HEF4047BT

Monostable/astable multivibrator

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 components (Rt and Ct). Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Features and benefits

General

  • Monostable (one-shot) or astable (free-running) operation

  • True and complemented buffered outputs

  • Only one external resistor and capacitor required

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 recovery time independent of pulse width

  • Pulse-width accuracy maintained at duty cycles approaching 100%

Astable multivibrator

  • Free-running or gatable operating modes

  • 50% duty cycle

  • Oscillator output available

Sample

As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: https://extranet.nexperia.com.

Sample orders normally take 2-4 days for delivery.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
