Design a Custom BoardAbout This Component
Octal bus transceiver with tri-state outputs for bidirectional data transfer between buses at different voltage levels. Operates across 4.5V to 5.5V with TTL-compatible inputs and high-impedance output control. Commonly used in data acquisition systems, microcontroller interfaces, and legacy digital systems requiring level shifting and bus isolation.
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.
