HEF4047BT,652

Multivibrators Overview

The HEF4047BT,652 is a retriggerable astable multivibrator from the Nexperia HEF4000B series, packaged in an SO14 (SOT108-1) plastic small outline package. 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 provides true and complemented buffered outputs and requires only one external resistor and capacitor for timing configuration. Static characteristics include a maximum supply current of 80 μA at 15 V. Dynamic propagation delays vary with load capacitance; typical values range from 22 ns to 130 ns depending on the specific input-to-output path and supply voltage.

Multivibrators Feature Summary

• Configurable as either a positive-edge or negative-edge triggered monostable multivibrator or a free-running astable multivibrator.
• Features retriggerable operation for pulse-width expansion and fast recovery time independent of pulse width.
• Includes clamp diodes on inputs to allow interfacing to voltages exceeding VCC using current limiting resistors.
• Provides ESD protection exceeding 2000 V (HBM Class 2) and 1000 V (CDM Class C3).

Multivibrators Applications

• Timing circuits requiring precise pulse width generation
• Frequency division and oscillator applications
• Retriggerable one-shot pulse generators

Multivibrators Procurement Notes

Verify the ordering suffix '652' against the manufacturer's latest documentation to confirm the specific tape-and-reel packaging format. Ensure the selected component matches the required SO14 package dimensions and lead finish specifications defined in the official datasheet before finalizing procurement orders.

Multivibrators Selection Notes

Select this component when a single IC solution is needed for both monostable and astable modes without external logic gates. Consider the low static power consumption and wide operating voltage range suitable for general-purpose CMOS logic applications. Verify that the external RC components meet the recommended leakage and resistance limits for accurate timing performance.

Multivibrators Part Context

This part belongs to the Nexperia HEF4000B series of high-speed CMOS logic devices. The HEF4047B family specifically addresses timing and waveform generation needs, offering flexibility through its dual-mode operation. It serves as a standard solution for designers requiring reliable oscillation or pulse generation in industrial and consumer electronics.

Multivibrators Replacement Considerations

Check for direct pin-compatible alternatives within the HEF4047B product line, such as the HEF4047BT,653, which may differ primarily in packaging quantity or reel specifications rather than electrical function.
