Frequently Asked Questions
What are the operating modes and output characteristics of the Nexperia HEF4047BT?
The HEF4047BT provides both monostable and astable multivibrator modes with retriggerable capability and gating functions. The 14-pin package includes complementary output drivers operating at frequencies from DC to 5 MHz depending on external RC time constants, supporting supply voltages from 3 V to 15 V with typical supply current of 50 µA in astable mode.
How do the external RC timing networks set frequency and pulse width on the HEF4047BT?
The HEF4047BT frequency is set by external capacitors (typically 0.01 µF to 10 µF) and resistors (1 kΩ to 10 MΩ), allowing astable frequencies from 0.01 Hz to 5 MHz. For example, with 1 µF capacitor and 100 kΩ resistor, the oscillation frequency is approximately 10 Hz. Monostable pulse width is similarly programmable using the timing capacitor and discharge resistor values.
What supply voltage range and power consumption characteristics define the HEF4047BT performance envelope?
The HEF4047BT operates from 3 V to 15 V supply with typical quiescent current of 5-10 µA and dynamic current rising to 50 µA in astable mode at 1 kHz oscillation. The wide supply range makes it suitable for single-cell battery circuits at 3 V and dual-supply systems at ±12 V, with output swing matching the supply rail voltage.
Which timing and control applications benefit from the HEF4047BT 14-pin PDSO package?
This classic 4000-series IC is widely used in debouncing circuits, precision pulse generators, frequency dividers, tone generators for audio applications, and phase-locked loop timing networks. The 14-pin PDSO surface-mount package enables compact designs in automotive climate control, industrial process timers, and consumer appliance control boards supporting 5 V to 12 V logic systems.
