Design a Custom BoardAbout This Component
Octal buffer and line driver with dual independent 4-bit outputs and 3-state control. Features two output enable pins for independent control of output stages, input clamp diodes for overvoltage tolerance, and wide supply range (2.0V–6.0V). Automotive-qualified (AEC-Q100 Grade 1) with TTL-level inputs; suitable for bus interface and signal conditioning applications.
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.
