Overview
The CD4047BPWR is a CMOS low-power monostable/astable multivibrator produced by Texas Instruments. This device is designed to operate in both monostable (one-shot) and astable (free-running) modes, making it versatile for various digital circuit applications. It features a special CMOS oscillator configuration that ensures lower power consumption, which is crucial for designs requiring high noise immunity and low power dissipation.
The CD4047BPWR is packaged in a 14-pin TSSOP (Thin Shrink Small Outline Package) and is RoHS compliant, meeting the current EU RoHS requirements. It operates over a wide temperature range of -55°C to 125°C, making it suitable for a broad range of environmental conditions.
