The CD4047BFX is a low-power monostable/astable multivibrator manufactured by Intersil Corporation (now Renesas). It's a versatile CMOS integrated circuit used for generating precise timing pulses and oscillations. The 'BFX' suffix often indicates a specific package type (e.g., SOIC) and temperature range.
Applications
- Timing circuits: Used in applications requiring precise timing pulses, such as timers and clocks.
- Frequency dividers: Divides input frequencies by a specified factor.
- Pulse generators: Generates pulses of specific durations.
- Time delay circuits: Creates controlled time delays.
- Touch control systems: Used in touch-sensitive applications.
Features
- Monostable and astable operation: Can be configured for either monostable (one-shot) or astable (oscillator) operation.
- Low power consumption: CMOS technology enables low power operation.
- Wide operating voltage range: Operates over a wide voltage range.
- High noise immunity: CMOS logic provides excellent noise immunity.
- Buffered outputs: Provides buffered outputs for driving other circuits.
Benefits
- Precise timing: Generates accurate and stable timing pulses.

Additional Details
The CD4047BFX can be configured using external resistors and capacitors to set the timing parameters. It features complementary outputs, providing both a Q and Q-bar output. The monostable mode generates a single pulse of a specific duration when triggered, while the astable mode generates a continuous stream of pulses. The trigger input is typically edge-sensitive. Renesas datasheets (formerly Intersil) offer detailed specifications, including timing equations, input characteristics, and output drive capabilities.
