Design a Custom BoardAbout This Component
Octal buffer and line driver IC with dual 4-bit outputs and independent output-enable controls. Operates across 2V to 6V supply range with 3-state outputs suitable for bus driving and address buffering. Provides ±6mA output drive at 5V, 11ns typical propagation delay, and low 80µA maximum quiescent current.
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.
