The CD4041UBFX is a quad buffer and line driver from the 4000B logic family, designed for applications requiring high output drive and wide supply flexibility. Operating from 3V to 18V, it delivers 38mA of sink and source current per channel. Each of the four channels provides complementary outputs, simplifying designs that need both true and inverted signals. Housed in a robust 14-pin CDIP package, it operates reliably across -55°C to 125°C, making it suitable for industrial, automotive, and military-grade environments.
- Wide 3V to 18V Supply Range: Compatible with 5V, 12V, and 15V systems, reducing the need for multiple voltage regulators.
- Complementary Outputs: Provides both true and inverted signals from a single input, saving external inverter ICs.
- High 38mA Drive Capability: Can directly drive relays, LEDs, and long cables without additional buffer stages.
- Extended Temperature Range (-55°C to 125°C): Suitable for harsh automotive and aerospace environments.
High-Voltage Industrial Control Buffering
With a 3V to 18V supply range, the CD4041UBFX can directly interface with industrial sensors and PLCs operating at 12V or 15V rails, providing robust signal buffering without external level shifters.
Complementary Clock Distribution
The complementary outputs allow simultaneous generation of CLK and CLK# signals for driving differential clock lines in noisy environments, ensuring signal integrity over longer PCB traces.
Driving High-Capacitance Loads
Each of the four line drivers can source or sink 38mA, making it suitable for driving long cables, relay coils, or large parasitic capacitances in test equipment.
Analog Switch Replacement
In low-frequency analog applications, the complementary outputs can be used to drive transmission gates or analog switches, providing clean control signals across the full 18V swing.
Automotive ECU Signal Conditioning
The wide temperature range (-55°C to 125°C) and high-voltage capability make it ideal for under-hood automotive ECU applications, buffering sensor signals and control lines.
Power Supply Sequencing Logic
Use the complementary outputs to generate power-good and power-fail signals simultaneously, enabling precise power sequencing in multi-rail systems.
