HEF4047BT,653

Multivibrators Overview

The HEF4047BT,653 is a retriggerable astable multivibrator from the Nexperia HEF4000 series, housed in an SO14 (SOT108-1) package. It operates on a supply voltage of 3 V to 15 V with a maximum supply current of 80 µA at 15 V. The device supports positive or negative edge-triggered monostable operation and free-running or gatable astable modes. Propagation delays range from 22 ns to 320 ns depending on load capacitance and supply voltage. Outputs include true and complement buffered signals plus an oscillator output.

Multivibrators Feature Summary

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

Multivibrators Applications

• Timing circuits requiring precise pulse width generation
• Frequency division and clock generation systems
• Pulse width expansion applications via retriggering mode
• Gated oscillator implementations

Multivibrators Procurement Notes

Verify the ordering suffix matches the required package variant. Confirm RoHS compliance status for specific manufacturing lots. Ensure design accounts for the specified operating temperature range of -40 °C to +85 °C. Check that external timing components meet leakage and resistance recommendations for accuracy.

Multivibrators Selection Notes

Select this component when a single IC must provide both monostable and astable functionality. The inclusion of an oscillator output facilitates frequency division tasks. Verify that the external RC network values comply with the recommended ranges to maintain timing accuracy. Consider the propagation delay variations relative to the specific supply voltage and load conditions.
