The CD4041UBK3 is a quad line driver buffer with complementary outputs from Harris Corporation, part of the 4000B CMOS family. It operates from 3V to 18V, offering flexibility for both low-voltage portable and high-voltage industrial systems. Each of the four channels provides both true and inverted outputs, enabling differential signaling and balanced drive. With 38mA source and sink capability, it can drive LEDs, relays, or long transmission lines. The device is specified for -55°C to 125°C, ensuring reliable operation in extreme conditions. Packaged in a 14-lead CFlatPack, it is ideal for compact, high-performance designs.
- Complementary Outputs: Provides both true and inverted signals, eliminating the need for external inverters.
- High Drive Current (38mA): Drives LEDs, relays, and long cables directly.
- Wide Supply Range (3V-18V): Compatible with multiple logic levels and power rails.
- Quad Channel Configuration: Saves board space by integrating four drivers in one package.
