The CD4050BD3 is a 6-channel non-inverting buffer from Harris Corporation, part of the CD4000 CMOS logic family. It operates over a wide 3V to 18V supply range, making it versatile for both low-power and high-voltage applications. With 8mA source and 48mA sink capability, it can drive multiple loads. The 16-SOIC package is compact for space-constrained designs. Ideal for level shifting, signal buffering, and industrial control interfaces.
- Wide 3V-18V Supply Range: Compatible with 3.3V, 5V, 12V, and 15V systems, reducing design complexity.
- 6 Independent Channels: Buffers multiple signals in a single package, saving board space.
- Extended Temperature Range (-55°C to 125°C): Suitable for military and automotive applications.
- High Input Impedance: Prevents loading of source circuits, preserving signal integrity.
Level Shifting from 5V to 3.3V
With a 3V-18V supply, the CD4050BD3 can shift 5V logic down to 3.3V for interfacing with modern microcontrollers.
High-Voltage Industrial Sensors
In 12V or 24V industrial systems, this buffer translates sensor signals to logic levels for PLC inputs.
Driving Multiple CMOS Loads
The 6 channels can buffer clock or control signals to multiple ICs, preventing fan-out issues.
Battery-Powered Equipment
Operating down to 3V, it is suitable for battery-operated devices, buffering signals with minimal power consumption.
Automotive ECUs (12V Systems)
With -55°C to 125°C range, it handles harsh automotive environments, buffering ignition and sensor signals.
Audio Signal Buffering
In analog audio circuits, the high-impedance inputs and low output impedance buffer signals without loading sources.
