostable multivibrator.

The output pulse width is programmed by selection of external ponents (Rt and Ct).

Inputs include clamp diodes.

Key Features

  • 2.1 General.
  • Monostable (one-shot) or astable (free-running) operation.
  • True and complemented buffered outputs.
  • Only one external resistor and capacitor required 2.2 Monostable multivibrator.
  • Positive- or negative-edge triggering.
  • Output pulse width independent of trigger pulse duration.
  • Retriggerable option for pulse-width expansion.
  • Long pulse width possible using small RC components with external counter provision.
  • Fast.
