HEF4047BP,652

Multivibrators Overview

The HEF4047BP,652 is a monostable/astable multivibrator from the Nexperia HEF4047B series. It operates within a supply voltage range of 3 V to 15 V and supports an ambient temperature range of -40 °C to +85 °C. The device features true and complemented buffered outputs (O and O) along with an oscillator output. Timing parameters are determined by external components Rt and Ct connected to pins 2, 3, and 1. Propagation delays vary based on load capacitance; for example, at 15 V, typical HIGH-to-LOW propagation delay ranges from 22 ns to 60 ns depending on CL.

Multivibrators Feature Summary

• Configurable as either a retriggerable astable multivibrator or positive/negative-edge triggered monostable multivibrator.
• Provides true and complemented buffered outputs alongside a dedicated oscillator output pin.
• Includes input clamp diodes allowing interface to voltages exceeding VCC using current limiting resistors.
• Features ESD protection exceeding 2000 V (HBM Class 2) and 1000 V (CDM Class C3).

Multivibrators Applications

• Timing circuits requiring precise pulse width generation via external RC components.
• Frequency division applications utilizing the oscillator output.
• Retriggerable pulse expansion systems where input pulse periods are shorter than the programmed timing period.

Multivibrators Procurement Notes

Verify the ordering suffix matches the required package type. The 'BP' designation indicates a specific packaging variant distinct from other available options like 'BT'. Confirm that the component meets the specified operating temperature range and voltage limits for your application environment before finalizing procurement.

Multivibrators Selection Notes

Select this component when a single IC must support both astable and monostable modes with minimal external parts. Ensure the design accommodates the required external resistor and capacitor values for accurate timing. Consider the propagation delay variations relative to load capacitance and supply voltage when designing high-speed logic interfaces.

Multivibrators Part Context

This part belongs to the HEF4047B family of monostable/astable multivibrators manufactured by Nexperia. It shares functional characteristics with other devices in the series but differs in physical packaging.
