HEF4047BT-Q100J

Multivibrators Overview

The HEF4047BT-Q100J is a retriggerable astable multivibrator from Nexperia, qualified to AEC-Q100 Grade 3 for automotive applications. It operates within a supply voltage range of 3 V to 15 V and an ambient temperature range of -40 °C to +85 °C. The device supports positive- or negative-edge triggered monostable operation and free-running or gatable astable modes. Timing is set by external components Rt and Ct connected to pins 2, 3, and 1. It features buffered true and complemented outputs (pins 10 and 11) and an oscillator output (pin 13).

Multivibrators Feature Summary

• Supports both monostable one-shot and astable free-running configurations with single external resistor and capacitor.
• Provides true and complemented buffered outputs alongside a dedicated oscillator output pin.
• Includes input clamp diodes allowing interface to voltages exceeding the supply rail using current limiting resistors.
• Features ESD protection exceeding 2000 V (HBM Class 2) and 1000 V (CDM Class C3).

Multivibrators Applications

• Retriggerable pulse width expansion circuits
• Gatable multivibrator designs
• Timing circuits utilizing external counter provisions

Multivibrators Procurement Notes

Verify the specific suffix 'Q100' confirms AEC-Q100 Grade 3 qualification and the '-40 °C to +85 °C' operating range. Ensure the SO14 package (SOT108-1) matches the PCB footprint. Confirm that the ordering information aligns with the requested temperature grade and packaging format before finalizing procurement.

Multivibrators Selection Notes

Select this component when automotive-grade reliability is required for timing applications. It is suitable for designs needing edge-triggered monostable action or gated astable oscillation. Consider the external RC component limitations and the need for non-polarized capacitors with low leakage to maintain timing accuracy across the specified voltage and temperature ranges.
