HCF4041U – SGS

The HCF4041U, manufactured by SGS (now STMicroelectronics), is a quad true/complement buffer integrated circuit fabricated using CMOS technology. Introduced in 1999, this device provides four independent non-inverting and inverting buffers within a single package. Each buffer stage exhibits high input impedance and low output impedance, making it suitable for driving capacitive loads and buffering signals in digital logic systems. The HCF4041U operates over a wide supply voltage range, typically 3V to 15V, and features standardized symmetrical output characteristics. Its primary function is to provide increased drive capability and signal isolation, preventing loading effects and ensuring signal integrity. The device is commonly available in a 14-pin DIP or SOIC package and is pin-compatible with other 4041 series buffers from different manufacturers.
