74LS240 Octal Inverting Buffer/Line Driver | 3-State Outputs | DIP-20 Through-Hole

Description

The 74LS240 is a high-speed, octal inverting buffer and line driver designed for high-performance bus-oriented systems. This device contains eight inverting buffers organized as two groups of four, each controlled by separate active-LOW output enable (OE) pins. When the output enable is LOW, the device inverts the input signal at the output; when the enable is HIGH, the outputs enter a high-impedance (3-state) condition, isolating the device from the bus.

Utilizing Low-Power Schottky (LS) TTL technology, the 74LS240 is engineered to provide the high current drive necessary to interface with capacitive buses or heavy loads, making it an essential component for system expansion. The DIP-20 through-hole package is ideal for educational training, breadboarding, and traditional PCB assembly.
