Design a Custom BoardAbout This Component
Octal buffer and line driver with 3-state outputs, operating at 4.5V to 5.5V logic levels. Provides high-current drive capability for bus buffering and signal conditioning applications. Commonly used in systems requiring isolation between logic stages or driving external loads with minimized delay and low output impedance.
Package: SOIC-20W (7.5mm wide) · 20 pins
Why does this need a breakout?
The 1.27mm pin pitch makes hand-soldering this 20-pin SOIC challenging and error-prone. A breakout board brings all pins to standard 0.1" spacing, enabling reliable breadboard prototyping and simplifying development of USB-to-UART interfaces without requiring reflow soldering or specialized equipment.
