Frequently Asked Questions
What are the key operating modes of the CD4047BNSR?
The CD4047BNSR supports two primary operating modes: monostable (one-shot) and astable (free-running). In monostable mode, it generates a single output pulse of defined width upon triggering, with retriggerable capability to extend the pulse. In astable mode, it operates as a continuous oscillator with a 50% duty cycle, making it suitable for clock generation and timing applications.
What is the maximum output current and load capacitance of CD4047BNSR?
The CD4047BNSR has a maximum output low current (I(ol)) of 4mA and supports a load capacitance (CL) of up to 50pF. These parameters make it suitable for driving standard CMOS and TTL logic inputs in low-power circuit designs.
What are typical applications for the CD4047BNSR?
Typical applications include pulse width modulation, frequency division, missing pulse detection, watchdog timers, and general-purpose oscillator circuits. The retriggerable input makes it especially useful in industrial control systems and automotive electronics where reliable timing and pulse generation are critical.
What package type is the CD4047BNSR and are there alternative package options?
The CD4047BNSR comes in a 14-pin Small Outline Package (SOIC), designated R-PDSO-G14 per JESD-30 standards. Texas Instruments also offers the CD4047B in DIP (through-hole) and other surface-mount packages, providing flexibility for different PCB layout and assembly requirements.
