HLF 74HC540 Octal Buffer/Line Driver; 3-State; Inverting – DIP20 | High-Speed CMOS Logic | 2V–6V, –40°C to +85°C | Through-Hole Package

The HLF 74HC540 is a high-speed CMOS octal buffer/line driver featuring inverting outputs and 3-state capability for direct bus interface applications. Each of the eight drivers has an individual high-performance inverting buffer, controlled by two output enable inputs (OE1 and OE2) that provide active-low enable functionality for flexible data control.

Engineered for bus-oriented systems, memory interfacing, and digital signal buffering, the 74HC540 ensures low power dissipation, fast propagation, and superior noise immunity. The DIP20 through-hole package makes it ideal for educational, industrial, and prototyping environments.
