The CD4050B is a hex non-inverting buffer from the CD4000 CMOS series, featuring push-pull outputs. It operates over a wide 3V to 18V supply range, providing exceptional flexibility for mixed-voltage systems. With a sink current of 48mA and source current of 8mA, it can drive substantial loads. The 16-SOIC package and -55°C to 125°C temperature range make it suitable for industrial and automotive applications requiring high-voltage interfacing and robust signal buffering.
- Wide 3V to 18V Supply Range: Enables interfacing with high-voltage systems (12V, 15V) without additional level shifters.
- High Sink Current (48mA): Can directly drive relays, LEDs, and other moderate-power loads.
- Push-Pull Outputs: Provide strong, low-impedance drive for improved noise immunity.
- Extended Temperature Range (-55°C to 125°C): Suitable for harsh environments.
High-Voltage Level Shifting
With a 3V to 18V supply, the CD4050B can interface between low-voltage logic (e.g., 5V) and high-voltage systems (e.g., 12V or 15V). This is essential in industrial control panels where sensors operate at higher voltages.
Driving High-Current Loads
The push-pull output can source 8mA and sink 48mA, making it capable of driving relays, small solenoids, or LED arrays directly, reducing the need for external driver transistors.
CMOS-to-TTL Interfacing
In mixed-logic systems, the CD4050B can buffer CMOS outputs to drive TTL inputs, ensuring proper logic levels and preventing loading issues.
Oscillator and Clock Buffering
The high-voltage capability allows it to buffer clock signals in high-voltage analog circuits, maintaining signal integrity over longer traces.
Automotive Battery Management
In 12V automotive systems, the CD4050B can buffer signals from battery monitoring ICs to the ECU, withstanding voltage transients due to its wide supply range.
Industrial Process Control
In PLCs and process controllers, this buffer can distribute control signals to multiple actuators, providing the necessary current drive and voltage compatibility.
